| Jul-16-22 | | jrredfield: Black managed to crawl its way to a win despite missing the much better move 28. ..Nxh3! which wins decisively. 29. Re3 Rxe3 30. Qxe3 Be5+ 31. Kh1 Nf4+ 32. Rh2 Qxh2 33. Kxh2 Nxd5 34. Qxe5+ Pxe5 and Black coasts to victory. I also considered 28. ..Rh2 to win the queen which really leads to a very close game, which makes that move considerably inferior to 28. ..Nxh3 but is still better than the text move. |
|
| Jul-16-22 | | Brenin: My idea was 28 ... Nxh3, and if 29 Rxh3 then 29 ... Be5+ 30 Kg2 Qg4+ 31 Kf2 Qxh3, and Black is ahead by 2P, passed and connected, surely enough for a win. |
|
| Jul-16-22 | | Granny O Doul: Also disappointing is that Black missed 33...Qe1+, as in a famous FSR game. |
|
| Jul-16-22 | | BxChess: <Granny O Doul:> Well-spotted. 33...Qe1+ is such a nice move. |

I thought 28...Re2+ but Stockfish is only giving a score of -1.5 for White.Stockfish 15 says:

The bishop can check the white king from e5. This suggests Be5 and Nxh3. In the case of 28... Nxh3:
A) 29.Rxh3 Be5+ 30.Kg2 Qg5+, followed by the capture of the rook, recovers material and exposes the white king even more. B) 29.Kg2 Qg4+ 30.Rg3 (30.Kf(h)1 Qg1#; 30.Kh2 Be5+ wins) 30... Nf4+ 31.Kf2 (31.Kh2 Qh4+ wins) 31... Qh4 must be winning. For example, 32.Qd1 Rf8 33.Qg4 Nxd5+ wins decisive material. C) 29.Re3 Be5+ and the attack looks winning. For example, 30.Rxe5 Rxe5 wins material and keeps the attack. Or 30.Kg2 Qg4+ 31.Kf1 Rf8+ 32.Rf3 Rxf3+ 33.Bxf3 Qxf3+ 34.Ke1 Bg3+ wins decisive material |

 | | scormus: I thought I'd got this with my 28 ... Be5, followed by the next 2 text moves. Never thought .... Nxh3 was the best. |
|
| Jul-16-22 | | Boerboel Guy: I got 28....Nxh3 ! :-) |

|
| Jul-16-22 | | TheaN: Partial credit for this at least, as I noticed 28....Re2+? 29.Qxe2 Nxe2 30.Rxe2 must be inferior to the other options, and 28....Be5!? is good but not best, as after <28....Nxh3! 29.Rxh3 Be5+> it comes with tempo and <30.Kg2 Qg4+ -+> recovers material with much more crushing options. It's a shame that in the text, Black missed 33....Qe1+! #3. |
|
| Jul-16-22 | | stst: thinking of Be5 to pin, instantly or after the N-sac of 28. .... Nxh3, but White can ignore the N temporarily and Re3 will block.
28..... Be5 pins and W left in a lurch. |
|
| Jul-16-22 | | stst: too blind to see why (following the text moves) 33.... Qe1+ is winning, as Be5 is blocking R@e8 (KxR then.) Even after a dis+ Black is not winning instantly, as Kf1 or Kd1 are easy escapes. |
