| Feb-20-14 | | patzer2: Well, maybe not so rare! Thanks <<offramp> for the link to Van der Wiel vs Karpov, 1987 with Van der Wiel's 9. Bg6!! |

Feb-20-14
 | | FSR: <patzer2> Here are assorted games where one side or the other played a Bg6 sacrifice: Sacrifice Explorer There are a lot of them, so I haven't looked to see whether any resemble this game. Here is a fun game I remembered where Black plays a <queen> pseudo-sacrifice on g3: H W Apperly vs H Charlick, 1894. |
|
| Feb-20-14 | | Cheapo by the Dozen: There are a lot of variations here, and I certainly messed up some key ones. But I think finding the first move didn't have to be that difficult. My path was basically: A. Nxe6 looks good.
B. Gotta do something about the f-pawn to pull Nxe6 off. C. Qh5 doesn't work at all.
D. Nxf7 misses the point, as there's no Nxe6 followup. E. Hey -- Bg6 actually works! |
|

| | FSR: I thought of Bg6 quickly, I think because I'd recently looked at a Sicilian where White, who had pushed a pawn to g5 and now had his queen on h3, played g6. If Black took with the h-pawn, his rook on h8 would hang to White's queen. If he took with the f-pawn, Nxe6 would be strong. The motif in the present game was similar except that it was a bishop rather than a pawn that moved to g6. |
|
| Feb-20-14 | | patzer2: <FSR> Thanks! |
|
| Feb-20-14 | | gofer: White wants to play Nxe6 winning the queen, but first Pf7 needs to be
pinned or removed. The position of all the other pieces allowd the
rather unusual...
<16 Bg6! ...>
16 ... Rf8?
17 Bxf7+ Rxf7
18 Nxe6 
16 ... Qc7?
17 Bxf7+ Kd8/Kf8
18 Nxe6+
16 ... Nf8?
17 Bxf7+ Kd7
18 Bxe6+ Kc7 (Nxe6 19 Nxe6 )
19 Nf7/Bxc7
16 ... fxg6
17 Nxe6
All this really only leaves black with one alternative... <16 ... hxg6>
<17 Qxh8+ Bf8>
<18 dxc5 ...>
Its not over but white has won a pawn, is an exchange up and
has lots of possibilities...
~~~
Agggh! I missed out castling. I saw it, but thought that it was
far too dangerous, but it looks almost playable! |

| Feb-20-14 | | agb2002: The material is identical.
The light squares around the black king look vulnerable, the rook on h8 is defenseless and the black queen can move to c7 only. These details suggest 16.Bg6 with many threats (17.Nxe6, 17.Nxf7, 17.Bxf7+, 17.Qxe6, etc.): A) 16... fxg6 17.Qxe6
A.1) 17... Qc7 18.Qf7+ Kd8 19.Ne6#.
A.2) 17... Nb8 18.Nb6 Qd5(6) 19.Qf7+ Kd8 20.Ne6+ Qxe6 21.Qxe6 Rc6 22.Qb3 Rxb6 23.dxc5 Rc6 24.Rfd1 + - [Q+2P vs B+2N] (24... Bxc5 25.Bxb4+). A.3) 17... Nf8 18.Qf7+ Kd7 19.Nxc5+ Kd6 (19... Rxc5 20.Rxc5 + -, the bishop is pinned; 19... Kc6(7) 20.Nce6+ wins the queen) 20.e4 with the threats 21.e5+ and 21.Bf4+ looks disastrous for Black. A.4) 17... Ne5 18.dxe5 recovers the piece and keeps the attack (18... Qxd2 19.Qf7+ Kd7(8) 20.Rfd1 + -). B) 16... hxg6 17.Qxh8+ Bf8 (17... Nf8 18.Qxg7 + -) 18.dxc5 + - [R+P vs B] (18... Nxc5 19.Nxc5 Qxd2 20.Nce6 Rxc1 21.Qxf8+ Kd7 22.Qd8+ Kc6 23.Qxd2). C) 16... 0-0 17.Bxh7+ Kh8 (17... Nxh7 18.Qxh7#) 18.Bf5+ Kg8 19.Nxe6 fxe6 20.Bxe6+ Rf7 21.Bxf7+ Kxf7 22.Nxc5 Nxc5 23.dxc5 + - [R+4P vs B+N] (23... Qxd2 24.Qxc8). D) 16... Qc7 17.Bxf7+ Kf8 (17... Kd8 18.Nxe6#) 18.Nxe6+ Kxf7 19.Nxc7 + - [Q+2P vs B+N]. |

 | | Penguincw: 16.Bg6 was pretty easy to spot, but I didn't expect black to castle. |
|
| Feb-20-14 | | johnlspouge: I looked at direct assault
16.Nxe6 fxe6 17.Bg6,
seeing that Nxe6 traps Qd8. Then I realized: Qh3 pins Ph7 to Rh8, so Pf7 is overburdened with defense of g6 and Pe6. Hence, 16.Bg6. |

23. Qh8 is reminiscent of Petrosian's 30th move in this game. A nice pattern to remember! Petrosian vs Spassky, 1966 |
|
| Feb-20-14 | | Nick46: An absolutely Fressinating configuration. |
|
| Feb-20-14 | | kevin86: White will regain the queen and be ahead a rook and two pawns for a bishop. |
|
Feb-20-14
 | | doubledrooks: I voted for 16. Bg6, taking advantage of the Black queen's lack of mobility and the pin on the h7 pawn. |

| Feb-20-14 | | galdur: <chrisowen> Nice job indeed. Like spoken from my own heart. |
|
| Feb-20-14 | | Juninho: <patzer2: Can't recall a game with a Bishop (sham) sacrifice, where the win involves making a Bishop vulnerable to capture by two pawns> here it is:
Anand vs Lautier, 1997 |
|
| Feb-20-14 | | CopyBlanca: I wonder what the computer suggest for black's 11th move. maybe 11...h6 is better with a plan to keep the black king in the center even. |
|
| Feb-20-14 | | CopyBlanca: Has anyone mentioned that chrisowen is trying to imitate James Joyce's FINNEGAN's WAKE? Now he is very good at it I must say. |
|
| Feb-20-14 | | cjgone: Saw the move and many continuations to pin black's queen, etc. but did not anticipate the castle. |
|
| Feb-20-14 | | mel gibson: I thought 16 Qxe6 but not the best solution.
This puzzle was tricky. |
|
Feb-21-14
 | | al wazir: <FSR: Bad dog!> I thought it was a pretty decent try. And after 20. Nce4 I would have played 20...Qxc1 21. Nxf6 Qxf1+ 22. Kxf1 Rc1+ 23. Ke2 Bxg2+! 24. Qxg2 Bxf6. (At this point black is a piece down and can resign without disgrace.) But Houdini's line is better. |
|
| Feb-22-14 | | patzer2: <Juninho> Thanks for the link to Anand vs Lautier, 1997. Anand's 21. Bg6!! is indeed another brilliant and beautiful move <where the win involves making a Bishop vulnerable to capture by two pawns>. |
|
| Feb-22-14 | | Cheapo by the Dozen: The idea after Move 20, culminating in the queen sac/knight fork, feels like it should be a common one. But I don't recall ever actually seeing it before. |
