| Jul-29-09 | | luzhin: In such an ultra-sharp Sicilian, Black has to be extra-careful not to lose time with his own attack: 16...Nc4 looked essential, but presumably Black missed the devastating 22.Bxe6! |

 | | beenthere240: After 22. Bxe6, the bishop can't be taken because of 23. Rh8+ followed by mate (much as in the game). |

 | | Korora: Well, I was right about a sacrifice being involved, but I guessed the wrong piece. |
|
| Feb-01-23 | | jrredfield: I went for 22 gxf7+ thinking of 23 Bxe6 as a follow-up. But it appears that gxf7+ keeps things pretty even, whereas 22 Bxe6 leaves Black with no good counter-moves in the vicinity of the king. 22 ... fxe6 leads to a mate in 3 (23 Rh8+ Kxh8 24 Qh3+ Kg8 25 Qh7#). Black basically is defeated at this point, just stalling with moves like 22 ... Bxb2+. |
|
| Feb-01-23 | | outplayer: I have found the move. |
|
| Feb-01-23 | | Brenin: The retreat 16 ... Nc6 is hard to understand, when 16 ... Nc4, threatening 17 ... e5 18 Be3 Nxa3, would have added wings to Black's Q-side attack. After 20 h5, 20 ... gxh5 looks better than 21 ... Bf6 played, e.g. 21 Bd4 e5, but is there an answer to 21 Bf5, e.g. 21 ... exf5 22 Rxh5? |
|
| Feb-01-23 | | EasilyConfused: 22..Rfb8 was not a good defense. A little better is 22..Bxb2+ 23 Kxb2 Qxc2+ forcing exchange of Queens and so avoiding immediate mate. But after 24 QxQ NxQ 25 gxf7+ Rxf7 26 KxN Black is in trouble, going to be down a R for a pawn when White captures the pinned Rook |
|
| Feb-01-23 | | Mayankk: My line was 22 Bxe6 Bxb2+ ( 22 ... fxe6 23 Rh8+ Kxh8 24 Qh3+ Kg8 25 Qh7#) 23 Kxb2 Qxc2+ 24 Qxc2 Nxc2 25 exf7+ Rxf7 26 Kxc2 when White will be up a Rook and a Bishop. I didn't plan for the 22 .. Rfb8 defense. It has some traps e.g. 23 Rh8+ Kxh8 24 Qh3+ doesn't work and we need the intermezzo 24 Bxf7 first. Also after 24 ... Bxb2+, 25 Kxb2 doesn't work since Black can sacrifice more pieces with 25 ... Nf3+ 26 Rxf3 Bxe4+ etc. to introduce complications and harass the White King. |
|
| Feb-01-23 | | King.Arthur.Brazil: My line is not forced and seems predictable: 22. Bxe6 fxe6 23. Rh8+ Kxh8 24. Qh3+ Kg8 25. Qh7#. But Black is not forced to capture the ♗ and can counter attack with 22... Bxb2+ 23. Kxb2 Qxc2+ 24. Qxc2 Nxc2 25. Kxc2 fxe6. In the resulting position, Black has one ♙ more, while White has a dangerous ♙ in g6, in final of 2♖ and one ♗ of opposite colors too. Time to check. |

The open h-file suggests 22.Bxe6:
A) 22... fxe6 23.Rh8+ Kxh8 24.Qh3+ Kg8 25.Qh7#.
B) 22... Rfb8 23.Rh8+ Kxh8 24.Bxf7 Qxf7 25.gxf7 g6 26.Qxg6 wins. C) 22... Rfc8 23.Rh8+ Kxh8 24.Bxf7 Bxb2+ 25.Kb1 (25.Kxb2 Qxc2+ 26.Qxc2 Rxc2+ 27.Kb3 Rh2) 25...

| Feb-01-23 | | Refused: 22.Bxe6 should be curtains.
The g6 has to be kept alive for the well known mating pattern rh8+ Qh2+ Qh7#. That's the motif you have to spot. The only minor headache is whether white could get mated first (typical sicilian kings on opposite sides of the board stuff). I don't see an immediate k.o. punch for black, thus 22.Bxe6 and 1-0 |

| Feb-01-23 | | ET3 Hefley: 22. ♗xe6! opens the path along the h-file threatening ...♖h8+ with ...♕h3+ and mate coming |
|
| Feb-01-23 | | TheaN: <22.Bxe6! +-> is one of those shots that only become more beautiful as you look at the end result. People fault Brandenburg for 22....Rfb8, but what else? 22....fxe6 is the point: 23.Rh8+ Kxh8 24.Qh3+ Kg8 25.Qh7#. So moving the rook gives some air. Whilst objectively 22....Bxb2+ may be the best try, Black's toast after 23.Kxb2 Qxc2+ 24.Qxc2 Nxc2 25.gxf7+ +- winning a rook for a pawn. After the text, a few ways win: Giri's way is flashy, but Bxf7+ and gxf7+ win relatively easily too. White just needs to be wary to not let the king escape to e7 without control, because the bishop can fall back to defense, and all of a sudden Black's attacking. |

 | | scormus: <Thean .... 22 ... Rfb8>
I agree, there was no real option. Silicon might give it a worse eval than ... Qxf2+, say, but B's only possibility of avoiding a loss was to keep open the chance of counterplay in the event W might stumble in his attack. The text move was B's best bet. FWIW, when choosing 22 Bxe6 and 23 Rh8+, I did realise that W's bridges were burned and couldn't afford the attack to stall. |
