  OhioChessFan: Thanks <Minty> That e3 check is the fly in the ointment. It comes up in 3 different lines I tried.
Oct-07-06  ksh123: Wonderful finish! There was no escape for Black after 20 Qe6+.
Oct-07-06  pawntificator: That was awesome.

  Jonathan Sarfati: Just a hint for some of these long combinations: sometimes it's good enough to make sure there is an escape route. Even Kasparov during his "immortal against Topalov Kasparov vs Topalov, 1999 said it was not all calculated from the start, but he knew he could bail out with a perpetual if he couldn't see something more a few moves on. In this game, it would be reasonably safe to see that White gains R+N+P+attack for the Q, even though Bc5+ is not too onerous to see from the start.
Oct-07-06  midknightblue: hello pawntif. The first move seemed inevitable-if the finish could be calculated. tough problem, well done to all that had the line calculated to perfection

  kevin86: A great finale! White sacs the queen to open up lines and diagonals for his bishops and rooks. There is no escape!
Apr-05-08  ToTheDeath: Amazing finish. Kova was an animal.
Nov-29-12  Wyatt Gwyon: lol. You could see the storm brewing from about move eight or nine.
Jan-31-21  ndg2: Not insane, not even very difficult, IMHO
Jan-31-21  sudoplatov: I found this one quickly by looking for a method of unscreening the White Rooks. Qe6+ then Be6+ uncovers the White h1 Rook (I assume it's the King's Rook but they both look alike.) Then Bxh6 and Rxh6+ become possible. Black's King seems rather cramped.
Jan-31-21  Walter Glattke: This is a criminal constellation, where the White pokerface in coffeehousss or bistros plays bd3/be3/qd2/0-0-0/rg1/rh1 and the landegg has to play "encyclopaedia" waiting moves like nf6/g6/0-0 qc7/a5 to get looted then for a hypothek of his fathers acre. 20.Bxh6 wins, the specticular queen sac with 20.Qe6 is not credible and shows, how manipulated this alcohol constellation really is.

  An Englishman: Good Evening: Amazed to have solved it but then realized had written the same thing in 2006. Weird week--4/4, already knew Friday, Saturday, Sunday.
Jan-31-21  Brenin: Declining the Q is no help for Black, e.g. 20 Qe6+ Kh8 21 Bxh6 Bf6 (21 ... Nxe6 22 Bxe6) 22 Bd2, with mate along the h-file to follow.
Jan-31-21  Brenin: My first attempt, the routine 20 Bxc5 Bxc5 21 Qe6+ Kh8 fails, e.g. 22 Bf5 Rd6: the White Q is trapped, and the Black Q protects g7, so 23 Rxh6+ loses to gxh6 24 g7+ Qxg7.
Jan-31-21  ndg2: <Walter Glattke: This is a criminal constellation,..> Lol, this is good!

  agb2002: White has the bishop pair for a bishop and a knight.

A quick scan yields 20.Qe6+ Nxe6 21.Bxe6+ Kh8 22.Bxh6 gxh6 23.g7+ Kh7 24.gxf8=Q Bxf8 25.Bg8+ Kh8 26.Rxh6#, a faulty line but it invites to carry out a more detailed analysis. So 20.Qe6+:

A) 20... Nxe6 21.Bxe6+

A.1) 21... Kh8 22.Bxh6 gxh6 (due to Bg5#) 23.g7+ Kh7 24.g8=Q+ Rxg8 25.Bf5+ Rg6 (25... Kh8 26.Rxh6#) 26.Rxg6 Bf8 27.Rxc6+ and 28.Rxc7 wins decisive material.

A.2) 21... Rf7 22.gxf7+

A.2.a) 22... Kh8 23.Bxh6 wins.

A.2.b) 22... Kh7 23.Bf5+ g6 (23... Kh8 24.Bxh6 as above) 24.Rxg6 Bf8 25.Rg8#.

A.2.c) 22... Kf8 23.Rxh6

A.2.c.i) 23... Bd6 24.Rh8+ Ke7 25.Bg5+ Kxe6 26.Bxd8 Qd7 27.f8=Q Bxf8 28.Rxf8 + - [2R+B vs q].

A.2.c.ii) 23... Bf6 24.Bc5+ Nd6 25.Rh8+ Ke7 26.Rh8+ Ke7 27.Rxd8 Qxd8 (27... Kxd8 28.Rd1 wins decisive material) 28.Bb3 followed by Rd1 seems to win decisive material.

B) 20... Kh8 21.Bxh6

B.1) 21... Nxe6 22.Bxe6 transposes to A.1.

B.2) 21... Rf6 22.Bg5 wins (22... Rxe6 23.Bxe6#).

  chrisowen: Ide think it is aloof e6 queenie dear a quick dabble ditto no.
Jan-31-21  Hercdon: Odd, at move 19 Stockfish evaluates the position as even but a half-move later evaluates as 4.29
Jan-31-21  Refused: 20.Qe6+ has to be the solution
20...Nxe6 21.Bxe6+ Rf7 22.gxf7+ Kf8 23.Rxh6 Bf6, up to that point, things were pretty straightforward. Now I struggled a bit to find 24.Bc5+ Nd6 after that things are relatively streaightforward again 25.Rh8+ Ke7 26.Rxd8 Qxd8 27.Rd1 Kxe6 28.Rxd6+ Qxd6 29.Bxd6 Kf7 +-
Jan-31-21  RandomVisitor: 18...h6 would likely be an even game:

Jan-31-21  rbhgroup: nice game... I spotted Qe6 (what else could it be?) but then out-smarted myself by opting for capturing on f7 with the bishop instead of the pawn... (although I did see g:f7 as a possibility)... so near, yet so far...
Jan-31-21  mel gibson: I saw that option of a Queen sacrifice
but I wasn't sure if it would work out OK.
