 | | al wazir: After 24...Qxe3 white has an alternative line: 25. Qxb7 Qxf2 (25...Ng3+ 26. fxg3 Qxg3 27. Qxa8+ Kg7 28. h3 Rh5 29. Qc8 f5) 26. Qxa8+ Kg7 27. h3 Ng3+ 28. Kh2 Ne2 29. Ra1 Rg5 30. d6. It still loses. |

 | | An Englishman: Good Evening: Noticed that others also thought of Marshall's immortal ...Qg3!! brilliancy. Took a bit of thinking to figure out exactly how to use the g3 square, but have already consumed a fair amount of brandy tonight... |
|
| Feb-10-21 | | Refused: 24...Qxe3 -+
a) 25.fxe3 Ng3+ 26. Rh5#
b) 25.Qxe5 Qxe5 is hopeless
c) 25.Nd6 trying to muddy the waters with Qxf7+ ideas. but 25...Re7 puts an end to that shenanigans, and white is just a rook down. |

 | | agb2002: Black is two pawns down.
The white king has no legal moves and the pawn on f2 is overburdened with the defense of the rook on e3 and the square g3. Therefore, 24... Qxe3 and if 25.fxe3 then 25... Ng3+ 26.hxg3 Rh5#. |
|
| Feb-10-21 | | saturn2: 24...Qxe3
If white retakes 25.. fxe3 there is forced mate... Ng3+ 26. hxg3 Rh5 |
|
| Feb-10-21 | | saturn2: In blitz I would have dared the probably incorrect 18....Nxg2 just to bother white. |
|
| Feb-10-21 | | Brenin: It's not hard to see the key move 24 ... Qxe3, but seeing how to deal with 25 Nd6 (necessary to claim a complete solution) makes this quite hard for a Wednesday puzzle; it was a Friday puzzle 15 years ago. |

| Feb-10-21 | | goodevans: 'Might have been' puzzle: How could black have gained an advantage if white had played 24.h3?

|
| Feb-10-21 | | Brenin: <goodevans>: The Stockfish recommendation 24 h3 exf2 25 Qxe5 Ng3+ 26 Kh2 Nf1+ 27 Kh1 fxe1=Q could continue 28 Qxf4 (not 28 Qxe1 Qh2#) Ng3+ 29 Kh2 Qxg1+ 30 Kxg3 (not 30 Kxg1 Ne2+ and Nxf4) and Black has the exchange for a pawn, but with White's d-pawn looking strong the game is far from over. |

 | | LRLeighton: Goodevans' puzzle would make an excellent Saturday. After 24 h3, I found 24...exf2 25 Qxe5 (everything else gets mated), Ng3+ 26 Kh2, and now 26...Nf1+ with double discovered check. But here I got stuck. Black can repeat knight checks with perpetual (which I probably would do OTB), because after 27 Kh1, the obvious 27...fxg1(Q)+ leads to a R+N ending a pawn down. I had to check the computer -- I will leave it for the next person to solve as it is quite pretty, but it would be difficult to see it all starting from 24 h3. |

| | LRLeighton: In the 24 h3 line, Brenin is correct that 30 Kxg3 is better for white than 30 Kxg1, but after 30...Re8, I doubt that white's pawn on d6 is even relevant -- white's King is in a lot of trouble, and it is likely that he will be giving up more material to save it. |

| Feb-10-21 | | mel gibson: Top move.
White can't take that Queen or it's mate in 2.

| Feb-10-21 | | Cheapo by the Dozen: Fun one. No smothered mate. No useful discovered attack on the queen; indeed, there probably wouldn't be even if she were undefended. But the double sacrifice works quite nicely, and White's defensive trick turns out to fail. |
|
| Feb-10-21 | | awfulhangover: Far mor easy than this week´s Monday and Tuesday. Maybe its a pattern recognition case. |
|
| Feb-10-21 | | Diana Fernanda: Now the puzzles have a higher degree of difficulty and, thanks to them, the level of play of the panelists will increase. Good Morning |

 | | Fusilli: A beautiful thing about this puzzle is that Qxe3 is not a luxury. If the white queen weren't where it is (and were in some other unhelpful square) Rxe3 would work too (the mate would be Qh6). So, Qxe3 is beautiful and the best too. What's up with all those extra moves by white? |

| Feb-10-21 | | Granny O Doul: @Walter Glattke: Karpov was on the wrong end in Karpov vs Taimanov, 1977 , while
O Dementiev vs Dzindzichashvili, 1972 saw both players miss the combination. |
|
| Feb-10-21 | | 1g1yy: <Walter Glattke: 24.-Qxe3 25.fxe3 Ng3+ 26.hxg3 Rh5# wellknown mate combination, Karpow got a mate with Ng3+ where a black bishop attcked g1 and there was no f-pawn, but I don't remember to the opposite and another match were there with that combination, today this mate would no be played as surprise, so it was last century.> I was all proud of myself seeing that and figured, I've got it! Ahh, no... lol. I'm surprised black didn't resign earlier given the desperation moves with the N at 25/26. It staves off a bloodbath for a little while and I suppose with an error could have led to a draw once the white king was opened up. But, it was long hence a lost cause unless black completely falls asleep. I'm relatively new to the site and play at maybe a little better than a beginner level. Also have not followed chess in 3 decades. Do masters really work this stuff out this far in advance or do they simply decide on a line that looks like it'll work and follow it to fruition? Even with unlimited time, I simply can't work this far out (8-10 moves) and EVER come up with the solutions to these longer lines. Monday and Tuesday... eh maybe. I even got an "insane" Saturday or Sunday once... Emphasis on once. I never came within a mile since. These puzzles are the most fun I've had on the internet in quite a while. Even if I'm not very good at em. |

| Feb-10-21 | | Damenlaeuferbauer: This is a famous game, the 1st game of the FIDE Candidates round of the last 12 (plus Tolya Karpov, who was seated in the semi-finals) in Wijk aan Zee 1994. After long thinking, the 18,5 years young Vladimir Kramnik finally found the problem-like move 24.-,Qxe3! 25.Nd6 (25.fxe3,Ng3+ 26.hxg3,Rh5#) 25.-,Re7 26.Nxf5,gxf5 and was a rook up for just two pawns. |
|
| Feb-10-21 | | Halldor: I tried to exploit the stalemate position of the White King (Ng3+ hxg3?? Qh6#), but couldn't get it to work. But for similar mate pattern with Rook on h5 after the Knight sacrifice the Queen wasn't needed. So then at last I tried: 24... Qxe3!! 25 fxe3 (otherwise White will lose a piece, right...?) Ng3+ 26 hxg3 Rh5# However, I didn't anticipate the clever continuation of the game from 25 Nd6. |
|
| Feb-10-21 | | drollere: here is how patzer does it: Nxe3, fxe3, Qxe3 and black is up the exchange and ready for Re7 if necessary. |
|
| Feb-10-21 | | Brenin: <drollere>:After patzer's 24 ... Nxe3 25 fxe3 Qxe3 26 Qxb7, White has two connected passed pawns for the exchange, and I can't see patzer getting more than a draw out of the position. |
|
| Feb-11-21 | | Nullifidian: 24... ♕xe3 picks up the rook for free because if 25. ♙fxe3, then ♘g3+ 26. ♙hxg3 ♖h5#. |
