Aug-25-22  Saniyat24: If one knight doesn't get you, the other knight will...!
Sep-06-24  stacase: 27.Nd5 ... Ah yes the 2nd Knight springs into action. For some reason that reminded me of a line in a well known poem:

And lo! as he looks, on the belfry’s height
A glimmer, and then a gleam of light!
He springs to the saddle, the bridle he turns,
But lingers and gazes, till full on his sight
A second lamp in the belfry burns!

Sep-06-24  mel gibson: I saw that line straight away however Stockfish 16.1 declines the Rook:

24. Rxf6

(24. Rxf6 (1.Rxf6 Qe7 2.Rcf1 Rg8 3.Rh6 Qxh4 4.Rxh4 f6 5.Kg1 h6 6.Rd1 Kh7 7.Kf2 e5 8.Nf5 b5 9.cxb5 axb5 10.Rh3 Bxf5 11.exf5 b4 12.Nd5 Rgc8 13.Rd2 Rb5 14.Rhd3 Rb7 ) +4.58/49 397)

score for White +4.58 depth 49.

If I force SF to accept the Rook:

24. .. gxf6

25. Qxf6+ (25. Nf5 (1.Nf5 exf5 2.Qxf6+ Kg8 3.Nd5 Re8 4.Qg5+ Kh8 5.Nxc7 Rxe4 6.Qf6+ Kg8 7.Qd8+ Kg7 8.Nd5 Be6 9.Qxb8 b5 10.Ne7 Bc8 11.Qxd6 bxc4 12.bxc4 a5 13.c5 f4 14.c6 Bg4) +30.75/39 1108)

score for White +30.75 depth 39.

  LIFE Master AJ: A great problem and a lesson in tactics.

#1.) White sacks the ox on f6. (24.Rxf6!!)
<Why doesn't 24...Qe7 work?>

#2.) 26.Nf5! to clear d5 for the other night.

#3.) With some cute tactics, White sets Blac for the kill.

  scormus: W has the sort of position which I had a habit of messing up by being too eager.

The first 2 text moves looked good, discounting the possibility that B would decline the Rf6. Then I wasn't sure whether 26 Nf5 or Nd5, and my over-eagerness led me to go for Nd5, intending to follow up with 27 Rd3 and 28 Rg3. But according to SF it only draws as the BK wriggles out. Wasn't sure which of 3 promising choices - 28 Ne7+, Qg5+ or Qh6. I fancied the last of those, but it seems they all come out ca. +6 for W after B gives up the Q.

Coming back to 24 ..., the "best" damage limitation move, ... Qe7 seems to concede the game is lost without much of a fight.

Sep-06-24  TheaN: Bit more of an intuitive sac than forcing one, honestly. In this case it's about quantity: Black's queen side, consisting of 4/4 pieces is doing <nothing> compared to White's king side (2/2) all active.

Thus <24.Rxf6 gxf6 (Qe7 25.Rh6 +-, though Rcf1 as well apparently) 25.Qxf6+ Kg8>

After <26.Rf1 +-> I thought we had the classical 2 vs 0 attack advantage. The king alone cannot defend himself, Rf1 prevents the Black queen from moving much due to protecting d8 and f7. Any break in the center is met by a destructive knight move. Were Black to pass, Rf3 > Nf5 > Nd5 is curtains.

I wasn't sure what Black can do here, and neither is SF. Black can try to activate a bit, which are the best moves, but it's too late: 26....d5 27.exd5 e5 28.Nf5 Bxf5 29.Rxf5 Qd6 30.Rg5+ Kf8 31.Qg7+ Ke8:

Black loses e5 and the knight's a monster, 32.Ne4 Qf8 33.Qxe5+ Kd7 34.d6 +- and Black's inactive rooks decide the game in White's favor.

Sep-06-24  Cellist: I also wanted to play 26.Rf1. It is good enough. The engine likes it (+10 for W).
Sep-06-24  Lambda: I was happy with what to do after 27...Qd7 (28.Qh6) but was having difficulty convincing myself of the win after 27...Qa5, avoiding blocking the bishop in or being potentially victim to a knight fork at f6.

  al wazir: I expected 27...Re8.

The continuation would probably be 28. Rc3 Re5/Re6 29. Rg3+ 30. Qh8#.

Sep-06-24  FM David H. Levin: My line started 24. Rxf6 gxf6 25. Qxf6+ Kg8 26. Nf5 exf5 27. Nd5 Qd7, but then it diverged from the game by 28. Qh6 Qe6 29. Nf6+ Qxf6 30. Qxf6 Bd7 31. exf5, reaching a position that would have been similar to the game if Black had played 28...Qxe7.

On 27...Qa5, I reckoned that 28.b4 followed by 29.Qxd8+ had to be winning, given the equal piece material and White's continuing attack.
