| Feb-28-09 | | WhiteRook48: was the bishop promotion necessary? I think not... |
|
| Apr-03-20 | | jith1207: 15 consecutive checks to the end of the game after move 27! A lot of them while leaving the King bare open in the back rank for a mate. 18 checks in last 24 moves! |

| Apr-03-20 | | jith1207: <WhiteRook48: was the bishop promotion necessary? I think not...> Yes, it's necessary as the King gets to first rank and the Queen alone, without its Rook's help, is stuck in repetition not being able to force mate or protect a7. 34...Qh3+ 35. Kxf2 Qh2+ 36. Kf1 Qh1+ 37. Kf2 Qh2+ (draw) The promotion also frees up the a file from White's Rook for the Queen to later occupy and protect a7. |

| Jun-09-24 | | Cecco: Black moves and limits white's advantage. |

| Jun-09-24 | | Allderdice83: <Yes, it's necessary as the King gets to first rank and the Queen alone, without its Rook's help, is stuck in repetition not being able to force mate or protect a7.> I think WhiteRook48 meant that Black was showing off by promoting to a Bishop instead of a Queen. I wonder how far in advance Black saw the ending. There are a lot of checks Black has to see to reach a checkmate position, all while facing the threat of mate himself. |

| | Diocletian: I wish the underpromotion were necessary because then it would be elegant, but White must capture on f1 be it a Q or a B. It's a gutsy little spite check that would have been embarrassing if Black had not won. |

| | Diocletian: Yes, he was showing off, being arrogant - and crushing White's ego. |

 | | An Englishman: Good Evening: 11/14 for the week, a big relief after the previous two weeks, but completely missed this one, and can't help but wonder if Black's 16th move constitutes the right spot for a puzzle. |

 | | PawnSac: <Diocletian: Yes, he was showing off, being arrogant - and crushing White's ego.> I don't think so. Looked like he was just pressing for the win. And he got it. He had better play, and no he didn't have to promote to a B, but if we assume it was the fastest path to victory he saw, it's ok. |

| Jun-09-24 | | FM David H. Levin: Taking nothing away from Black's concept, 18.Bf1 (after 17...Nh4) seems a tougher nut to crack. 
click for larger viewFor example, 18...Qg4 19.Bd2 Bd5 20.Qg3, and 20...Qxd4 would lose to 21.Bc3 Nf3+ 22.Qxf3. Or 18...Qg6 19.Bf4 Bd5 20.Bg3 Nf5 21.Bd3. Although I believe that Black might be somewhat better after 18.Bf1, leveraging this enough for a win seems problematic. |

A strange chess puzzle.
Stockfish 16.1 says Black to move and lose:
16. .. Qh5
(16. .. Qh5 (1. ... Qh5 2.Qxc3 Nh4 3.Bf1 Bd5 4.Bd2 Qg4 5.Qg3 Qxg3 6.hxg3 Nf5 7.c4 Be6 8.Bc3 h5 9.a4 Rde8
10.Reb1 Kb8 11.Rb2 Rc8 12.Rc1 Rc7 13.Rd1 Rhc8 14.Bd2 Nxd4 ) -0.76/53 681) score for Black -0.76 depth 53. |

| Jun-09-24 | | Cecco: This is a new frontier for the insane puzzle. You are asked to predict, a few moves in advance (two, in this case), which plausible, but actually wrong, move your opponent may find himself playing, following which a winning combination exists. If an amateur knows that the puzzle can work this way, the solution is insane. If he doesn't know, it's impossible. |

 | | scormus: Unusual puzzle. It didn't seem too difficult to pick the text moves for B, admittedly with a bit of help from W. But what to play when it gets to move 24 .....? Surely B doesn't allow 25 Qxf7 and 26 Rc7+, can he? OMG he does! SF16 agrees that B wins from here, whatever W plays. I didn't get that. Kudos to B, cool play. |

 | | Honza Cervenka: I guess that the puzzle should have started from 18...Nxg2. I am glad that I have figured out quickly that 16...Qh5 17.Qxc3 Nh4 is the best continuation for black but I was unable to find any advantage after 18.Bf1. |

| Jun-09-24 | | daveinsatiable: This is why I'm just an average club player – I completely convinced myself and was about to post that black has a much easier win at move 19 with:
19. ... Bh3+
20. Kg3/h1 is mate in 1/2 respectively and 20. Kg1 allows 21. Qf3, which forces white to move his WSB, and thus give up his queen, to prevent mate on g2. Except that 21, Bf5 is check, and black instead loses his queen and the game. |

 | | LIFE Master AJ: Yeah. White's 18. Bf4 looked suspect to me as well. I did find Black's ...Qh5 & ...Nh4, but after Bf1, I was stumped just analyzing from the diagram. |
|

| | LIFE Master AJ: Still, it was an interesting puzzle. |

 | | Yuridmi: 18. Bf1 is even
Hey why not, I'm always looking for a "cook" in these puzzles |

| | scormus: <daveinsatiable> Sometimes the avrage club player can hit upon something the others miss.
In your line, if 21. Qg4+ instead of Qf3, wouldn't that avoid the 22 Bf5+ problem? Surely it will go similar to the game itself and end up winning, right? I checked with SF which says I'm half-right. Yes, it goes pretty much the same. And no, it doesn't win. I didn't "get" as much of this puzzle as I thought. So, where's the catch? <FM David H. Levin>, anybody? |

| Jun-09-24 | | King.Arthur.Brazil: The king picked other line: 16...Qd5 17. Qxc3 Nh4 18. Bf1 Bh3 19. gxh3 Nf3+ 20. Kh1 Nxe1+ 21. Kg1 Nf3+ 22. Kh1 Nh4+ 23. Kg1 Rde8. But, it is not a promise to win. |
