|Jun-10-18|| ||RKnight: I think White would have improved over the game line with 30 gxh7+ Kxh7, 31 Qc2+ and the white position is more defensible.|
|Jun-10-18|| ||al wazir: <RKnight: 30. gxh7+> Kh8, and now black threatens 31... Rxa3+.|
|Jun-10-18|| ||jith1207: <RKnight>: I think black would play 30..Kh8 31.Qc2 Rxa3+ 32.Qa2 Rxa2+ 33.Kxa2 Qa6+ 34.Ba5 Qxa5#|
|Jun-10-18|| ||jith1207: <al wazir> I think Rb3 would present similar challenge after Qc2 in your line. Haven't checked engine but think that would be hard to meet with the bishop after that either at b2 or b4.|
|Jun-10-18|| ||pdxjjb: Gelfand's mistake was actually 24. g5. Instead, 24. Rc1 was necessary to indirectly guard the e5 bishop against ... Nc6. (With the rook on c1, Nxe5 is met by Rxc8, ... Qxc8; Qxb5 winning the exchange.) Of course Gelfand does play 25. Rc1, but by then black has gotten the N over to c6 which makes the pawn push to d4 devastating.|
|Jun-10-18|| ||Mayankk: Clearing the long diagonal so that the c1 Rook canít move once Black piles further pressure on b2, as it is tied to the defence of other Rook... Amazing foresight. And of course beyond me.|
|Jun-10-18|| ||Walter Glattke: 33.Qb4 Nc2+ 34.Rxc2 Qxh1+ 35.Ka2 Rxb4|
|Jun-10-18|| ||mel gibson: That's difficult as it's the only winning move.
I tried many others & they all fail using a computer.|
|Jun-10-18|| ||morfishine: Great game by Big AL! I don't see much insanity, just powerful responses to White's slight inaccuracies|
|Jun-10-18|| ||agb2002: Black has a knight for a bishop.
The obvious 25... Nxe5 loses to 26.Rxc8+ Qxc8 27.Qxb5.
Black can concentrate forces on b2 and open the a8-h1 diagonal, exposing the rook on h1. This suggests 25... d4:
A) 26.Bxd4 Rb8
A.1) 27.Rc2 Nxd4, with the quadruple threat Qxh1+, Nxc2, Rxb2+ and Nc6, wins.
A.2) 27.Bc3 Rxb2+ 28.Ka1 (28.Bxb2 Qxb2#) 28... Rb3 and the threat Rxc3-Qb2# seems to leave White defenseless.
A.3) 27.Qc2 Nxd4 28.exd4 Rxb2+ wins.
A.4) 27.b4 Nxb4 looks winning.
B) 26.Rxc6 Qxc6, with the double threat Qxh1+ and Rxe5, wins decisive material.
C) 26.exd4 Rxb2+ 27.Ka1 Rxf2 wins a pawn.
|Jun-10-18|| ||agb2002: I overlooked 29.Bb4 in my line A.2 with the double tyhreat Qxb3 and Qxc6, when White emerges with the advantage.|
|Jun-10-18|| ||wtpy: I got most of this. Certainly didn't consider grasping the nettle with 26 ed4 as white's best defense as stockfish suggests.|

|Jun-10-18|| ||Jimfromprovidence: The line after 29 Qc2 Ra6 (threatening 30 Rxa3+) 30 Qa2 looks pretty complicated to me.|

White to play and win.
|Jun-10-18|| ||pdxjjb: <Jimfromprovidence> I agree, that's probably white's best chance. Black has to find ... Qe7 and then some other moves that really aren't obvious, at least not to me, although they're obviously obvious to an engine. ;-) If black goes astray in there, white can equalize.|
|Jun-10-18|| ||saturn2: I thought of 25..Ra5 threatening Rxa3|
|Jun-10-18|| ||morfishine: But <jimfromprovidence> its Black's move|
|Jun-10-18|| ||Patriot: Black's rook on b5 is loosely defended which is why <25...Nxe5 26.Rxc8+ Qxc8 27.Qxb5> is bad for black. Black's advantage though is pressure on b2 and the loose bishop on e5 (given the right conditions to capture it). The white queen also seems to be in a precarious position although I see no way to immediately take advantage of it. After looking at <25...Rb8> and concluding that doesn't work, I decided on <25...d4> seeing that <26.Bxd4 Rb8> puts a lot of pressure on b2. After that I had no idea how the rest would be played out.|
|Jun-10-18|| ||Jimfromprovidence: <pdxjib> <I agree, that's probably white's best chance. Black has to find ... Qe7 and then some other moves that really aren't obvious, at least not to me, although they're obviously obvious to an engine>.|
I couldn't find anything as well, so I ran the position through the CG Stockfish program for 6 minutes. Here is the output.
-2.61 (30 ply) 30...Qe7 31.a4 Rab6 32.Rb1 Qc5 33.Rbc1 Rb3 34.Bb2 Qd5 35.Rhd1 Nb4 36.Rxd5 Nxa2 37.Rd8+ Rxd8 38.Kxa2 Rb4 39.Ka3 Rh4 40.Bd4 Rxh5 41.f4 a6 42.Rc6 Ra8 43.Kb4 a5+ 44.Kb3 Rh2 45.Rc5 h5 46.gxh6 gxh6 47.Rb5 h5 48.Rg5+ Kh7 49.Rg7+ Kh6 50.Rxf7 h4 51.Kc3
To make a long story short, black is able to grind away an exchange plus pawn advantage after 40...Rxh5, below.

Sorry that I messed up my original post. It should be <Black> to play and win.
|Jun-10-18|| ||Cheapo by the Dozen: I actually saw ... d4, and its benefit of opening the long diagonal for a discovered attack on the h1 rook. Unfortunately, I spaced out on the easy point that once the bishop moved ... Rb8 became viable.|
|Jun-11-18|| ||Howard: For the record, Gelfand had a more-than-impressive rating of 2700 going into the Linares tournament. In fact, he was only the fifth player at the time to ever achieve a rating of at least 2700...|
..but nowadays, a 2700 rating is about a dime-a-dozen.
|Jun-11-18|| ||patzer2: White's decisive error according to the computer was 24. g5?, allowing 24...Nc6 -+ (-1.76 @ 35 ply, Stockfish 9 analysis of move 25.?).|
Instead, 24. Rc1 = (0.00 @ 47 ply, Stockfish 9 analysis of move 25.?) gives White even chances.
Earlier, 23. Ka2 ⩲ (+0.45 @ 36 ply, Stockfish 9 analysis of move 23.?) improves over 23. Be5?! Qb7 ⩱ (-0.40 @ 41 ply, Stockfish 9 analysis of move 23...?).
|Jun-11-18|| ||Olavi: Beliavsky in New in Chess 3/1991:
The only way to prevent Ra6 was 29.Qc2, although 29...Qa6 30.Ka2 Rb4!? 31.g6 hxg6 32.hxg6 T8b5 33.Rh8 Kxh8 34.gxf7 Qxa3 proves that the white position is difficult.
Perhaps he analyzed more rigorously in the Informator? Here he concentrated on the earlier, theoretically interesting part.
|Jun-12-18|| ||Howard: Considering that Stockfish believes that Black's strongest move on move 12 was 12...dxc4, it's rather surprising that the Informant gives Beliavsky's 12..b5 two exclamation marks---not to mention giving it first place (by a hefty margin) in the TN section.|
