 | | wordfunph: total annihilation 35.Rh6! white rook asking the black queen, where are you going? |

 | | drollere: my first thought was that this was a position that only chess software could love. after about a minute, i chose
20. Nxg5 hxg5
21. h6 Bh8
22. h7+ Kf7
23. Bxg5 Ke8
24. Rh6
but lost the thread in black's countermoves.
it's interesting that black's position is weak because he has no pawn support for his pieces, and needs three pawn moves to catch up, while defending threats. meanwhile, white only needs one pawn move to clear the way for the Q. |

 | | agb2002: The position suggests 20.Nxg5 (20.Bxg5 hxg5 21.Nxg5 Bh6) and a quick scan yields: A) 20... hxg5 21.Bxg5 followed by g4 opening the g-file or the b1-h7 diagonal. B) 20... f4 21.Qd3
B.1) 21... hxg5 22.Qh7+ Kf7 23.Bf5+ wins decisive material. B.2) 21... Rfd8 22.Qh7+ Kf8 23.Bxf4 hxg5 24.h6 looks winning. C) 20... Nxe3 21.Qxe3 hxg5 (21... f4 22.Qd3 as in B) 22.Qxg5 followed by h6 recovers the piece (22... Kh7 23.Qg6+ Kg8 24.h6). |
|
| Jun-20-20 | | Brenin: Black can decline the sacrifice with 20 ... Qc6 (defending h6), e.g. 21 Nh3 Nxe3 22 Qxe3 Bxa2+ 23 Kxa2 Qxc2, with material equality. Alternatively, he can accept the sacrifice, and then after 20 ... hxg5 21 h6 offer the piece back with Bf6, defending g5. Neither line looks very attractive, but they are probably better than the line played. |
|
| Jun-20-20 | | stacase: One of those little sayings when you post says, "Knights on the rim are dim" so maybe White can get two pawns for that dim bulb and play it by ear after that. |
|
| Jun-20-20 | | Brenin: 24 ... f4, preventing White from getting the Q into the attack with 25 f4 and 26 Qh3, and threatening counterplay with Ne3 and c5, would have been a better defence than the passive 24 ... c6. Later, 25 ... Rc7 looks pointless; why not the obvious Be6, overprotecting the P on f5, and allowing Qd5 and Kd7. And 26 ... e6 was a blunder, empowering the B on g5 and denying the K an escape route via d8, but Black was probably lost anyway by then. |

Knights on the rim are dim and worth no more than two pawns, at least that's what I came up with and I'm no grand master my best game was a win over a guy rated 1500 almost 30 years ago. |

| | Predrag3141: Thanks!
All of White's evaluations seem to go down with time. Shorter runs than 25 minutes posted above seem to put White up a little more than a pawn. At 25 minutes Nxg5 was slightly in favor of White and it eventually went down to equal; and Bb3 was equal, and it eventually went down to slightly in favor of Black. |
