 | | plang: 11..Rfe8 was a new move though not an improvement over the previously played 11..a6 as the White queen was never threatened on the e-file and f7 was very vulnerable. 16..Rc8?! was not productive and gave White time to play for an attack with 21 Rd3. 17..Bd8? was a waste of time; 17..Nd7 would have been better. |

| Nov-23-22 | | mel gibson: Many moves win here.
White's choice was the best.

| Nov-23-22 | | Brenin: I had 25 Rxf7, expecting 25 ... hxg5 26 Rxc7 Qxc7 27 Qxe8+, winning the exchange and a P. The response 27 ... Rf8, inviting 28 Rxc6 Rf1 mate, deservedly loses to 28 Rxg7+ Kxg7 29 Qxg5+ with a mating attack. |
|
| Nov-23-22 | | Mayankk: I wanted to play 25 Rxf7 hxg5 26 Rh3 Rxf7 27 Qh8# And if 25 Rxf7 Rxf7 26 Qxf7+ Kh8 27 Rh3 threatening Rxh6+ and Qh7# or Qg6 and Qh7#. |
|
| Nov-23-22 | | Confuse: Is there any refutation to 25 Rxf7 hxg5 26 Rh3? Got the same solution as Mayankk and just wanted to confirm since mel posted stockfish which didn't include that variation |
|
| Nov-23-22 | | jrredfield: I was torn between 25 Rxf7 and 25 Nxf7. I chose the latter, which wins, (as <mel gibson> stated, there are several winning moves). But the text move is the best choice by far. 25 Rf6 also wins but more slowly. |

Rd7, black has to give up his ♕ to avoid mate. |
|
| Nov-23-22 | | saturn2: 25.Nxf7 Rf8 26.Rdf3 A pawn is a pawn.
I looked ar 25.Rxf7 and 25.Rf6 as well at the later the longest. But in both are ways to go wrong.
For exampke in
25.Rf6 hxg5 26.Rh3 Kf8 27.Qxg5 Ke7 28.Rd3 Kf8 29.Rh6 the moves 28 and 29 are not trivial |
|
| Nov-23-22 | | saturn2: After 23 Qg4 the game would have been already over. |
|
| Nov-23-22 | | agb2002: White has a knight for a bishop.
Black threatens hxg5.
The black queen becomes overloaded with the defense of both rooks after 25.Rxf7: A) 25... hxg5 26.Rxc7 Qxc7 27.Qxe8+ Bf8 (27... Kh7 28.Rh8#) 28.Qxe6+ Qf7 (else 29.Rh3#) 29.Qxf7+ Kxf7 30.Rd7+ wins decisive material. B) 25... Rxf7 26.Qxf7+ Kh8 27.Rd7 Rg8 (27... Qxd7 28.Qxd7 Rf8 29.Nf3 + - [Q+N+P vs r+b]) 28.Qg6 hxg5 29.Qh5#. C) 25... Rf8 26.Qg6 Rfxf7 (26... hxg5 27.Qxg7#; 26... Rdxf7 27.Qh7#) 27.Qh7+ Kf8 28.Qh8+ Ke7 29.Qd8#. |
|
| Nov-23-22 | | agb2002: I saw Rf8 but missed it in my line A. Better luck next time. |
|
| Nov-23-22 | | Mayankk: <confuse> 25 Rxf7 hxg5 26 Rh3 only works if Black obliges with 26... Rxf7. Otherwise there is no quick mate since 27 Qh8+ can be answered by the simple 27... Kxf7 |
|
| Nov-23-22 | | Brenin: <al wazir: After [24 Rxf7] 25...hxg5 26. Rxc7 Qxc7 27. Qxe8+ Kh7 28.- Rd7, black has to give up his ♕ to avoid mate.> 27 ... Bf8 avoids mate, but after 28 Rd8 Qf7 29 Qxf7+ Kxf7 30 Rd7+ and 31 Rxb7 it's a clear win for White. |

 | | scormus: Wasn't sure whether 25 Nxf7 or Rxf7. They both looked promising, but either way I thought W would need at least a bit more work to secure a win. When I saw 25 Rxf7 So was relieved to see that SF14 gave both a clear advantage for W, but Rxf7 significantly better (ca. +10 vs. +5 for Nxf7).
Even without an engine, I'd say on reflection that 25 Rxf7 is the more definite move, and better OTB. After ... hxg5 then 26 Rxc7 Qxc7 27 Qxe8+ and it's a case of "they think it's all over ....." |
|
| Nov-23-22 | | NARC: 25. Rf6 looks good too. |
|
| Nov-23-22 | | Refused: 25.Rxf7 has to be the move in this position.
a)25...Rxf7 26.Qxf7+ is curtains
b)critical line has to be 25...hxg5 26.Rxc7 Rf8 (obvsiously not Qxc7 27.Qxe8+ Bf8 (Kh7 28.Rh3#) 28.Rd7) 27.Rxg7+!! (the key move) Kxg7 28.Qxg5+ and mate follows soon. |
|
| Nov-23-22 | | NARC: I didn't see 25. ... Bf8 |
|
| Nov-23-22 | | TheaN: For once, I saw this start to finish. And it's not that easy, but a good Wednesday because of that. <25.Rxf7> forces most in the Black camp. Perhaps the most striking line is 25....Rxf7 26.Qxf7+ Kh8 which doesn't seem to lose anything at first glance, 27.Rh3! #4. Similarly, 25....Rf8 26.Qg6! Rfxf7 (Rcxf7 27.Qh7#) 27.Rd8+ #2. <25....hxg5> so given the knight's the key piece, the other capture then. Here, <26.Rxc7> is obvious as the attack's drying up otherwise. This wins White the exchange and initiative after <26....Qxc7 27.Qxe8+ +->, this is straightforward but the best line. Black can try one more trick up his sleeve with 26....Rf8?!, but if White finds the game line with 27.Rxg7+! (to prevent the back rank mate) it's mate in 4: 27....Kxg7 28.Qxg5+ Kf7 (else Rh3#) 29.Qf6+ Kg8 (Ke8 30.Rd8#) 30.Rg3+ Kh7 31.Qg7#. Great puzzle. |
