Jun-08-17  Cheapo by the Dozen: Pretty easy one IF, at the points where Black is down only exchange for pawn and still has an attack, you just assume with Spielmannesque faith that that's a good position and turn your calculations elsewhere.

  al wazir: I thought 22. Bh5 gave white better chances. After 22...Bf4+ 23. g3 I didn't see a win.
Jun-08-17  ChemMac: <al wazir> 22. Bh5 RXh5+ 23.QXh5 Bf4+ with Q+B for two R's.
Jun-08-17  RKnight: <al wazir> After 22 Bh5 Rxh5+, 23 Qxh5 Bf4+ g3, 24 Qxh5+ winning for black, albeit not as convincingly as in the game line.

  al wazir: <ChemMac> & <RKnight>: Thanks. I should have seen that.
Jun-08-17  Walter Glattke: Bh4 is the key, I could solve this myself then, A) 25.Kd4 c5# B) 23.Kf4 Qg5+ 24.Kf3 Qf5+ as A) one move later
C) 22.Bh5 Bf4+ 23.g3 Rxh5+ 24.Qxh5 Qxh5+
25.Kg2 less worse continuation so far
Jun-08-17  Walter Glattke: D) 22.Rh5+ (RKnight) Qxh5 23.Bf4+ seems better
D2) 22.Kg3 leads to A)
C) always C2) 22.-Bf4+ 23.g3 Rxh5+ 24.Kg2 Rg5 25.Qf3 Rxg3+ 26.Qxg3 Bxg3 27.Kxg3 Qxc4 C3) 25.g4 Ne5 26.Kh3 Rxg4
27.Qxg4 Nxg4 28.Kxg4 Qxc4
Jun-08-17  mikealando: "Here's Johnny!"
Jun-08-17  stacase: Way too easy for a Thursday.
Jun-08-17  newzild: <al wazir> At least you're honest.
Jun-08-17  morfishine: Rook reloader <20...Rxh2+> followed by <21...Rh8+>

*****

Jun-08-17  offramp: I saw 20...Rxh2+ quickly but I followed up with ...Bf4+. I suppose that wins as well.
Jun-08-17  Walter Glattke: offramp, you lose with 20.-Rxh2+ 21.Kxh2
Bf4+ 22.g3 Rh8+!? 23.Kg2
Jun-08-17  Walter Glattke: 22.-Qg5 23.Qf3 Ne5 24.Qxf4 Ne5 25.Bxe6+ Kc7 26.Qxf4 Rd2+ 27.Ne2
Jun-08-17  Walter Glattke: Ah mistake, 24.Bxe6+ Kc7 25.Qxf4 Rd2+ 25.Ne2
Jun-08-17  saturn2: Black has to prove the investment of the rock pays off and the king cannot escape to the queenside. Everything goes with check Rh2,Rh8,Bh4,Qf5.

  thegoodanarchist: Not a good Thursday, IMO.

Anyone who has solved at least 17 chess puzzles in the last decade can immediately see that 20...Rxg2+ MUST be played, lest the gods of tactics be offended.

Jun-08-17  Walter Glattke: That's right, white threatens Qxe6 or Ne5, we need an "unbroken/instant check chain with finally mate", that ALWAYS wins! LOL
Jun-08-17  jrredfield: Easiest puzzle of the week for me. I got it even faster than Monday's puzzle.

  kevin86: very easy-the sacrifice was obvious!
Jun-08-17  Ninja702: Rh2 cries out but i was unsure of the mating path. Saw Bh4 but couldnt see the board well in my head beyond that.

  agb2002: The material is identical.

White threatens Bxe6 and Ne4.

The obvious move is 20... Rxh2+ 21.Kxh2 Rh8+:

A) 22.Bh5 Rxh5+ (22... Bf4+ 23.g3 Rxh5+ 24.Kg2 unclear)

A.1) 23.Qxh5 Bf4+ wins decisive material (24.g3 Qxh5+, etc.).

A.2) 23.Kg3 Bh4+

A.2.a) 24.Kh2(3) Bf2+ 25.Qxh5 Qxh5#.

A.2.b) 24.Kg4 Qf5#.

A,2.c) 24.Kf3(4) Qf5+ 25.Ke3 Bg5+ 26.Kd4 c5#.

B) 22.Kg3 Bh4+ is similar to A.2.

Jun-08-17  mel gibson: That was very easy.
The computer says:

20. Kh1 Rxh2+ (20. .. Rxh2+ (♖h8xh2+ ♔h1xh2 ♖d8-h8+ ♗f7-h5 ♖h8xh5+ ♕e2xh5 ♗g5-f4+ g2-g3 ♕c5xh5+ ♔h2-g2 ♕h5-g6 ♘c3-e2 ♗f4-d2 ♘e2-c3 ♗d2xe1 ♖a1xe1 ♘d7-b6 ♘c3-e4 ♘b6xc4 b2-b3 ♘c4-e5 ♘e4-f2 ♕g6-h5 ♖e1-e3 ♘e5-d7 ♔g2-f1 ♕h5-d5 ♖e3-e2 ♘d7-e5 ♖e2-e3 ♕d5-d4) +7.82/19 185)

score for black +7.82 depth 19

Jun-08-17  Nova: White had the initiative through the entire game until 20…Rxh2+! came thundering down on the board.

Surprising considering how quickly that turned!
