  al wazir: My line was the queen sac:

38...Qxh4+ 39. gxh4 Rxg2+ 40. Kh1 (40. Kh3 Nxf4+ 41. Nxf4 R8g3#) Rxe2 41. Qxe2 Ng3+ 42. Kh2 Nxe2.

  al wazir: 18...Bxf5 seems to win a ♙: 19. Qd1/Qd2 Bxc2 20. Qxc2 cxb4 21. axb4 Rxc4.

But then we would have missed some nice tactics.

Apr-16-21  Walter Glattke: 38.-Qxh4+ 39.gxh4 Rxg2+ 40.Kh1 Rxe2 41.Rxh7+ Kxh7 42.Qa7+ Ng7 43.Qc7 Rxa2 or 41.Qxe2 Nf3+ 42.Kg2 Nxe2

  drollere: i looked at <al wazir's> Qxh4+ first of all. i did not see an immediate mate for the sacrifice after Qb6. i missed the line by <refused> that plays Rg4 instead, very pretty.
Apr-16-21  Anjeneyar: The most elegant line is:

38...Qxh4+ 39. gxh4 Rxg2+ 40. Kh3 R8g3+ 41. Nxg3 Nxf4#

  Breunor: Found Qxh4, I’m not sure I would have the guts to play OTB. But I feel good at getting this, I missed some of the easy puzzles this week!
Apr-16-21  Brenin: My choice was 38 ... Qxh4+ 39 gxh4 (otherwise White loses a second P on g3) Rxg2+ 40 Kh1 (or Kh3) Rxe2, and if 42 Qxe2 then 42 ... Ng3+ (or Nxf4+) wins the Q, leaving Black ahead by N+P with a passed e-pawn. Other White 42nd moves allow Black a mating attack, e.g. by R8g2.
Apr-16-21  Abdunnaser: 51 Qf2 52 Kc1 Rxh1# is faster
Apr-16-21  malt: Like the look of 38...Qh4+ 39.Kg1

(39.gh4 R:g2+ 40.Kh1 R2g4 41.Ng1 R:h4+ 42.Qh2 Ng3+ 43.Kg2 Ne2+ 44.Kf1 R:h2 )

[40.Kh3 Nf4+ 41.N:f4 R8g3# ]

39...R:g3 40.N:g3 N:g3 Δ 41...e3
41.Kf2 Ne2+ 42.Kf1 Qh1+ and 43...R:g2+

Apr-16-21  mel gibson: Black's move as per the text is a blunder.

I saw the right solution and Stockfish 13 agrees:

38... Qxh4

(38. ..
Qxh4+ (♕f6xh4+ g3xh4 ♖g6xg2+ ♔h2-h1 ♖g2-g4 ♖b7xh7+ ♔h6xh7 ♕b2-b7+ ♖g8-g7 ♕b7xg7+ ♔h7xg7 ♔h1-h2 ♔g7-g6 ♘e2-c3 e4-e3 ♘c3-e2 ♘h5xf4 ♘e2-g1 ♖g4-g2+ ♔h2-h1 ♖g2-f2 a3-a4 ♔g6-h5 ♘g1-h3 ♔h5xh4 ♘h3xf2 e3xf2 ♔h1-h2 ♔h4-g5 ♔h2-g3 f2-f1♕ ♔g3-h2 ♕f1-g2+) +M17/89 141)

score for Black mate in 17.

Apr-16-21  njchess: I chalk this up to time control pressure. After all, it IS a Queen sac. There are a lot of moving pieces to this position. I mean, with accurate play on White's part (and Black for that matter), per <mel gibson> Stockfish came back with mate in 17, after 15 moves! Not at all realistic OTB.

I think it was a combination of the placement of White's knight and king that threw her. 38. ... ♕xh4+!? 39. gxh4 ♖g2+ 40. ♔h1 ∞ or maybe ⩱. Or perhaps the best way to put it, unclear enough not to sac the Queen. Once White plays 46. ♔g2??, she pounces.

Besides, it is a rapid match...

  agb2002: White threatens Qxf6 followed by Ra7.

The black rooks x-ray g2. This suggests 38... Qxh4+:

A) 39.gxh4 Rxg2+

A.1) 40.Kh3 Nxf4+ (or 40... R8g3+ 41.Nxg3 Nxf4#) 41.Nxf4 R8g3#.

A.2) 40.Kh1 R2g4

A.2.a) 41.Nc1(3) Rxh4+ 42.Qh2 Rxh2+ 43.Kxh2 Nxf4 wins three pawns.

A.2.b) 41.Ng3 Rxh4+ 42.Kg1(2) Rxg3+ 43.Kf1 Rh1+ 44.Kf2 Rh2+ 45.Kf1 Rxb2 wins decisive material.

A.2.c) 41.Rxh7+ Kxh7 42.Qb7+ Kh6 43.Qe7 R8g6

A.2.c.i) 44.Qd8 Nf6 45.Qh8+ Nh7 46.Qd8 Kh5 is winning.

A.2.c.ii) 44.Kh2 Nf6 45.Kh3 Kh5 is winning.

B) 39.Kg1 Nxg3

B.1) 40.Qb1 Nxe2+ wins.

B.2) 40.Nxg3 Rxg3 41.Rxg3 Qxg3+ 42.Kf1 Qg1+ 43.Ke2 Rg2#.

B.3) 40.Kf2 Nxe2+ wins.

  agb2002: I can't explain how I missed the extremely simple 42... R8g7 in my line A.2.c.

  OhioChessFan: I just played through the solution and have no clue what was going on.
Apr-16-21  alshatranji: Very interesting. I had 38...Qxh4+ 39. gxh4 Rxg2+ 40. Kh1 Rxe2. But I wasn't sure after 41. Qb6. Stockfish has 41... Rg6 with a won position. More interestingly, Stockfish does not recommend the "beautiful" sacrifice 40...Rxe2, but the more solid (and devastating) 4...R2g4.

  eternaloptimist: Yeah Judit missed combinations just like any other chess player. She is very talented tactically for sure but she’s a human being. I actually saw 38...♕xh4+! but I’ve “flubbed” (a la <An Englishman> many of these CG puzzles over the years. 😃
Apr-16-21  RandomVisitor: After 7...0-0

Stockfish thinks white has a large advantage:

Apr-16-21  King.Arthur.Brazil: When I saw it was a "rapid" game, without analyzing , I first went on 38...♘g3, would be good if didn't have the answer 39.♕xf6+. And this answer frustrated any other move, that don't avoid the ♕ exchange. In other words, Black must move the ♕. So, the King tried the combination: 38...♕xh4+ 39. gxh4 ♖xg2+ 40. ♔h1 ♖xe2 41. ♕xe2 ♘g3+ 42. ♔h2 ♘xe2. The problem is that White need not to capture ♖e2. If White played bad (defensively) with moves like 41.♕b1? (or ♕c1?) then 41...♖gg2 42. ♖b3 ♘g3+ 43. ♖xg3 ♖xg3 and it seems that Black has winning position. However, when White plays correctly 41.♕b6! ♖g6 42. ♕d8} and ♗lack lose the attack (get back with 42...♘f6 and White can survive or revert the situation. Note that 43.♕xd6? cannot be played because of 43...♖h2+! 44. ♔xh2 ♘g4+ 45. ♔h3 ♖xd6, but Black is not winning. Therefore, the move of the text is justified. When I was posting, see the comment of fishouse, but I didn't followed its lines... lgs. (it seems that 40...♖2g4 can win...)
