With this move the knight heads immediately for the weakened b4 square, keeping options open for developing the queen s bishop. It may go to g4 pinning white s knight, or even attempt to hold the extra pawn by going to e6. Black often tempts White to take the knight on a6. This would weaken black s pawns, but it would also give up the two bishops - usually more than enough compensation. The side variations are pretty standard book recommendations except for the risky exchange grab against the Geller Gambit. I hope you enjoy this quickie Slav System monograph. Hogeye Bill
