|
Mar-28-12 | | TrollKing: Bc6! Ouch. Hate to copy Shams comment above, but it bears repeating: Nice shot. |

Mar-28-12 | | Nezhmetdinov: Bc6 made me laugh out loud - if only there were some handy internet abbreviation I could have used there... |
|
Jan-21-20 | | Cheapo by the Dozen: White would like to unblock his queen, threatening mate at g7. Black's queen needs to be diverted for that to happen. 25 Bc6 does the diversion, in that 25 Bc6 Qxc6
26 Rxd6 is horrid for Black.
However, Black can refuse to play along, leaving White up a clear exchange with some attacking chances, so I'm not totally sure why Black resigned immediately. |

Jan-21-20 | | erichbf: White goes down two exchanges,
25. Bc6, Qe7
26. Bxe8, Rxe8,
27. Nf6 check... |
|
Jan-21-20 | | agb2002: The white queen and knight aim at g7. Therefore, 25.Bc6: A) 25... Qxc6 26.Rxd6 wins decisive material (26... c(Q)xd6 27.Qg7#; 26... Re7 27.Rxc6; 26... Qxg2+ 27.Kxg2 Nf4+ 28.Nxf4 cxd6 29.Rg1). B) 25... Qf7 26.Bxe8 wins an exchange. |
|
Jan-21-20 | | Walter Glattke: 25.Bc6 Qf7 26.Bxe8 Rxe8 or 25.Bc6 Qxc6 26.Rxd6 Qxd6 27.Qg7# or 26.-Rf7 27.Rxc6
or 26.-Qxg2+ 27.Kxg2 Rf7 28.Rd1 with following threatenings, e.g. Nf6+.
25.Rxd6? cxd6 26.Bc6 Qf7 27.Bxe8 Rxe8 28.Nf6+ Kf8 29.Nxe8 Kxe8 could be draw or white advantage. |
|
Jan-21-20 | | saturn2: Saw 25. Bc6 wins because after Qxc6 black has no more controll over g7. |

Jan-21-20 | | razetime: <erichbf> 27. Nf6+ Qxf6 -+, white is down material. Better would probably be Re1. |
|
Jan-21-20 | | TheaN: What a cute way to abuse a QR-battery. Normally the square's supposed to be defended, but White's light-squared bishop doesn't give a *bleep* and just does it anyway. 25.Bc6 Qf7 (Qxc6 26.Rxd6 +- is just done, as it costs a full queen to defend g7). 26.Bxe8 +-. |

Jan-21-20 | | Damenlaeuferbauer: After long pondering, my old Russian friend Volodya, who is a nuclear physicist and together with the Moldovan Viktor/Viorel Bologan the leading expert of the Chebanenko Slav (1.d4,d5 2.c4,c6 3.Sf3.Sf6 4.Sc3,a6!?) and reached the semi-finals of the world cup 2009 in Khanty-Mansiysk, defeating the great Peter Svidler in the round before, finally found 25.Bc6!,Qxc6 26.Rxd6, winning black's queen or mating the black king. |

Jan-21-20 | | The Kings Domain: Nice puzzle, a goodie. |
|
Jan-21-20 | | TheaN: <25.Bc6 Qf7 (Qxc6 26.Rxd6 +- is just done, as it costs a full queen to defend g7).> Got to correct myself here partly. It does not win a full queen outright, as after the 'clever' 26....Qxg2+ 27.Kxg2 Nf4+ Black will negate the mate threat regardless of how White responds. However, after 28.Nxf4 cxd6, seemingly trading queen for rook (R+N for Q+B to be exact), White's not done with the attack: after 29.Nh5 the rooks cannot properly defend g7: after 29....Rf7 30.Nf6+ wins another exchange, and after the slightly more tricky 29....Re7 30.Re1! +- Black's paralyzed. |

|
Jan-21-20 | | JustStarting: <razetime> 26.Re1 Ke5 continuation? |
|
Jan-21-20 | | 5hrsolver: Nice puzzle. Unusual way to deflect the queen from guarding g7. |
