| Dec-27-22 | | Brenin: 24 axb4, pinning the Black Q and threatening Rxa6+ with mate, forces 24 ... Qxa1+ 25 Kf2, and now there is no defence against Ra5. |

| Dec-27-22 | | King.Arthur.Brazil: I saw the line: 24. axb4 ♕xa1+ 25. ♔f2 ♖c8 26. ♗xc8 ♕a7 27. ♖a5 ♕xa5 28. ♕xa5+(?) ♔b8 29. ♗h3. I liked it, since the King loves to capture enemy's ♕ (you know)... But, speaking without kidding: 28. ♕xb7# is the correct move. Before <Brenin>'s comment, sure 26...♕a6 is also bad, because after 27. ♖a5 ♗d7 follows the same 28. ♕xb7#. |
|
| Dec-27-22 | | saturn2: Black wants Qxb6 and Bxd7. 24.axb4 prevents both and whhite wins Q+B for 2 R after 24.axbB Qxa1 25.Kf2 followewd by Ra5. Since the N can reach c7 quickly mate is plausible but so far I did not calculate. |
|
| Dec-27-22 | | saturn2: Black was completely outplayed after nine moves.9...Ng8 was poor. |
|

 | | al wazir: After 24. Qxa6+ bxa6 the game is resignable: 25. Bxe8 Bxc3 (25...Rxe8 26. axb4) 26. Bxc6+ Ka7 27. bxc3. Black is a piece down. |
|
| Dec-27-22 | | jrredfield: I missed the text move which leads to a mate in 12. Instead, I chose 24 Bxe8. This still wins but more slowly. 24 Bxe8 Qxb6 25 axb4+ Qa6 26 Rxa6+ bxa6 27 Bxc6+ Ka7 and after that I wasn't sure but White certainly appears to have a winning endgame at this point. |
|
| Dec-27-22 | | Mayankk: The very first thing I noticed is that the unpuzzle-like line 24 Qxa6+ bxa6 25 axb4 Bxd7 26 Rxa6+ Kb2 27 Rfa5 should lead to an easy endgame for White, being two pawns up, strong connected Rooks and a Knight ready to jump to a strong c5 outpost via a4. I then noticed the the tactical puzzle-like exchange sac of 24 axb4 Qxa1+ 25 Kf2 which leaves Black facing an impending mate on the open a-file via 26 Ra5+ Qxa5 27 Qxa5#. Even a Queen exchange versus RB isn't able to ward off the mate for long it seems. In a live game I will likely go for the simpler and obvious line. |

 | | FSR: 24.axb4! Qxa1+ 25.Kf2! is murderous. White threatens not merely to win the queen but to mate with Ra5+. Black has to surrender gobs of material, e.g. 25...Rc8 26.Ra5+ Qxa5 27.Qxa5+ Kb8 28.Bxc8 Kxc8 29.Qa8+ Kc7 30.Ne4. |

 | | Once: The prosaic 24. Qxb4 snaffles a safe piece as the threat of Ra5 pinning doesn’t give black time to capture the Bd7. |

 | | agb2002: White has a bishop, a knight and a pawn for the bishop pair. Black threatens Qxb6 and Bxd7.
The black king cannot move. This suggests 24.axb4 Qxa8+ 25.Kf2: A) 25... Qxb2 26.Q(R)a5#.
B) 25... Bxd7 26.Ra5+ Qxa5 27.Qxa5#.
C) 25... Rc8 26.Bxc8 Qa7 27.Ra5 wins.
D) 25... Rd8 26.Qxd8+ Ka7 27.Ra5+ Qxa5 28.Qxa5+ wins. E) 25... Qa6 26.Ra5 Bxd7 27.Rxa6+ bxa6 28.Qxa6#. F) 25... c5 26.Rxc5 wins. |
|
| Dec-27-22 | | AlicesKnight: Found 24.axb4 Qxa1+ 25.Kf2 with winning outcomes to follow. Two on CG for wartime codebreaker Harry Golombek in recent days. |
|
| Dec-27-22 | | goodevans: <saturn2: Black was completely outplayed after nine moves.9...Ng8 was poor.> 9...Ng8 was indeed very poor. I saw 9...Nb6 10.B-moves Nfd5 as an obvious improvement and maybe the more complicated 9...b5 would have been even better. Having got away with a somewhat dodgy opening, from 9...Ng8? onwards over the next few moves Golombek was able to put a choking stranglehold on his opponent. Here's the position after 13...Be8. 
click for larger view... at which point Golombek let him back out again with 14.Bxf6?? Why on earth would you do that? Was he just feeling sorry for him? Sajtar's freedom didn't last long though. Seemingly in some sort of panic his K made a rush for the corner with 16...Kb8? and once again Golombek was able to box Black in, only this time it was terminal. |

| | FSR: Not a great puzzle. I found the "official" solution, but almost any plausible move wins. |
|
| Dec-27-22 | | TheaN: <24.axb4> wins, given after <24....Qxa1+> else White just wins a queen for rook and is likely still mating <25.Kf2 +-> and Black has no proper way to defend against Ra5+. These combinations always look a bit scary, surrendering a rook with check, but this one wasn't too complicated. |
|

 | | Honza Cervenka: After 10.e6 the game was quite apparent opening disaster for black but 14.Bxf6? gave away all advantage of white. 15...Qc7 could have given black a decent game but 15...Qh5?! and especially 16...Kb8?? sealed the outcome of the game. |
|

| | FSR: A bad game by both players. |
