{This is the second game where I lost a drawn rook endgame. However, it was not a rook endgame at first. I got outplayed in the opening, then I made a comeback and eventually, I lost. The game is filled with inaccuracies and blunders due to intense time pressure but it was quite interesting and instructive. Lastly, this was my second time playing Titas. The first time was in 2021 and I lost quite badly. Despite losing the second game, I felt like it was a good indication of how I improved (since I had decent chances to make a draw). Our third encounter occurred in November 2024 where I played much better and got a draw as Black, and eventually, my second IM norm.} 1. Nf3 d5 2. g3 Nf6 3. Bg2 c5 4. O-O g6 5. c4 Bg7 6. Qa4+ Bd7 7.

{This is round 3 of the Sevilla Open, my first game against a higher-rated opponent.} 1. e4 c5 2. Nf3 d6 3. Bb5+ {The Moscow Variation, a popular way to avoid the Open Sicilian. I had not prepared for it.} Nd7 {[#] This line is more fighting and less drawish, which is why I had studied it. I generally play for a win, but it is better to be more flexible and knowledgeable of more than one or two lines to avoid preparation or to surprise your opponent. My opponent capitalized on this by eventually achieving a favorable position from the opening.} 4. O-O a6 5. Be2 $5 {This is the third most played move in this position. However, I do not consider it particularly popular or well-known. I was already out of my preparation, as I had mainly focused on 3.d4 with the intention of playing the Najdorf.} Ngf6 6. d3 g6 $5 {Although this is not a mistake, it gives White a lasting structural advantage that is difficult to counter. It is somewhat unusual, as ...g6 is typically played after White "wastes" a tempo on d3, since d4 is the ultimate goal.} (6... e6 {is best.}) 7. c4 Bg7 8. Nc3 O-O 9. d4 cxd4 10. Nxd4 {[#] White achieves his ideal setup. I strongly believe he chose a sideline specifically to reach this position against a Maroczy structure, knowing that I do not play the Benoni or the Dragon, leaving me with little experience here. As a result, I felt very uncomfortable and was dissatisfied with how the opening unfolded.} Nc5 11. f3 Qb6 12. Kh1 Bd7 {[#]} 13. Rb1 {Protecting the b2-pawn so that White can develop the dark-squared bishop.} (13. b3 {was best as it protects the b-pawn, allows White to play e3 next and prevents a4.}) 13... Na4 $1 {White has significantly more space to develop his pieces. Therefore, it benefits Black to trade off as many pieces as possible.} 14. Nxa4 Bxa4 {[#]} 15. b3 (15. Qxa4 Qxd4 {is not a mistake objectively. However, positionally speaking, White's knight on d4 was much more active than Black's light-squared bishop, which is why White should avoid trading the two pieces.}) 15... Bc6 16. Be3 Qc7 17. Qd2 Rfc8 18. b4 Qd8 {[#]} 19. Rfc1 (19. Nxc6 bxc6 (19... Rxc6 20. a4 {is even better for White.}) 20. a4 $1 $16 {White is better, as b5 is imminent. Opening the position favours White due to the strong and active bishop pair, while Black's pieces remain passive.}) 19... Be8 20. Bf1 Rab8 21. Nb3 Ba4 22. Nd4 Be8 {[#] Why am I repeating? Firstly, my position is worse. Secondly, I am extremely uncomfortable with the structure, and my opponent is aware of it. Thirdly, he is significantly higher rated than me. Therefore, I had no objections to a draw.} 23. Qf2 $6 {Avoiding the repetition. From the start, White applied significant positional pressure, but his last few maneuvers were too slow, despite being natural and reasonable.} (23. Nb3 Ba4 24. c5 {was best and gave White very decent chances due to the pressure on the queenside.}) 23... b5 {[#] Finally, I am able to create some counter-play, gain some space and disrupt White's pawn structure.} 24. cxb5 (24. c5 {was the best way to maintain some decent pressure on Black's position. Black must play some kind of waiting move as ...dxc5 is unfavorable.} Qc7 (24... dxc5 25. bxc5 {allows White to create a passed pawn that controls significant space and cannot be easily captured, as the isolated pawn is more of a strength than a weakness in this position. An isolated pawn often becomes a strength rather than a weakness once it reaches the fifth rank.}) 25. cxd6 Qxd6 26. Rd1 Qc7 $14) 24... axb5 25. Rxc8 Qxc8 (25... Rxc8 26. Nxb5 $18) 26. Rc1 Qa6 {The most active square for the queen as it is protecting the b5-pawn and attacking White's a2-pawn.} 27. Qc2 Bd7 {[#] Although the position is now equal, I still lack space, and my pieces are not optimally placed, especially with many tied down to defending the b5-pawn. Therefore, repositioning the bishop to a more active square is a good move.} 28. Qd2 Ne8 {A multi-purpose move: first, it defends c7, preventing White from invading with c7. Second, it opens the a1-h8 diagonal for my strong dark-squared bishop. Third, it creates the possibility of developing the knight to d6 if ...d5 is achieved.} 29. Rc2 {This move has two ideas. First, it allows White to double on the c-file with c1 if desired. Second, it prepares the sneaky idea of a4!, putting significant pressure on the b5-pawn. If Black captures with the queen, as the b-pawn is pinned by White’s light-squared bishop, a2! follows, trapping the queen.} Qa8 {Removing the queen from the f1-a6 diagonal and threatening to open up the position in Black's favour!} 30. Bf2 {[#]} Bf6 {This move protects the e7-pawn, which could become vulnerable in some lines, frees the g7-square for the king or knight if needed, and places the dark-squared bishop on a more active square.} (30... d5 $1 {was possible without losing any material as} 31. exd5 Qxd5 32. Rc5 {was well-met by} Qd6 $1 {retaining the pin on White's knight, preventing all ideas of capturing on b5.} 33. Bg3 {leads to a drawn endgame} Qxd4 34. Qxd4 Bxd4 $11 {both d5 and xb8 are possible for White.}) 31. Qc1 d5 $1 {Black is now the one applying pressure on White's position.} 32. exd5 Qxd5 33. Nb3 Nd6 {[#] Activating the knight in the center of the board where it controls the most squares and removing the threat of d2 as Black's dark-squared bishop will not be caught in the cross-hairs.} 34. Bg3 Ra8 {Activating the rook on a semi-open file, as the b5-pawn no longer needs protection, while also unpinning the knight.} 35. Rd2 Qh5 $1 {[#] Black can now try to put some pressure on White's king.} 36. Nc5 (36. Bxd6 $2 exd6 {would be a positional mistake as the bishop was elemental in keeping White's king safe. Moreover, it gives up control of the dark squares as Black's bishop would start taking over.} 37. Rxd6 $4 Be5 $19 {White's rook is hanging and Black is threatening mate with ...xh2#. White cannot defend against both threats.}) 36... Be8 {Black's bishop is much stronger than it was in the opening. The position is now open, where bishops thrive. Placing it on c6 would expose it to discovery attacks due to White's queen on c1. Although e8 appears passive and defensive, it is the best move, especially since Black can later reactivate the bishop by gaining better control of c6.} 37. Qd1 $6 {Somehow, this move that seems to add pressure to the d-file and remove all possible threats of ...g5 is an inaccuracy!} (37. Bxd6 exd6 38. Ne4 {would have maitained equality.}) 37... Qh6 $1 {The start of a nice positional manoeuvre.} 38. Re2 Nf5 39. Bf2 Bc6 {Black's last few moves were very active and contributed to the improvement of the position.} 40. Kg1 Qf4 $1 {One of the ideas behind ...h6! Although Black's queen is well-placed on the h-file, it cannot create enough pressure to force White into further weaknesses. Therefore, it must be reactivated to an even more active square.} 41. Nd3 $2 Qd6 $1 $17 {[#] The queen is now centralized. Instead of exerting pressure solely on the h-file, it now attacks both the b4- and h2-pawns while pinning White's knight. This is its optimal placement, and recognizing that it no longer belonged on the h-file was an important realization. During the game, my moves felt natural. I aimed to play faster to avoid severe time pressure while also putting clock pressure on my opponent. Interestingly, while preparing, I noticed he was strong in blitz (mostly online), yet during the game, I saw that the clock was visibly stressing him. This led me to believe he might struggle under time pressure.   I used to think that a good chess player should take their time, calculate carefully, and prioritize strong moves over managing the clock. Playing quickly seemed to reflect impatience and a lack of skill, despite many games being decided by time rather than the position. However, I have recently come to appreciate the benefits of playing faster when possible and now recognize that fast-playing opponents should not be underestimated.   Regarding the position itself, my opponent and I analyzed it after the game and on our way back to our accommodation, and he expressed genuine appreciation for my queen maneuver. (Receiving compliments on my play from higher-rated players will always be nice!)} 42. Qb1 $2 {White should have tried to reactivate his pieces to a better squares with either c2, d2 or c5.} Nd4 43. Re3 Bd5 44. Nc1 Be5 {[#] With little time left, my opponent panicked and chose the most natural move.} 45. Rxe5 $2 (45. h3 {would have weakened his king greatly and although Black is still winning, it is far from over as some precision is required to seal the deal and I was still under time-pressure.}) 45... Qxe5 46. Nd3 Qf6 47. Qb2 Nxf3+ 48. gxf3 (48. Kh1 Qxb2 49. Nxb2 Rxa2 $19) 48... Qxf3 {Black resigned as Black's attack was too strong while ...h1 was either going to lead to mate or the loss of White's queen.} 0-1

{After two consecutive losses against strong, higher-rated opponents, I was in a must-win situation to secure my first IM norm, as 6.5/9 was required based on my opponents' average ratings.

{This was round 7 of the Southwest Class Championship, organized by the Continental Chess Association. Players are required to bring their own chess sets and clocks, with games using delay rather than increment. Pairings are released only shortly before the round.

{This was Round 8 of the Canadian Zonal. I was leading the tournament with a score of 6/7, while two players trailed closely with 5.5/7, and Penny had 5/7. The stakes were high, as this game was crucial for retaining my title, qualifying for the Olympiad, and securing a spot in the Women's World Cup.} 1. d4 Nf6 2. c4 c5 3. d5 b5 {[#] Penny chose a dynamic opening, as expected. Given the tournament standings, my preparation before the round had heavily focused on reviewing these types of lines (such as the Benko, Dutch, and possibly the King's Indian Defense), anticipating her need to play for a win.} 4. cxb5 a6 5. e3 {[#] This was a line I had in my files for quite some time but had never had the opportunity to play over the board, which caught my opponent by surprise. The idea behind 5.e3 is to delay resolving the queenside structure. The plan usually involves playing c3, a4, and eventually e4. The kingside knight can go to f3 or e2, depending on Black's development. In the current position, Black's queenside remains undeveloped, which highlights the advantage of delaying the exchange of a/b pawns, even at the cost of a tempo (e2-e3 followed by e3-e4).} g6 6.

I believe it showcases my understanding of rook endgames quite well. At this point, I did not have much time left, so I was trying to play as quickly as possible. The brilliance of f5 lies in the fact that it forces the kingside into one of two options: either two doubled f-pawns or a lone g-pawn. Both options are easily drawn if there are no other pawns. Of course, with the queenside pawns still on the board, reaching a draw becomes much more difficult, which is why there were blunders on both sides along the way. A fun fact: after the game, one of my friends, who was spectating, told me that another GM, who was sitting next to me while still playing his own game, had been observing the position. Based on his facial expression, it seemed he thought I would lose. However, when he saw me play f5+, his expression and posture changed, indicating that he realized it would not be so easy for White.

However, my opponent did not repeat the position three times, and we simply agreed to a draw. I believe, out of respect for my opponent, the organizers allowed it, as we had been playing for quite a long time by that point.   Overall, this game meant a lot to me. It was my first time drawing against a 2600+ player. Recently, I had lost three drawn rook endgames to players rated 2400, 2500, and 2600, despite studying these endgames and having a solid understanding of them. However, putting that knowledge into practice is another matter, which is why I am so happy to have managed to survive a losing rook endgame against such a strong opponent.} 1/2-1/2

{This was round 6 of the World Chess Olympiad, where we were paired against Belgium. Based on ratings, we were favorites to win the match. In general, it is difficult to know in advance who you will face for certain, as board pairings are only released at 10 AM for a 3 PM game, leaving limited time for preparation. However, board ones often play each other, especially in the women’s section, where there is often a significant strength gap between board 1 and other players. In this case, Belgium’s boards 2 and 3 were performing very well, while their board 1 was struggling with 0/5. Given this, my team and I expected I would likely face their board 2. Still, I had to split my preparation to be ready for both possibilities.} 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Bb4 {[#] The Ragozin.  In my opinion, and that of many others, this opening is extremely solid. I generally avoid playing this way against lower-rated opponents, as White can steer the game into very drawish positions, with some lines even leading to forced repetitions. To highlight its solidity, I have played it six times in classical games, scoring +2 =4 -0 against decent opposition — a strong statistical result.   Regarding this game, my initial preparation was focused on a more aggressive approach. However, before the game, I started doubting whether I had prepared it thoroughly enough and felt it was too risky. As a result, I made a last-minute decision to play the Ragozin, as it is a straightforward system. I also mentally accepted that a draw was a likely outcome, depending on my opponent’s choice of line—though some variations do offer plenty of life and activity.} 5. Bg5 h6 6. Bxf6 (6.

I prefer keeping pieces on the board to maximize winning chances. Second, I have little experience in such positions, as I usually avoid them, believing they are too drawish. That is why I am especially proud of how I kept generating chances, fighting throughout, and ultimately securing the win. I believe one of the key differences between good players and stronger ones is their ability to create winning chances even in equal or slightly worse positions. This game reinforced that my hard work was paying off, that I was improving, and that I could maintain or even increase my rating—I had recently reached 2300 and was working to keep it. During the game, I kept reminding myself, Magnus would win this—so what would he do? Somehow, that mindset worked! Lastly, this game had a huge impact on my tournament at the Olympiad. My win was critical for securing the match victory, and it also set me up in the best possible mood before the rest day. I believe that break helped me relax and led to strong play and a great performance for the remainder of the tournament.} 0-1

So, while a4+ may initially seem like a loss of tempo, White often regains it in other ways, leaving Black's coordination slightly compromised.} Nd7 8. Nf3 O-O 9. Be2 c5 10. Qa3 {[#] The point of a4+ is to force Black to exchange the c- and d-pawns before the knight can move away from d7 to a more active square. Once the pawns are traded, White's queen gains activity by exerting pressure along the a3-f8 diagonal, creating additional challenges for Black's development.} cxd4 11. cxd4 Nb6 {A decent alternative to ...f6, which is best. This was my first time reaching this position.} 12. Bg5 f6 13. Bd2 {[#] The idea behind retreating the bishop to d2 instead of e3, where it could provide additional protection to the d4-pawn, is based on anticipating Black's next move: ...f5. My reply to f5 will be ...e5, which relinquishes control of the d5-square. This allows Black's knight to occupy d5 and target my bishop on e3. Additionally, the bishop on e3 would be vulnerable to a future f-pawn push, making d2 a safer and more practical square for the bishop.} f5 14. Bb4 $2 (14.

If I play xf8, Black can respond with xf8, attacking my queen while my knight on f3 remains hanging. The reason d5 is such a game-changer is that it blocks the a2-g8 diagonal, preventing me from playing the intermediate move b3+, which would have saved my queen and allowed me to protect my knight next. With the knight now hanging, moving it would leave the d4-pawn vulnerable, as well as expose the a1-h8 diagonal, further weakening White's position.} (15... Qc7 $2 16. Bxf8 Bxf8 17.

{This was round 7 of the 2026 Canadian Women's Zonal. Yunshan Li and I are leading the tournament with 6.5/7. We drew each other in round 5. Meanwhile, Svitlana suffered an early loss to a weaker player and is trailing us by half a point. As a result, I had a feeling she would play e4 to push for a win. I, on the other hand, was hoping to win, but did not want to take too many risks as a loss would hurt my chances of winning the tournament greatly.} 1. e4 e5 2.

Nf3 Nc6 3. Bc4 {[#] This begins what turned out to be my worst tournament ever, at least in terms of rating loss. A part of it was focusing too much on openings and not enough on calculation. A part of it was playing underrated American juniors who all gained 200-300 points in the months after this tournament. And a part of it was making impractical opening choices, such as the one in the game. Such was the post-COVID rollercoaster. I was trying to switch to more reputable openings from my Scotch, but play them uniquely. Too uniquely as it turns out.} Bc5 4. c3 Nf6 5. d4 exd4 6. b4 {[#] I had bought a Chessable course on this Dubov Italian, and was itching to use it.

{I'd like to show this game to demonstrate the lows of every chess player's life.  This tournament was taking place in Krakow, Poland, which would be a lovely vacation if it wasn't such a horrible tourney for me.

{Going into round 2, you realize that the direction of your tournament rests on this game. A win will lead to playing up and fighting on the top boards, while a loss or a draw means you're stuck playing talented masters who are lower rated while you're not in your best form.} 1. d4 Nf6 2. c4 Nc6 {[#]  Knights' Tango When playing kids, one of the last advantages I can still claim is knowing more sidelines which they haven't learned to refute yet!

The answer, I suppose, is that Black has caught up in development and White's extra space is not an advantage with two pairs of minors gone.

In a way it was a sort of bluff, as I'm hoping that Black believes me that taking the knight on a3 is scary for her. Karina spent over 15 minutes here, trying to decide what to do with this knight.

{Coming into this game, I finally got to the territory where a win would let me cross 2400 and get me to IM. I was tempted to go all out, but knew that Vignir was playing well and was still the heavy favourite in this game.

Here however, White has more ambitious options than defending with a3.} 6. O-O Nc2 {[#] After the game, he told me that he hadn't expected the rook sac line, and looked at it the night before by accident. I wish I had more such accidents!} 7. Nh4 {I knew that this and cxd5 were the two branches here, and h4 felt more solid to me. It was already strange playing this variation against a strong GM, but I didn't have anything else for the occasion.

{I was super nervous going into this game, knowing if I won, I'd be an International Master. Just to explain why this mattered so much, I had spent the better part of the previous 5 years preparing and working towards this moment. Countless adventures, close calls, and heartbreaks led up to this game, which could end it all. Up to 10 minutes before the game, I was feverishly trying to review the lines that may come up, cursing myself for leaving this to the last minute.} 1. Nf3 Nf6 2. d4 g6 3. Bf4 {[#] My opening plan was: Double Fianchetto against the London, King's Indian against d4, and e5 against the English, all of which he played regularly. The problem with experienced players is they have games in a whole bunch of systems, and even if he last played the Gligoric King's Indian in the 1990s, I still had to solve my problems there. Even walking to the board, I was horrified of him playing one of the lines I hadn't solved yet. Kids, do all your analysis at home and long in advance!} Bg7 4. e3 b6 5. Be2 Bb7 {[#] According to GM Tiviakov in his "Rock Solid Chess" book, the double fianchetto works great in this move order.} 6. c4 {Jose takes up the gauntlet and tries to punish my lack of space with the principled approach of taking the center. If he gets c3 and c2 in, e4 is unavoidable where Black gets squeezed and my b7 bishop becomes a liability.} c5 {Since I may not get another chance, I go for all possible pawn breaks that undermine the center.} (6... d6 7. O-O Nbd7 8. Nc3 Ne4 {was also possible, of course.}) 7. d5 b5 (7... d6 8. Nc3 O-O 9. e4 {White manages to consolidate the center, and black gets a horrible Benoni.}) 8. O-O (8. cxb5 Nxd5 9. Be5 Bxe5 10. Nxe5 Qc7 11. Nc4 Nf6 12. O-O d5 $15 {The center takes priority over their queenside majority here.}) 8... bxc4 {[#] I never know what to do with these hanging c-pawns. Apparently it's better to keep the tension so that the white knight doesn't get too comfy on c3, but I was too tense already.} 9. Nc3 (9. d6 e6 10. Nc3 O-O 11. Rc1 {I didn't know how to evaluate this either. Black's pieces find squares, but white has targets on the c-file and a potential e5 post.}) 9... d6 {I wasn't going to tempt fate a second time, better to cover d6 forever.} 10. e4 Nbd7 {[#]} 11. Qc1 {This seemed unnatural at best. I get that Jose wants to get rid of the dragon bishop on g7 while keeping the d2 square for the knight. Yet this waste of time lets me keep the c-pawn while white doesn't fully get to reinforce their center. The remaining black pieces become respectable.} (11. Bxc4 {was the natural and best path forward, where I still have too many pieces for the space available. If I can trade off two minor pieces, life would be swell.} O-O 12. h3 Nb6 13. Be2 Qc8 14. Qd2 Ba6 15. Rfe1 Bxe2 16. Rxe2) 11... O-O 12. Bh6 Nb6 {[#] Even though there are cases where the c4 pawn is more of a nuisance than a strength like in the King's Indian Saemisch variation, here it's rapidly gaining in value, so let's keep it.} 13. Bxg7 Kxg7 14. Nd2 {White wants to get both the pawn and the outpost, but all these pieces going backward is a surefire sign that we should be going forward.} e6 $1 15. dxe6 fxe6 {[#] With the bishop coming alive on b7, black can say they solved all their opening problems.} 16. e5 $6 {White probably realized that the pawn armada after ...d5 would be too formidable, and tries to break it up.} (16. Nxc4 Nxe4 {white has a hard time getting their pawn back, considering that e4 also needs protection.} 17. Nxe4 Bxe4 18. Qc3+ Kg8 19.

Nfd5 {This is the problem with 16. e5 as a concept: White might break the pawns, but the black piece activity is becoming too much here. The f4 square, plus the long diagonal, the f-file for our rook, and the queen coming g5/h4 makes White's kingside a shooting range.} (16... dxe5 {I knew that this should also be good as black is getting excellent piece play and the king is weak on g1.

{This game took place right after I got the title, so it wasn't the most combative, although still rich psychologically. Tenerife has an artificial beach which I badly wanted to visit, but it would be irresponsible to go when every game had grand importance. So I was happy to finally go when it didn't matter anymore, on the morning of this game. Specific prep wouldn't have helped me anyways, since IM Pulvett hadn't played this 2...d7 system before. Thankfully, general prep before the tournament helped a lot here.} 1. Nf3 d5 2. g3 Nd7 {[#] The point of this line is to avoid KIA setups as black's threat of ... e5 forces white to play d4.

{The 2025 Winnipeg Open ended in a 4-way tie at the top between Mark Klusa, Isaac Wiebe, Collin Anderson, and Gabriel Hamm. Here is the final round game from board 1, which is a good enough reason to look at it, but I actually chose it for two other reasons:  1) in a position which could arise from several different openings, White plays a very sharp and tricky attempt to refute Black's play, and IMO it would be impossible for anyone to find their way through this OTB,  2) the ending has some crazy tactics and mating patterns I have never seen.} 1.

White usually plays e4 then a4-a5, waiting to see what Black does before committing the center pawns.

Here, the center is closed and Black gets the KID-player's favourite kingside pawn storm, but the hook on g3 creates extra tactics on the f-file (Xf3, Xf2) which don't happen in a mainline Mar del Plata KID, where White has f3 and e2 and Black aims for the the pawn break with ...g5-g4-g3.  The result is that if White plays the standard MdP queenside pawnstorm -- aiming to create a weakness on the queenside dark squares (d6, c7,b6) -- Black's attack hits sooner than in the MdP.

Nxg3 {(xg3 is similar) Analysis Diagaram [#] To me it's not obvious what's going on here. White's  and c3 currently neutralize Black's pressure on a2 and b3; the backward pawns on f3 and g6 are theoretically weak, but both are defended by s that don't seem to have any hope of a more active life anyway.  In fact, SF18 rates Black as winning based on plans involving exchange sacs on f3, which would undermine both the c3 and e4, and the exposed  will force White to defend both the back rank and the 2nd rank; and if White somehow manages all that, Black can create an outside passer with ...g5.  By Stockfish's reckoning, that's more than White can manage.  Here are some illustrative lines:} Rf4 $5 ({the computer's choice is to use tactics to transfer the  to f4 with:} 26...
