"This brilliant piece sacrifice kills Black's attempt at snatching the initiative. Lasker was once more hoping that White would grab the offered pawn. After 14 Bxf4 e5 15 dxe5 Nxe5 both 16 Bxe5 Bxe5 17 f4 Bf6 18 Bd5 Bf5 19 Bxb7 Rab8 and 16 Qxe4 Bf5 17 Qxf5 Nxc4 leave Black firmly on the offensive. After 14 Qxe4 White gains only two pawns for the piece. On the other hand, Black is reduced to a grom defensivve job, which would not suited Lasker at all." After a short time the programs I am testing have not decided it is the best move. The results so far I have are: Analysis by Anaconda 1.6.2: 1. +- (1.49): 14.Bg3xf4 2. ² (0.56): 14.Bg3-f2 3. ³ (-0.28): 14.Bg3-e1 4. µ (-0.94): 14.Qc2xe4 *** Analysis by Hiarcs 8: 1. ² (0.69): 14.Bg3xf4 e6-e5 15.d4xe5 Bf6xe5 16.Bf4xe5 Nc6xe5 17.Bc4-d5 e4xf3 18.g2xf3 Ne5-d7 19.Bd5-e4 Nd7xc5 20.Be4xh7 Qe7xe3+ 21.Kc1-b1 2. = (-0.02): 14.Qc2xe4 f4xg3 *** Steinitz,W - Lasker,E r1b2r1k/ppp1q1pp/2n1pb2/2P5/2BPpp2/P3PPB1/1PQ3PP/2KR2NR w - - 0 1 Analysis by Crafty 19.17: 1. = (0.09): 14.Bg3xf4 e6-e5 15.d4xe5 Bf6xe5 16.f3xe4 Be5xf4 17.e3xf4 Rf8xf4 18.Kc1-b1 Rf4xe4 19.Ng1-f3 Bc8-f5 20.Rd1-d5 2. µ (-0.75): 14.Bg3-f2 Bf6-g5 15.Kc1-b1 f4xe3 16.Bf2-g3 e6-e5 17.d4xe5 Nc6xe5 18.Bg3xe5 Qe7xe5 19.Rd1-d5 e3-e2 20.Ng1xe2 3. -+ (-1.53): 14.Bg3-e1 f4xe3 15.Qc2xe4 e6-e5 16.Bc4-d3 g7-g6 17.d4-d5 Qe7xc5+ 18.Qe4-c4 Qc5xc4+ 19.Bd3xc4 Nc6-d4 20.Ng1-e2 Bc8-f5 4. -+ (-2.03): 14.e3xf4 Nc6xd4 15.Qc2-a4 Qe7xc5 16.Qa4-b4 Qc5xb4 17.a3xb4 Nd4-f5 18.Rd1-e1 Nf5-d6 19.Bc4-b3 5. -+ (-2.43): 14.Ng1-e2 f4xg3 15.h2xg3 Bf6-g5 16.Qc2xe4 h7-h6 17.Kc1-b1 Nc6-a5 18.f3-f4 Bg5xf4 19.Ne2xf4 Na5xc4 ***6. -+ (-2.44): 14.Qc2xe4 f4xg3 15.h2xg3 g7-g5 16.Ng1-e2 Nc6-a5 17.Bc4-d3 Rf8-f7 18.Kc1-b1 Na5-b3 Steinitz,W (2590) - Lasker,Em [D35] GCG_008 St. Petersburg, 1895 1.d2-d4 d7-d5 2.c2-c4 e7-e6 3.Nb1-c3 Ng8-f6 4.Bc1-f4 Bf8-e7 5.e2-e3 0-0 6.c4-c5 Nf6-e4 7.Nc3xe4 d5xe4 8.Qd1-c2 f7-f5 9.Bf1-c4 Nb8-c6 10.a2-a3 Be7-f6 11.0-0-0 Kg8-h8 12.f2-f3 Qd8-e7 13.Bf4-g3 f5-f4 14.Qc2xe4 f4xg3 15.h2xg3 g7-g6 16.Qe4xg6 Bc8-d7 17.f3-f4 Rf8-f7 18.g3-g4 Rf7-g7 19.Qg6-h6 Rg7xg4 20.Bc4-d3 Rg4-g7 21.Ng1-f3 Qe7-f7 22.g2-g4 Ra8-g8 23.g4-g5 Bf6-d8 24.Rh1-h2 Rg7-g6 25.Qh6-h5 Rg6-g7 26.Rd1-h1 Qf7xh5 27.Rh2xh5 Rg8-f8 28.Rh5xh7+ Rg7xh7 29.Rh1xh7+ Kh8-g8 30.Rh7xd7 Rf8-f7 31.Bd3-c4 1-0
