Stockfish 17 says Black wins _ mate in 23:

May-28-25 | | BxChess: Nice puzzle. The first move 28. ...Nxh2 is sort of obvious since you know it is a puzzle. The move I didn't see from the puzzle position was 31. ...Qf4+, after which comes the payoff. |
|
May-28-25 | | King.Arthur.Brazil: The combination seems simple: 28...Nxh2 (refusing: 29. Rf2? Qxg3+ 30. Kh1 Qxf2 lose the ♖) 29. Kxh2 fxg3+ 30. Rxg3 Rf2+ 31. Kh3 Qh5# or 30. Kg2 Rxf3 31. Kxf3 Qf4+ 32. Ke2 Qf2+ 33. Kd1 g2 34. Nd2 g1=Q+ 35. Kc2 Qgg2 36. Bc1 Qe1 37. Qa8+ Bf8 38. Qd8 Qgg1 39. Bb2 Qd1+ 40. Kc3 Qd4#. Other possibility is 30. Kg2 Rxf3 31. Kxf3 Qf4+ 32. Kg2 Qf2+ (33. Kh1 Qh2#) 33. Kh3 Qh2+ 34. Kg4 g2 and W will lose the ♕. (I love it, did you know?). |

May-28-25 | | King.Arthur.Brazil: <mel gibson> Hi. Have you noticed that since every time you see "fishouse" answers, you're quicker in found the best move than you were in the past? It is surprising how day by day, you're getting more confident in appreciating a position and look at the board more deeply. I guess that many of us are becoming more trained than we have being in all our previous times. In this case, I had to thank to "Fishouse" since it becomes a challenge to anyone to exceed the computer reply. |

 | | takebackok: Yes, easy forced sac wining Wednesday, 28...Nxh2 (lights out) 29. Kxh2 what else (29. Qd1 Nxf3 30. Qxf3 fxg3 31. Qxg3 Qh5 32. Ne3 Qe2+ 33. Kh1 Rf3 34. Qg5 Qxe3) over and out. |
|
May-28-25 | | Walter Glattke: 28.-Nxh2 a) 29.Kxh2 fxg3+ 30.Kg2 (Rxg3 Rf2+ mating) Rxf3 31.Kxf3 Qf4+ 32. Ke2 Qf2+ 33,Kd3 g2 34.Ne3 g1Q -++ b) 29.Bxe5 Nxf3 30.queen sac Bxf4 31.Qd1 Nh4+ 32.Kh3 Rf3 33.Qxf3 Nxf3 -++ |
|
May-28-25 | | Walter Glattke: c) 28.-Ne3+? 29.Nxe3 fxe3 30.Qf1 Bh6 31.Bc1 and now queen sac! 31.- Rxf3 32.Qxf3 e2 33.Bxg5 f1N+ 34.Kf2 Nxf3 35. Bxh6 Nxh2 36.Bg5 but White wins the ending then |
|
May-28-25 | | stacase: 28...Nxh2 White can move his Rook or take the knight. Neither one improves his position. White chose to take the Knight and the rest was a cake walk for Black. As far as I can see: 29. Rf2 fxg3
30. Rxf8+ Kxf8
31. Qd1 Qf4
or some such is more complicated. |
|
May-28-25 | | TheaN: Good Wednesday! Not super difficult, as <28....Nxh2> kind screams out to be played. Black has enough defenders on e5 to avoid a White counterattack and the rook is suffocating. The only safe square 29.Rf2? Qxg3+ -+ is absolute disaster, best is White just giving up the exchange and pawn but Black's rook is perfectly placed. Of course <29.Kxh2> is key, after which <29....fxg3+> decides: 30.Rxg3 Rf2+ -#3 because the queen will always invade over the h-file (or g3 in case of Kg1). Any king move other than Kg2 gives up Rf3 anyway with the attack ongoing, so <30.Kg2>. But now a trade is enough because the king's not a good defender: <30....Rxf3 31.Kxf3 Qf4+ 32.Kg2> after 32.Ke2, the simplest is 32....Qf2+ 33.Kd1 Qf1+ 34.Kc2 Qxa1 35.Bxa1 g2 -+, though 33....g2 directly wins too <32....Qf2+ 33.Kh3 Qh2+ 34.Kg4 g2 -+> and White can't stop g1. |

May-28-25 | | mel gibson: <King.Arthur.Brazil: <mel gibson> Hi. Have you noticed that since every time you see "fishouse" answers, you're quicker in found the best move than you were in the past?> Not really - I still miss quite a few.
OK so Stockfish declined the Knight
and it was mate in 23 -
so what happens if I force SF to accept the Knight? 28. Rf3 Nxh2
29. Kxh2 fxg3+
(29. .. fxg3+ (1. ... fxg3+ 2.Kg2 Rxf3 3.Kxf3 Qf4+ 4.Ke2 Qf2+ 5.Kd1 g2 6.Nd2 g1R+ 7.Kc2 Rxa1 8.Bxa1 h5 9.d4 exd4
10.e5 Bxe5 11.Bb2 h4 12.Bc1 h3 13.Kb3 h2 14.Ne4 Qf3+ 15.Be3 Qxe4 16.Bf2 h1Q
17.Ka3 Qc1+ 18.Ka4 Qec2+ 19.Kb4 Qc4+) +M19/73 276) Black wins _ mate in 19. |

May-28-25 | | TheaN: <King.Arthur.Brazil: <mel gibson> Hi. Have you noticed that since every time you see "fishouse" answers, you're quicker in found the best move than you were in the past? > I digress. Generally, computers have made players lazy, <especially> newer and/or intermediate players. "But computer says +2"... "do you understand why it's +2?", "no", "then it's not +2". However, even GMs (look at current commentary of Norway for example) sometimes misjudge positions entirely based on what the Fish says. As a 1950 teaching 14-16yo right now (some of whom are close to my rating) I fall into this pitfall occasionally when I misjudge a variation: let the computer solve it... in the end it's not an amazing learning tool unless you intend to go over every variation. Reviewing after self analysis is fine: "I assume I was better/worse up to this point... computer confirms or denies that", but IMO not upfront. |

How many iterations are there in 19 moves?
Keeping White's nasty Knight tied up is a chore |
