1.d4 Nf6 2.c4 c5 3.d5 b5 4.b3 I have maybe 5 or 6 books on the Benko, plus BCO2, MCO14, and a few other references. 4.b3 almost never gets any analysis, presumably because it is not even worthy of comment. However, I don't think this is a bad move, and it might be every bit as good as more common 4th move alternatives by White. By playing 4.b3, White effectively puts a damper on all of Black's thematic queenside play. Black will not get open-file pressure on the a- and b-pawns. While White's pawn play is now stagnant on the queenside, he does not have any weaknesses over there. Normally, White's play is not on the queenside, anyway, but in the center and on the kingside. White gives up none of his thematic play in these areas if he takes a timeout to play 4.b3 first. Black's queenside play is also stagnant on the queenside, but he really has nothing to fall back on. With this pawn structure, Black lives or dies on the queenside. As best I can tell, 4.b3 is one of those "high-class waiting moves. I cannot find many GM games with 4.b3. Masera - Benko, 1971 (I think) is probably the "model game" for this variation, but White played like a Class C player in this game so it is not very instructive. I would appreciate comments or gamescores. Thanks

If Black wants to achieve the "usual" ...g6, ...Bg7, ...d6 setup he simply plays 4... bxc4 (or possibly 4... b4) and then continues a normal Benko Gambit Declined fashion. Regards Edmond

Thank you for the game. I do believe Black's only hope is to play in Benoni fashion with an early ...e6 break. This game would seem to support that idea. I don't think Black can get away with the "usual" ...g6, ...Bg7, ...d6 moves. Regards Will
