Jan-25-23  YoungEd: Score one for the YoungEd express! Got it pretty quickly.
Jan-25-23  Honey Blend: 21. ♕xd6 is just absolutely giving it up, although 21. ♘d2 ♗c5 will still lead to a crushing attack.
Jan-25-23  mel gibson: Yes - I saw that same move as the text 20... Qe3

Stockfish 15 chose a different move:

20...Rd8

(20. .. Rd8 (♖e8-d8 ♘b1-d2 ♗d6xf4 ♖a1-e1 ♗f4xd2 ♕d5xd2 ♕b6xb5+ ♕d2-e2 ♕b5-f5+ ♔f1-g1 ♕f5-c5+ ♕e2-e3 ♕c5xe3+ ♖e1xe3 b7-b5 ♔g1-f2 ♖d8-b8 ♔f2-f3 f7-f6 ♖e3-b3 ♔g8-f7 ♔f3-e3 b5-b4 a3xb4 a5xb4 ♔e3-d4 ♔f7-e6 g3-g4 ♔e6-f7 ♔d4-c5 ♔f7-g6 ♔c5-c6 h7-h5 ♔c6-c7 ♖b8-b5 ♔c7-c6 ♖b5-g5 g4xh5+ ♖g5xh5 ♖b3-g3+ ♔g6-h6 ♔c6-d7 ♖h5xh2 ♔d7-e6 g7-g6) +7.46/36 109)

score for Black +7.46 depth 36.

However -
when I force SF to play the text move it is a better score:

20. b5 Qe3
21. Nd2

(21. Nd2 (♘b1-d2 ♗d6-c5 ♔f1-g2 ♕e3-f2+ ♔g2-h3 ♖e8-e2 ♘d2-f3 ♕f2-g2+ ♔h3-g4 ♖e2-f2 ♖a1-e1 ♕g2xf3+ ♕d5xf3 h7-h5+ ♔g4xh5 ♖f2xf3 ♖e1-e8+ ♔g8-h7 a3-a4 b7-b6 ♔h5-g5 ♖f3-d3 ♖e8-e1 ♖d3-d5+ ♔g5-g4 ♖d5-d4 ♖e1-a1 g7-g6 ♔g4-f3 ♔h7-g7 ♖a1-a2 f7-f5 ♔f3-g2 ♔g7-f6 ♔g2-f3 ♔f6-e6 ♖a2-e2+ ♔e6-f7 ♖e2-a2 ♖d4-e4 ♔f3-g2 ♔f7-e6 ♔g2-h3 ♖e4-d4 ♔h3-h4 ♔e6-f7 ♔h4-h3 ♔f7-f6 ♔h3-g2 ♔f6-e6 ♖a2-a1 ♔e6-d5 h2-h4 ♔d5-e6 ♔g2-h3 ♔e6-f6 h4-h5 g6xh5 ♖a1-a2 ♖d4-d3 ♖a2-e2 ♖d3-a3 ♖e2-e8 ♖a3xa4) -8.62/45 183)

score for White -8.62 depth 45.

Jan-25-23  Brenin: 20 ... Qe3 makes a nice finish, e.g. 21 Nd2 Bc5 22 Kg2 Qf2+ 23 Kh3 Re2 24 Nf3 Qg2+ 25 Kg4 Rf2. However, Black missed a quicker finish with 18 ... Re1+, e.g. 19 Kxe1 Bb4+ 20 axb4 Qxd5.
Jan-25-23  Mayankk: I saw the potential of 20 ...Qe3 and how 21 Qxd6 Qf3+ Kg1 22 Re1# leads to immediate ruin.

However I spent some time figuring out what to do if 20 ... Qe3 21 Nd2 Bc5 22 Qg2. I then saw the rather obvious 22 ... Qd3+ 23 Qe2 Qxe2# and was satisfied that there are no complex side-lines.

Jan-25-23  jrredfield: I chose 20 ... Bxf4, thinking to further decimate White's King safety and get something in return for losing the Bishop. Not a bad move: 21 gxf4 Rd8 22 Qc4 Rd1+ 23 Ke2 Rd4 24 Qc8+ Rd8 25 Qc3, giving White about a 4 to 5 pawn advantage. However, the two moves <mel gibson> analyzed are superior. Black has several other paths to victory, or at least somewhat of an edge: Bb8, Rd8, Bf8, seems like Black can't go wrong.
Jan-25-23  BxChess: I went with 20...Rd8, and was relieved to see that <Mel Gibson's> SF analysis also prefers it.
Jan-25-23  Mayankk: Hi <Brenin>

After 20 ... Qe3 21 Nd2 Bc5 22 Kg2 Qf2+ 23 Kh3 Re2 24 Nf3 Qg2+ 25 Kg4, 25 ... Rf2 may run into 26 Qxc5 Qxf3+ 27 Kh3 when White has to guard against back-rank threats. Instead 25 ... h5+ forces the White King to move out of g4-h3 hiding space and then either Qh3+ or Be7+ leads to an easier mate I think.

Jan-25-23  Allderdice83: I saw 20 ... Qe3, but then after 21 Qxd6?? incredibly I came up with 21 ... Qe1+. Amazingly, it still works: 22 Kg2 Re2+ 23 Kh3 Qf1+ 24 Kg4 h5+ 25 Kg5 Qh3 26 Qd8+ (or Qb8+) Kh7 and Qg4# is coming. Alternatively,

25. Kxh5 Qh3+ 26. Kg5 f6+ 27. Kg6 Qg4#

24. Kh4 Rxh2+ 25 Kg4 Qe2+ followed by Rh5#

Other lines are similar.

Jan-25-23  Brenin: Thanks, <Mayankk>. 25 ... h5+ can be answered with 26 Qxh5, and Black is running out of attack. After 25 ... Rf2 26 Qxc5 Qxf3+ 27 Kh3, I think that 27 ... Qg2+ wins, e.g. 28 Kh4 Qxh2+ 29 Kg4 g6, avoiding the back-rank mate and threatening h5+, or 28 Kg4 h5+ 29 Kf5 Re2, with Qe4+ and Qh3+ both threatened.
Jan-25-23  saturn2: Two white pieces are useless in the corner. First instinct was 20. ..Qe3 21.Qxd6 Qf3 But 21.Nd2 is more complicated.

I also looked at the the tame 20....Rc8 threatening Rc1 and Rc5 winning a pawn. But this cannot be a puzzle move.

Jan-25-23  saturn2: I am surprisd a grandmaster plays 16.Bxd5 opening the e file against the king in the middle. Only patzers and grandmasters make such moves.
Jan-25-23  murkia: Monday Wednesday,Tuesday Monday, Wednesday Tuesday.
Jan-25-23  AlicesKnight: ... Qe3 looked good but I expected White to do something more helpful than capture the B.
Jan-25-23  TheaN: It's kind of obvious Black can play <20....Qe3!> without penalty: the point being the text 21.Qxd6? Qf3+ 22.Kg1 Re1#.

Instead, 21.Qd2 Qf3+ 22.Qf2 (Kg1 Bc5+ #1) Qd1+ 23.Kg2 Re2 -+, and the more logical <21.Nd2 Bc5 22.Kg2> looks is terrible: I hadn't really analyzed it, but Black improved the position and is winning after <22....Qf2+ -+>.

Jan-25-23  Allderdice83: <After 20 ... Qe3 21 Nd2 Bc5 22 Kg2 Qf2+ 23 Kh3 Re2 24 Nf3 Qg2+ 25 Kg4, 25 ... Rf2 may run into 26 Qxc5 Qxf3+ 27 Kh3 when White has to guard against back-rank threats. Instead 25 ... h5+ forces the White King to move out of g4-h3 hiding space and then either Qh3+ or Be7+ leads to an easier mate I think.>

25 ... Rf2 is fine. After 26 Qxc5 in the above line, there is 26 ... h5+ 27. Qxh5 Qxf3+ 28. Kh4 Rxh2+ or 28. Kg5 f6+.

More dangerous is 26. Re1 Qxf3+!

(not 26 ... h5+?? 27. Kh4 Qxf3?? 28. Re8+ Kh7 29. Qf5+ g6 30. Qxf7+ Kh6 31. Rh8#)

27 Qxf3 h5+ 28. Kxh5 Rxf3 with a winning endgame.

  FSR: I also went with 20...Qe3 and, like others, expected White to try something more intelligent than 21.Qxd6 (="Resigns").

  agb2002: Black has a bishop for a knight.

Black can increase the pressure on White's field with 20... Qe3 (20... Bxf4 21.gxf4 Qf6 22.Ra2 Qxf4+ 23.Rf2 Qc1+ 24.Kg2 Qxb1 25.Qxf2+ Kh8 26.Qxe8#):

A) 21.Qxd6 Qf3+ 22.Kg1 Re1#.

B) 21.Nd2

B.1) 21... Bc5

B.1.a) 22.Qg2 Qd3+ 23.Qe2 Qxe2#.

B.1.b) 22.Ne4 Rxe4 23.Qd8+ Bf8 - + [b].

B.1.c) 22.Kg2 Qf2+ (another option is 22... Qe2+ 23.Kh3 Qxb5 24.Ne4 b6) 24.Kh3 (24.Kh1 Re2 25.Nf1 Qg1#) 24... Re2 25.Nf1, unclear.

B.2) 21... Bxa3 seems to win a pawn

B.2.a) 22.Qxb7 Qxd2 23.Rxa3 Qc1+ and 24... Qxa3.

B.2.b) 22.Nc4 Qe2+ 23.Kg1 Bb4 24.Nxa5 Bxb5 25.Rxa5 Qe1+ and 25... Qxa5.

C) 21.Kg2 Bxf4 22.gxf4 Qe2+

C.1) 23.Kh1 Qf1#.

C.2) 23.Kg1 Qe1+ 24.Kg2 Re2+

C.2.a) 25.Kf3 Qf1+ (better than 25... Qh1+ 26.Kxe2 Qxd5) 26.Kg3(4) Qg1+ and mate soon (27.Kf3 Re3#; 27.Kf5 Qg6#; 27.Kh3(4,5) Rxh2#; 27.Qg2 Qxg2+ etc.).

C.2.b) 25.Kh3 Qf1+ 26.Kh4 (26.Kg3(4) transpose to C.2.a) 26... Qxf4+ 27.Kh3(5) Rxh2#.

C.3) 23.Kg(h)3 Re3+ 24.Kh4 Qxh2+ 25.Kg4(5) Qg3+ 26.Kh5 (26.Kf5 Qg6#) 26... g6+ 27.Kh6 Qh4#.

Jan-26-23  Halldor: My first guess was 20 Rd8, but quickly abandoned it as I couldn't find a forced continuation. — Then I saw 20.Qe3, and after seeing that White can't take the bishop — it's an instant curtain, I was convinced I was on the right track.

I examined 21 Nd2 / Ra2 / Qd2. It was fun and leads to mate in many lines I thought, at least great attack from Black. — Sadly Fishbein didn't play any of that which would have allowed fireworks from Black to entertain the crowd.
