Oct-17-15  diagonalley: hmmmm... the themes are fairly transparent, but finding the right move order *AND* spotting the amazing move 21.... R-K6! almost puts this in the 'insane' category
Oct-17-15  rickycota: Any lines after 26.Qh5?
Oct-17-15  Robespierre: For a player of my skill to get the first 4 moves on a Sat puzzle is quite extraordinary (although I believe there was at least a tincture of luck involved!). After that things fell apart.
Oct-17-15  Viennablue: @wildairman: not so sure about this line: how does black continue after 21.Rh3?

  agb2002: The material is identical.

White threatens 19.Rxh4 and 19.Bxa8.

The first idea that comes to mind is 18... Qxh3 19.Bxh3 (19.Bxa8 Ng3+ 20.Kg1 Nxe2+ wins) 19... Bb7+:

A) 20.B(Q)g2 Ng3#.

B) 20.Ne4 Rxh3 21.Kg2 (due to the threat 21... Bxe4+ 22.Qxe4 Ng3+ 23.Kg2 Nxe4) 21... Rd3 with an overwhelming position and the threats Ne3+, winning the knight and Rad8, invading White's field.

C) 20.Nf3 Rxh3 and the double threat Ng3+ and B(R)xf3 seems to win decisive material.

D) 20.Qf3 Bxf3+ 21.Nxf3 (21.Bg2 Ng3#) 21... Rxh3 - + [R].

  morfishine: <18...Qxh3> What else? 18...Ng3+ is flawed
Oct-17-15  abuzic: 18...?
18...Ng3+ loses after 19.hxg3 Qxg3 20.Rxh8+ Ke7 21.Rh3

18...Qxh3 19.Bxh3 Rxh3 20.Kg2 Re3
A. 21.Qd1 Rg3+ 22.hxg3 Ne3+
B. 21.Qh5 Bb7+ 22.Kf1 Rg3
C. 21.Qf1 Bb7+
D. 21.Qf2 Bb7+ 22.Kf1 Rh3 23.Qe1 Rxh2
E. 21.Qg4 Re1 22.Nf3 Bb7 23.h4 0-0-0

19...Bb7+ is another winning alternative

  patzer2: For today's Saturday puzzle solution, I got the obvious 18...Qxh3! with my best guesses following the game continuation all the way through to 21...Re3+! .

However, in checking it out on Deep Fritz 14, it would seem there's a slightly stronger follow-up which is much simpler.

After <18...Qxh3 19.Bxh3>, Deep Fritz 14 indicates the simple and obvious 19...Rxh3 (-5.55 @ 25 depth) is slightly stronger than the nifty game continuation <19...Bb7+ > (-4.64 @ 26 depth).

One computer checked possibility after 18...Qxh3 19.Bxh3 Rxh3 goes 20. Kg2 Re3 21. Qh5 (21. Qf1 Bb7+ 22. Nf3 Bxf3+ 23. Qxf3 Nh4+ 24. Kh3 Rxf3+) 21... Bb7+ 22. Kf1 Rg3 23. Nxc4 Bf3 24. Nd6+ Nxd6 25. hxg3 Bxh5 26. exd6 O-O-O 27. Bd2 Rxd6 (-5.82 @ 23 depth, Deep Fritz 14) when Black's extra Bishop is easily decisive.

P.S.: For an improvement for White, I'd start early in the opening with the Fritz preference 4. Be2 as in G Welling vs I Sokolov, 2009.

Where White's game starts to quickly go down hill is after <10. 0-0?!> which allows 10...c4! . Instead, 10. c3 to defend the d4 square and prepare castling would have improved White's survival chances.

Oct-17-15  PeonNegro: The move 19...Bb7! wins, but 19...Rxh3! is even stronger (wins sooner).
Oct-17-15  dfcx: white is attacking both the rook and the queen, but its own king is cornered.

18...Qxh3 19.Bxh3 (Bxa8? Ng3#) Bb7+ 20.Ne4 Rxh3 21.Kg2 Re3 22.Bxe3 Bxe4+ 23.Kh3 Bxe3

black has three minor pieces against white queen, should be able to win the end game.

  Jimfromprovidence: I was not sure why white resigned after the great 29...Bb7 because after 30 Rxb7 Kxb7, below, material is still roughly equal and white can check on e4.

Then it dawned on me that after 31 Qe4+ Kb8 white cannot defend the mate in one threat ...Be7 without surrendering his queen.

  swordfish: Yeah, I got the first few move (for me, on a Saturday, that's encouraging), but Black finished it off in fine style. I wonder whether he calculated the whole sequence before playing 18...Qxh3.
Oct-17-15  Tiggler: 18.Qxh3 is forced, as is the reply 19.Bxh3, but then 19.. Rxh3 is much better than the game continuation.
Oct-17-15  goodevans: <Jimfromprovidence: ... Then it dawned on me that after 31 Qe4+ Kb8 white cannot defend the mate in one threat ...Be7 without surrendering his queen.>

I looked at that too. Bad enough for white if he can get N+R for the queen but ...Be7 prevents even that! 32.Qxf5 Be7+ and black gets to keep the R.

  Dionysius1: Why so, Tiggler? The move played seems pretty conclusive: does 19Rxh3 achieve something even better or quicker?

Oct-17-15  King.Arthur.Brazil: Following "Jimforprovidence", after forced move: 30. Txb7 - Kxb7, "Goodevans" said that if 31. Qe4+ Kb8, 32.Qxf5 didn't recovers the rook (e6xf5 33.Kxh4) because of 32. ... Be7+ (which defends the black R at h4). But there's a little more: 33.Q-f6 not gxf6+? 34.Kxh4 But 33. ... Bxf6+! 34.exf6 Th7! and now black wins! (laughs)...
Oct-17-15  The Kings Domain: Excellent game by black, he had complete control from the start. Neat finish.
Oct-18-15  Tiggler: <Dionysius1: Why so, Tiggler? The move played seems pretty conclusive: does 19Rxh3 achieve something even better or quicker?>

Good question, so here is a good answer:

Compare the two lines after
19.. Rh3 20. Kg2 (forced) Re3!


click for larger view

and the game continuation
19.. Bb7+ 20. Ne4 Rh3 21. Kg2 Re3!


click for larger view

In the first position the Rook on E3 is invulnerable and sends the white queen running.

Oct-18-15  goodevans: <Tiggler: ... Compare the two lines after 19.. Rh3 20. Kg2 (forced)...>

Is 20.Kg2 really forced? Can't white play 20.Ne4 and doesn't that just transpose?

Oct-18-15  Tiggler: <goodevans> No. After 20.Ne4 0-0-0! is lethal.
Oct-18-15  Tiggler: That line shows that 19.. Bb7+ was a wasted tempo, because the white knight wants to go to e4 anyway.

  CHESSTTCAMPS: Material is even. White skewers the black queen with Rh3, but given white's undeveloped R+B, it is black with the real attack after

18... Qxh3!

Note that 18...Ng3+?? is losing after 19.hxg3 (Rxg3?? Qxh2#) Qxh3+ 20.Bxh3 Rxh3+ 21.Kg2. The knight can be better employed.

19.Bxh3 Bb7+ and now:

A.20.Bg2 Ng3#

B.20.Qg2 Bxg2+ 21.Kxg2 (Bxg2 Ng3#) Ne3+ 22.Kg3 O-O-O and black has an exchange for a pawn with a strong initiative.

C.20.Nf3 Rxh3 21.Kg2 Rxf3 22.Qxf3 Nh4+ wins

D.20.Ne4 Rxh3 21.Kg2 (otherwise Ng3+) Re3! 22.Bxe3 Bxe4+ 23.Kf2 (Kf1 Bd3 wins) Nxe3! (Bxe3+ 24.Ke1 Bd3 25.Qf3 appears to give white counterplay) 24.b4 Nc2+ 25.Kd1 (Kf1 Bd3) Rd8+ 26.Kc1 Be3+ 27.Kb1 Nd4+ wins the queen.

D.1 23.Kh3 Nxe3 (to protect c4) 24.b4 cxb3e.p. 25.axb3 Ke7!! 26.b4 Rh8+ 27.Kg3 Nf5+ 28.Kg4 Rh4+ 29.Kg5 f6+ 30.ef+ gf+ 31.Kg6 Rh6#

Very challenging - time for review.

  CHESSTTCAMPS: In D.1, I was close to the game continuation, but thought 25... O-O-O lost to 26.Qa6+, missing Bb7.
