[#]The Botvinnik System. This is a kind of "formula" opening, since White's
setup --- c4, e4, d3, g3, Nc3, Bg2, Ne2 -- can be played almost without
looking at what Black does. White also gets a safe position without conceding
space. All of which make it an appealing repertoire choice for White.   Even
so, strong players should not be unhappy to face it as Black: unlike other
formula openings -- the London, Colle, King's Indian Attack, Hippo -- the
Botvinnik creates a more strategically complex middlegame, since the central
pawn tension can be resolved in different ways by both sides, and because the
only likely piece exchanges -- knights on d4 or d5 -- also dramatically change
the pawn structure. So there is plenty of scope for the better player to prove

d5 $1 {[#]A pseudo-sac which turns the game into a Benoni where both of
Black's Bs are misplaced: Black's LSB concedes f5 and imagining some of the
following postiions with the black B on g7 will show you how much better it
would be there.  This line is so good for White that the strongest Black
players do not risk 6...c5 against their closest rivals, but go for ...00 and .

he'd be able to outplay his lower-rated opponent in the complications....
