1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be2 Bg7 7.Be3 a6 8.O-O O-O 9.f4 Qc7 10.Bf3 e5 11.Nb3 Nc6 12.Qd2 {BvR.I spent 20 minutes, deciding on this move. Most of it to calculate the consequences of 12.Nd5? As I only found out afterwards: a very bad option.jb. move 12.. ne5, not ef4 (this does not make sense, jb. You mean 13...Ne5?(BvR) fritz16 say equal.queen d2 is not a good my by fritz16} exf4? {BvR. A mistake, if only because it creates a weak pawn on d6, and also gives white the open f-file.jb. the position is equal by fritz16. BvR. Perhaps equal, but much easier to play for a win by white than by black (see reasons above).} 13.Bxf4 Rd8 {knight e5 instead of rook d8 is equal by fritz16 jb. But then black wil be under considerable pressure, after Rad1.BvR} 14.Rad1 Bg4? {BvR. Now black can't avoid the loss of the exchange} 15.Bg5 $40 Bxf3 16.Rxf3 Qb6+ 17.Kh1 Ng4 18.Bxd8 Rxd8 19.Nd5 Qa7 20.c3! Nce5 21.Rff1 Bh6 {BvR. 21..Nec4; 22.Qe2, Nce3; 23.Nxe3, Nxe3; 24.Qf2!, would ultimately lose the pinned knight} 22.Qe2 Kg7 23.Nd4 {+4.4} Bg5 24.h3 Nf6? {BvR. White now will win a piece via a cute, little combination} 25.Nxf6 Bxf6 26.Qf2 {BvR. The threat is 27.Ne6+ or Nf5+ with the loss of blacks queen. Or 26.Rxf6, Kxf6; 27.Qf2+ ... followed by a knight move, with the same effect.} {#r}
