| Feb-12-23 | | lentil: I got the first two moves, but that was all. |
|
| Feb-12-23 | | Brenin: Black's control of the a8-h1 diagonal suggests 24 ... Re1 25 Rxe1 Qxf3 26 Qg5 Ng4. White seems have done all he could to defend himself until the horrible blunder 32 Kf2, allowing the royal fork Ne4+. However, the R was pinned and either Nd5 or Ng4 was coming, so White was lost. |
|
| Feb-12-23 | | eaglewing: What's wrong by defending with 25. Nxe1 ?
My impression is: Both sides would lose Queen and Rook and then it should be drawish. |
|
| Feb-12-23 | | Brenin: <eaglewing: What's wrong by defending with 25. Nxe1 ?> Then 25 ... Ng4 threatens both Nxh6 and Qh1 mate, so it wins White's Q. |
|
| Feb-12-23 | | Allderdice83: 32. Kf2 loses the queen, but nothing is very good there. 32. Qg3 Ng4! and the rook falls (33. Qxg4?? Qxe3#). However, what about 25. Nxe1 instead of Rxe1? Say 25 ... Qh1+ 26. Kf2 Ng4+ 27. Kg3 Nxh6 28. Rxh1 Bxh1 29. fxg6 fxg6 and material is equal. Or 25 ... Qxd4+ 26. Rf2 Ng4 27. Qf4 and White will be up a piece in the endgame. |
|
| Feb-12-23 | | jrredfield: I went with 24 ... Ne4 which only leads to a draw after 25 fxg6 hxg6 26 c4. Guess I was looking for a quick tactical gain when considering 24 ... Re1 when the real value of that move is preparing a killer attack on the White K. Not a great week for me. |
|
| Feb-12-23 | | sudoplatov: This was relatively easy. 24...Re1 seems good. Neither capture helps. All that need checking (so to speak) is that White's 26.Re8+ and later f6+ don't work. |

 | | scormus: Thinking ..... Easy start, but the hard move to decide on is 26 ....
W's check sequence looks rather dangerous after ... Ng4. What about .... Qh8+? No, that doesn't seem to come to anything, so bite the bullet with Ng4 and hope BK can escape to safety. OK, it worked out in the game, but is it sound?Check with SF now. |

 | | Sally Simpson: 
click for larger viewI went with the first few obvious moves, Rook sac take on f3, Qg5 and Ng4 but got as far as Re8 + and then I saw f6+ OOPS! (which happened in the game, too far in, I missed the backward Knight move taking on f6). Could not see anything else. Tried to get the King onto f2 so I could play Ng4+check and pick up the Queen on h6. (fail). So gave up. |

| Feb-12-23 | | agb2002: The white knight blocks the action of the black pieces and protects d4. This suggests 24... Re1: A) 25.Nxe1 Qxd4+ (25... Qh1+ 26.Kf2 Ng4+ 27.Kg3 Qxf1 28.Bxf1 Nxh6 29.fxg6 does not achieve anything) 26.Rf2 Qxf2+ 27.Kxf2 Ng4+ and 28... Nxh6 wins a pawn. B) 25.Rxe1 Qxf3
B.1) 26.Qd2 Qh1+ 27.Kf2 Qxh2+ 28.Kf1 (28.Ke3 Ng4#) 28... Qxd2 wins decisive material. B.2) 26.Re2 Qh1+ 27.Kf2 Ng4+ and 28... Nxh6 wins decisive material. B.3) 26.Bf1 Qh1+ as in B.2.
B.4) 26.Qg5 Qh1+ (26... Ng4 27.Re8+ Kg7 28.f6+ Nxf6 29.Qg3) 27.Kf2 Qxh2+ B.4.a) 28.Kf1 Bf3 (28... h6 29.Qg1 Qh3+ 30.Ke2)

B.4.a.iii) 29.Re7 Qh1+ 30.Kf2 Ng4+ 31.Kg3 Qg2+ 32.Kf4 (32.Kh4 Qh2#) 32... Qd2+ 33.Kf3 Qxg5 wins decisive material. B.4.a.iv) 29.Rc1 Ng4 30.Qd8+ Kg7 as in B.4.a.i.
B.4.b) 28.Ke3 Nd5+ 29.Kf3 (29.Ke4 Qf2 looks winning -30.Qd8+ Kg7 31.f6+ Nxf6#-) 29... f6 (29... Nf4+ 30.Be4) B.4.b.i) 30.Qg1 Qf4+ 31.Kg2 (31.Ke2 Nc3#) 31... Ne3+ 32.Kh3 Bg2+ wins decisive material.

Nxe1 seems to win a pawn at least. B.4.b.iv) 30.Re8+ Kg7 31.Qc1 (else as above) 31... Nc7+ wins decisive material. C) 25.Nh4 Qh1+ 26.Kf2 Rxf1+ 27.Bxf1 Ng4+ wins decisive material. |

| Feb-12-23 | | agb2002: I overlooked 29... Nxe8 in the subline to my line B.4. I've known better weeks. |

 | | Fusilli: I got 24...Re1 quickly, not because I calculated marvelously (I didn't) but because it looked like an exposed king and a brutal bishop on the long diagonal guaranteed easy compensation with attack. I think the main challenge of the puzzle is to note the power of the pin on the dark squares. I only thought of 29...Qh1+ and capturing the h2 pawn with check, which is surely ok. But 29...Qd1+ is the killer. |
|
| Feb-12-23 | | sfm: The exchange sac 24.-,Re1 was something we should have been able to decide for, on a good day.
White is clearly in deep trouble.
Hopefully we'd have ended with finding the pretty and strongest move 31.-,Qa7!
That keeps the queen out of reach of the c-pawn, while White after 31.-,Qb6(?) 32.c4,h6 33.c5 is ever-so-slightly better than after 31-,Qa7. Though not by much. |
|
| Feb-12-23 | | Brenin: <agb2002>: A) 25 Nxe1 Ng4, threatening the Q on h6 and mate on h1, is much stronger than 25 ... Qxd4+. |

 | | Check It Out: Like others, I found 24...Re1 25.Rxe1 Qxf3 easily. Committing to that in a live game would be tough though, as I couldn't sort out the many branches to follow. |
|
| Feb-13-23 | | King.Arthur.Brazil: I saw the POTD in the evening, but I was to sleepy to think. However, now, I look into it and I wonder that would be 24... Re1 because of the tittle. If it was Monday, my answer would be the same, because there's no decisive move like this one. The cherry is that after 25.Nxe1 Ng4 and White cannot stop 26... Qh1# without lose the ♕, (the King loves it, you know...). The continuation 25. Rxe1 Qxf3 26. Be4 doesn't help too, since 26... Bxe4 27. Qg5 Ng4 and White must lose the ♕ too. I frankly believe that White must neutralize Blacks ♗ of b7, before opening his King side to attack. This weakness is much more dangerous, than the proposed attack to punish Black. |
