| Jun-25-09 | | ungeneral: why did white feel the urge to play 16.Be2 and giving up the rook? Would have been better to play 16. Rg1 first and then Be2? |
|
| Jun-25-09 | | Shams: 16.Rg1 Nf5 17.Be2 Qb2 wins a piece. |
|
| Sep-10-10 | | wordfunph: 17...Bh3!! simply astounding.. |
|
| Sep-23-21 | | Honey Blend: 12. ... ♘c6 is tagged as an exchange sac, but if I'm not mistaken it wins the exchange. Am I missing something? |
|
| Sep-23-21 | | Brenin: My choice was the quieter 12 ... Nbd7, e.g. 13 Qd4 Rxe7, and Black has plenty of compensation for the P. |
|
| Sep-23-21 | | Cheapo by the Dozen: 15 ... Rxe7 wins less dramatically.
So why is this a puzzle? The game move was obviously appealing. |

 | | raymondhow: I followed the game line till I wanted to play 15...Qxa2+ followed by Rxe7. Being up the exchange plus a pawn seems decisive. |
|
| Sep-23-21 | | latebishop: I thought that 12...Nbd7 13.Qd4 Nb3, winning the exchange is also effective. |

I was too busy looking at other moves.

 | | agb2002: Black has a knight for a bishop and two pawns.
White threatens Bxc5 and Bd4.
The white queen protects c3. This suggests 12... Nxc6: A) 13.Qxc5 Qxc3+ 14.Kf2 Qxa1 wins an exchange and a pawn and threatens Qxa2+ and Rxe7. B) 13.Qf6 Ne4 14.Qh4 Qxc3+ wins decisive material. -----
The alternative 12... Nbd7 13.Qd4 Nb3 14.axb3 Qxa1+ 15.Kf2 doesn't look as strong as 12... Nc6 because the knight is much better placed on c6, touching e7 and not blocking the bishop, than on d7. |

 | | Teyss: Yesterday I solved the puzzle but wouldn't have found it OTB, today it's exactly the opposite. Looked at fancy moves like 12...Rxd7 or Bg4 but thought Nc6 was too trivial. OTB would have played it since it develops a piece, attacks the Q and the P, prevents a future Bd4 and most of all wins the exchange: if 13.Qf6 keeping control of c3, Ne4 with a strong attack. Even though White did not play the best moves afterwards and is lost at the end, 17...Bh3 is a real puzzle move. <Honey Blend: 12. ... ?c6 is tagged as an exchange sac, but if I'm not mistaken it wins the exchange.> Yes surprising, don't know how tags are done, probably automated hence some glitches. "13.Qxc5" would have been more accurate although White has nothing better so it's no a sac. |
|
| Sep-23-21 | | Cellist: Like others, I thought 12. ... Nc6 was a good move but rejected it as a puzzle solution, looking for something more "puzzling." I checked 12. ... Rxe7, but Black is too poorly developed and vulnerable for it to work. In the game, White chose some sub-par moves later on, for example 16. Be2.
I agree that Black's last move (Bh3) is quite impressive. |

| Sep-23-21 | | GlennOliver: Ambivalent between -
12. ... Nc6
or 12. ... Nb3 (followed by the Queen exchange)
Either one gives Black a very playable game, though by no means an assured win. |
|
| Sep-23-21 | | johnnydeep: I got the first few plys pretty quickly. "Attack the white queen to force it away from defending against the king-rook fork by the black queen". But one move by white was baffling to me: 16.Be2. Huh? Why just give up the other rook? |
|
Sep-23-21
 | | Jimfromprovidence: Black wants to play ...Qxc3+, winning the rook, but the white queen protects c3. So the problem is basically can black force the queen from protecting that square. 12...Nc6 definitely does that as others have pointed out. So why does not 12..Rxe7 work? if 13 Qxe7 then black can try 13...Qxc3+, seeing 14 Kf2 Qxa1.

| Sep-23-21 | | landshark: Anybody got analysis on 15... Bg4 instead of the game move 15... Nxe7? I don't have Premium so I can't get engine analysis on it - but it was my idea, going for rapid development, planning ... Rxe7 next followed by .... Rae8. |

Rae8.> At about a minute SF14's top choices are ...Rxe7, ...Qxa2+, or ...Bf5, each around -6. 15....Bg4 is somewhat weaker (though certainly no weaker than ....Nxe7) because it allows 16.Ne5 and the pawn on e7 survives a little longer. But Black has a completely winning position at this point and pretty much any non-blunder is fine. |
