| Feb-28-04 | | refutor: yes spielmann got enough material for his sacrifice, but the unbalanced material position is interesting |
|
| May-12-05 | | aw1988: This is a sound sacrifice, I'm willing to bet. |
|
| Apr-13-09 | | WhiteRook48: really sound |
|
| Oct-16-09 | | bengalcat47: This game appears in Spielmann's book The Art of Sacrifice in Chess. As pointed out by Reinfeld and Horowitz Spielmann failed to notice the that strong move 18. c3! keeps the Black Queen from occupying d4, and makes it possible for White to activate his central Pawn mass. |

| Feb-08-10 | | rapidcitychess: Why a draw? I'm only 1500, but I don't see a draw. Actually, I see a win in sight due to the passed e pawn. Please, show me where I am missing something. |

The score in Spielmann's book (at least in the Horowitz-Reinfeld edition) ends with 30... Kd7 1/2-1/2I am not sure what Black's drawing plan is. Spielmann, Horowitz, and Reinfeld don't comment on this. |

At first glance, Black probably plays 30...c5, and on the next move 31...cxd4. After that, it looks hard for White to advance the passed pawns. Do you see a specific way to do it? If White then pushes the d-pawn, Black takes the e-pawn. If White shifts his bishop to b3 and pushes pawns to e6 and d5, the Black pieces blockade and White's bishop is the wrong color to lift the blockade. |

That seems like a good plan. But immediately 30...c5 allows 31. d5 since if 31...Qxe5 32. Re1. That, presumably, is the point of 30...Kd7 (to be followed by c5) as played according to the Spielmann book. |

Good point, 30...Kd7 first followed later by ...c5 and the plan above. |

 | | Pawn and Two: Gillam's recent tournament book, "Ostende 1906" shows that the last move for this game was 30...Kd7. The notes to this game also included Marco's analysis, <... after 30...Kd7 31.e6+ attains nothing: 31...Ke7 32.Bxc6 Qf4+ 33.Kg1 Kxe6>. Marco stated he was of the opinion the white pawns were not as dangerous as they seemed. Fritz indicated black's best choice at move 30, was 30...Qf4: (.68) (22 ply) 30...Qf4 31.Ke2 c5 32.Kf2 cxd4 33.cxd4. After black played 30...Kd7, white certainly had the advantage, but black still had fairly good drawing chances. Fritz provided the following analysis: (.88) (22 ply) 30...Kd7 31.Re1 Qd3+ 32.Kf2 Qc2+ 33.Re2 Qf5 34.Kg3 Qd3 35.a3 h5. |

How about a more human reply with 30...Qf4 <31. Re1>, to answer 31...c5 with 32. d5 Qc4+ 33. Kg1 Qxa2 34. d6+ with a dangerous-looking attack? If not ...c5, White tries to prepare eventually c4 and d5, although I don't have time to research a line for that. |
|
Feb-10-10
| | Pawn and Two: <beatgiant> Fritz indicates after 30...Qf4, that 31.Re1 is not an improvement for white: (.52) (25 ply) 31...Qf7 32.Re2 b5 33.a3 a5 34.Kf2 b4 35.axb4 axb4 36.Rc2, (.00) (22 ply) 36...Qc4, or (.01) (22 ply) 36...g5 with an approximately equal position. |

It's always interesting to see these inhuman lines. Here, I would have expected 30...Qf4 31. Re1 Qf7 <32. b3> (now threatening to take the c-pawn without fear of ...Qc4+), followed by 33. c4 and White is on the way to preparing the central pawn push. |
|
Feb-11-10
| | Pawn and Two: <beatgiant> After 30...Qf4 31.Re1 Qf7 32.b3, white may be on the way to preparing a central pawn push, but Fritz indicates it is only good enough for equality. After black's response 32...Qf5, white could try: (.00) (23 ply) 33.c4 Qd3+ 34.Re2 Qd1+ 35.Re1 Qd3+, or (.00) (23 ply) 33.Re2 h5 34.Rd2 g5 35.Ke1 c5, or (.00) (23 ply) 33.Re4 Qg5 34.c4 Qd2 35.Re2 Qd1+, with each line giving an approximately equal position. |

| | Pawn and Two: In Gillam's tournament book, "Ostende 1906", Lasker stated that 11...Nd4 was black's best choice. After 11...Ne5, Lasker stated, <"The move actually made, should lose the game, because the following exchanges are to the advantage of White">. Lasker was correct about 11...Nd4 being black's best move. However, his conclusion that black was lost after 11...Ne5 12.Nxe5?!, was not correct. Fritz indicates that white has the advantage after: (.72) (21 ply) 11...Nd4, or (.97) (21 ply) 11...Ne5 or (.73) (21 ply) 11.Qd6. After 11...Ne5, Spielmann should have played 12.Bxc5!, with the following continuation indicated by Fritz: 12...Nxc4 13.dxc4 Re8, (.94) (22 ply) 14.h3 Be6 15.Qxd8 Raxd8 16.b3 b6 17.Bd4 f6 18.Kh2. additional analysis of this line is needed to determine if white can increase his advantage. Instead of 12.Bxc5!, the complexities of the 12.Nxe5?! line, could have allowed black to obtain equality: 12...Bxd1 13.Nxf7 Qe7 14.Nxd8+ Kh8 15.Rxf8+ Qxf8 16.Nf7+. In this line, black would get a strong advantage after 14.Bg5? Nf6!, or 14.b4? b5!, or 14.a4? Nf6!. |

| | Pawn and Two: Instead of 13...Qe7!, Schlechter obtained a lost position with 13...Rxf7??. Winning for white was then, 14.Rxf7! b5 15.Rd7+, or 14.Rxf7! Kh8 15.Rxd1. Instead of the clearly winning 14.Rxf7!, Spielmann played 14.Bxf7+?. White still had an advantage, but perhaps not winning, after 14.Bxf7+? Kh8 15.Raxd1 Nf6 16.Bxc5 b6 17.Bf2 Ng4. At move 18, as noted by <bengalcat47>, Horowitz and Reinfeld had recommended 18.c3, to keep the black queen from occupying d4, and to make it possible to activate white's central pawn mass. Lasker indicated that 18.Bd5 was an oversight, and he also recommended 18.c3 as a preparatory move to advance white's powerful center. Fritz indicates the best continuation was: (.98) (22 ply) 18.Bb3! Qg5 19.h3 Ne3 20.Bxe3 Qxe3+ 21.Kh1 h6. White could next double his rooks on the f-file by 22.Rf3 Qe2 23.Rdf1, with a very strong position. After 18.c3, black has better defensive chances than after 18.Bb3!: (.52) (22 ply) 18.c3 Qg5 19.Bd5 Re8 20.h3 Ne3 21.Bxe3 Qxe3+. Spielmann played 18.Bd5, a move which considerably reduced white's advantage: (.38) (22 ply) 18.Bd5 c6 19.Bb3 a5 20.c3 a4 21.Bc2 Qd6 22.Bg3 Qc5+ 23.d4 Qc4. |

| | Pawn and Two: As noted in my last post, after 18.Bd5 c6, 19.Bb3 was white's best continuation. Instead, Spielmann played 19.Be6?. The resulting position shows the danger of leaving the bishop unprotected at e6! 
click for larger viewAt this point, Schlechter could have obtained the advantage with 19...Nxh2!: (-.68) (25 ply) 20.Rfe1 Qg5 21.Re3 h5 22.Rg3 Ng4 23.Rf1 Rf8, or (-.83) (25 ply) 20.Kxh2 Qd6+ 21.Kg1 Qxe6 22.b3 Qe5 23.Be3 Kg8 24.a4 Rf8. Instead, Schlecter played 19...Nxf2?, and after 20.Rxf2 Qd4 21.c3 Qe3 22.Kf1, the position was approximately equal. |

Feb-11-10
| | Pawn and Two: At move 22, Schlechter could have retained approximately equal chances with 22...Qh6 23.Bh3 g5, or 22...Qh6 23.Bb3 Qxh2. Instead, after 22...g6?, the position again favored white: (.69) (20 ply) 22...g6? 23.Bb3 a5. Spielmann did not play 23.Bb3, but he still retained some advantage after: (.48) (22 ply) 23.Rf3 Qh6 24.h3. |
|
| Jun-12-12 | | Anderssen99: In their analysis of this game Dr. Tartakower and Du Mont say that 19.Bxc6 would have been met by 19...,Rc8. Isn't 19...,Qd6 the right move since it threatens 20...,Qxh2 mate and 20...,Qxc6 thus winning a piece at least? |
