Dec-20-02 | | mrwonkabar: Excellent defense by Levenfish! Could white have won somewhere is the question... |
|
Dec-20-02 | | mdorothy: Ok, I have an instint move here that I want you to analyze and hopefully ill find time to also.. try 20. Qf4. It attacks the undefended knight and allows the queen much more play on attacking the kingside. The only thing I'm worried about is whether white can withstand black's attack on the queenside if he starts with 20...Nd3+? All I know right now is it looks scary, definately too scary for me to try it OTB.. |

 | | Honza Cervenka: What about 32.Nc4? |
|
Dec-03-03 | | Calli: 32.Nc4 looks good. Maybe 32.Nd4 is fine too, but didn't Black miss 30...Bb5! 31.Qxb5 Nd3+ 32.Qxd3 Qxd3? Looks forced. |

 | | Honza Cervenka: <Calli> You are right. 30...Bb5 is a nice winning shot. |

Black had to defend a poor position.

Mar-26-21 | | agb2002: Black has the bishop pair for a bishop, a knight and a pawn. Black has Qxh1 and Qe4.
After 26... Qxh1 27.Qxh1 Bxf6 28.Qxb7 Black doesn't seem to have achieved much. After 26... Qe4:
A) 27.Kd2 Rfd8 28.Bd3 Bb5 looks very good for Black. For example, 29.Rf4 Rxd3+ 30.cxd3 Bb4+ 31.Ke2 Bxd3+ wins. B) 27.Rh3 Bxf6 28.Qxf6+ Kxh7 29.Rg3 (or 29.h6) 29... Rg8 and White's attack seems to vanish without compensation for the material deficit. |

Mar-26-21 | | Walter Glattke: 26.-Qxh1!? 27.Qxh1 Bxf6 28.Qxb7!? Bg5 29.Kd2 Bc6 30.Qxa7 Rfd8+ 31.Bd3 Be4 32.Nc5 Nc4+ 33.Ke2 Bxd3+ wins, but they would not play Qxb7.
26.-Ng4 fails by 27.Bxg4. Glattke agrees with Stockfish, all other ways fail. |

No - according to Stockfish 13 -
I forced it to play 26... Qxh1
White wins instead of Black.

 | | samvega: Great puzzle. Did not get it. Bloody obvious once you see it though. It's good to have a few puzzles like this that aren't initiated by captures. |
|
Mar-26-21 | | 1g1yy: Yea, I'm gonna have to watch a few more chess game videos before I see continuations like this. :D |
|
Mar-26-21 | | 1g1yy: Could someone please explain to me 31...Bc6. Is it to stop Rf3? Surely it can't be to stop Nd5/f5 since there's already a pawn for that. Protection for the bishop using the b pawn? Of the moves in this line that seem pointless/passive to me, this has to be the most so... :shrug: |

 | | Jimfromprovidence: I saw that 26...Bxf6 was not playable because of 27 Qxf6+ Kxh7 28 Rg1, below. click for larger viewWhite threatens mate in one and black will lose the knight after something like 28...Rg8 29 Rxg8 Rxg8 30 Qxe5. But 26...Qe4 protects the black knight while attacking white's e knight making white play 27 Rh3. Now 27...Bxf6 is playable and wins a bit of material but black went with 27...Qxh7?!. |
