the White Queen was pinned.

Mar-31-21  Walter Glattke: White Queen is pinned, but it threatens Rh8: 31.Rxg6+ fxg6 32.f7+ Kxf7 33.Rh7+ Kg8 34.Rxd7 Rxe4+ 35.Bxe4 Rc8 1 piece and attack
Mar-31-21  stacase: White needs to say check or lose the Queen. So how many ways are there to do that? And there is more than one, but only one 31.Rxg6+ seems to work. After 31...fxg6 it looks like 32.f7+ gives Black crappy choices all around. Indeed, he throws in the towel.

  agb2002: White has the bishop pair for a knight.

Black threatens Rxe4+.

White can provoke a liquidation of major pieces with 31.Rxg6+ fxg6 (31... Kf8 32.Rh8#) 32.f7+:

A) 32... Kxf7 33.Rh7+ Kf(g)8 34.Rxd7 Rxe4+ 35.Bxe4 Re8 36.Kd3 + - [2B vs n].

B) 32... Kf8 33.fxe8=Q+ Rxe8 34.Rh8+ Kf7 35.Qxe8+ Qxe8 36.Rxe8 Kxe8 37.Bxg6+ + - [2B+P vs n].

C) 32... Qxf7 33.Rh8#.

Mar-31-21  Brenin: My first reaction was that 31 Qxg3+ must be the key move, before realising that the Q is pinned. No matter, the R can open up Black's defences instead and allow f7+, while the pinned Q can deny the Black K access to the e-file. There's no mate, but the undefended Q on d7 means that White comes out a piece ahead.
Mar-31-21  malt: The White Queen is pinned, desperate times, need desperate measures.

31.R:g6+ fg6

32.f7+ K:f7

(32...Q:f7 33.Rh8+ )

33.Rh7+ Kf8 34.R:d7 R:e4+ 35.B:e4

Mar-31-21  Cellist: I saw the nice combination. It is good to keep in mind that White already was a piece ahead at the start. The combination allows a safe trading down while maintaining the advantage and gaining an even stronger position.
Mar-31-21  Brenin: Eliskases had an interesting chess career: he was champion of three different countries, and represented three countries (not the same three) at the Olympiads. And how many other players could claim victories over Capablanca and Fischer?
Mar-31-21  Rama: I tried 31. Qe7. After the exchanges, move the K out of check and there it is -- the diagonal, the rooks, no escape.
Mar-31-21  Brenin: <Rama>: After 31 Qe7, Black wins with 31 ... Nxe7 32 fxe7 Rxe7+ and 33 Rxc3.

Mar-31-21  1g1yy: The game line was actually my very first guess at this but I wasn't convinced, nor even mildly sure it was right. Being sorta new to getting back into chess, my 2 ply mind won't allow me to see the position of the vacated squares clearly enough to think out the position. So, not many moves in, I'm lost. I was figuring Kxf7 to satisfy the f7+ move, but I couldn't find a clear win and it was too far down the line for me to even see that Qxf7 results in #1. Even when I used the board to look at the continuation it took a while before I saw "Oh yea! that whole bishop file is now open to H8 which is a covered square for Rh8#!" Lol.

I need more practice at lines in my head. Often in games I get burned not seeing newly occupied or newly vacated squares... even just a few moves out. Gotta start somewhere I guess.

Mar-31-21  TheaN: <31.Rxg6+ fxg6 (Kf8 32.Rh8#) 32.f7+ Kxf7> of note here, White can simplify after Kf8 or return to the main line with Rh8+ <33.Rh7+ Kf8 34.Rxd7 Rxe4 35.Bxe4 +->

The reason why this jumps out is the defensive reason of the combination: the White queen's pinned and this is pretty much the only way out of it.

Mar-31-21  Pedro Fernandez: Hi <Chris>, time without to speak with ya. Here the nice move is 32.f7+!. Cheers!

31...fxg6 32.f7+ Kxf7 33.Rh7+ Kg8 34.Rxd7 +-
Mar-31-21  AlicesKnight: I found the game line, leading to 'exchange' of Qs and Rs, and a winning advantage for White. I like the charge of the f-pawn.
Mar-31-21  saturn2: Black threatens an exchange Q for R but white can force Q for R plus wimning back a pawn.

WHITE TO MOVE

This diagram shows a critical moment of the game, where Portisch was lucky. He could have been outplayed had his opponent found the correct moves. White should have played the simple move 17.O-O with a slight advantage (computer evaluation by SF14: +0.83).

Instead he played the risky (and dubious) 17.Be3?!, and after the obvious reply 17...d4 Portisch blundered with 18.Bxd4?? (18.Bd2 was in order), and after 18...Bxf3 Black is lost (computer evaluation by SF14: -5.00). Portisch played 19.Qe3 (a move that he probably had anticipated when he played 17.Be3). See diagram below:

BLACK TO MOVE
In this position Eliskases played 19...Qe6??, overlookling that he could have obtained a winning position after the queen's check on a5. A likely continuation would have been the following one: 19...Qa5+! (??+) 20.Bc3 b4! 21.Bd4 Bd5, and Portisch could have resigned, as he loses a whole piece while keeping an inferior position. (See diagram below):

Jul-25-21  Gaito: "Always give a check, it could be mate".
By missing the winning check 19...Qa5+! (–+), Erich Eliskases missed an opportunity to add grandmaster Lajos Portisch to the list of his illustrious victims (Keres, Flohr, Capablanca, Fischer, etc.)

  Retireborn: Sorry <Gaito>, but glancing at your diagrams it is evident that you've moved the a3 pawn back to a2. With the pawn on a3, 19...Qa5+ loses to 20.b4.

The good news is that Eliskases does have a win against Portisch (Costa del Sol, 1961)
