Kibitzer's Corner
Aug-07-07  Maynard5: This is a rather bizarre game. Black tries to create a kind of Benko gambit position out of a King's Indian, but White's resulting passed pawns on the queenside become a long-term threat. There is an interesting endgame fight in which Black tries to break through in the center, while White advances his queenside majority. Eventually, the queenside pawns are lost, but White is then left with several passed pawns on the kingside, and is eventually able to force the f-pawn through to the seventh rank.
Aug-07-07  Tomlinsky: It looks like Guseinov had ambitions of some type of risk-free Dynamic Attack setup or something. Instead he ended up with passivity bordering on being comatose if that was the intention. Too much 'preparation' instead of gambiting the pawn for queen side activity and following through if that was the overall plan coming out of the opening.

  An Englishman: Good Evening: Resignation because 56.Nd7 and 57.f8/Q will follow. The entire game has much of interest; pity Black's creativity went unrewarded.

  agb2002: White has a bishop for a knight.

Black threatens c2.

The black knights can't reach f8 at once but the white knight can. These details suggest 53.Bxh7+:

A) 53... Kxh7 54.g6+

A.1) 54... Kg8 55.f7+ Kg7 (55... Kf8 56.Nd7+ Ke7 57.f8=Q+ Kxd7 58.Qxb4 c2 59.Qa4+ wins) 56.Nd7

A.1.a) 56... c2 57.f8=Q+ Kxg6 58.Qg8+ Kh6 59.g5+ Kh5 60.Nf6#.

A.1.b) 56... Kxg6 57.f8=Q Nd5 58.Ne5+ Kh7 (58... Kg5 59.Qg7#) 59.Qf7+ and mate next.

A.2) 54... Kh6(8) 55.f7 Kg7 56.Nd7 transposes to A.1.

B) 53... Kf8 54.g6

B.1) 54... c2 55.g7+ Ke8 56.g8=Q(R)#.

B.2) 54... Ke8 55.g7 Kd8 56.g8=Q+ Kc7 57.Qc4+ wins.

C) 53... Kh8 54.g6 Nd6(8) 55.Nf7+ Nxf7 56.gxf7 and mate in two (56... Kxh7 57.f8=Q Kg6 58.Qg7#).

Yes, Brilliant!

I saw that instantly, surprised that van Wely missed it. If this was a blitz game, that would explain it. But it wasn't. I know from experience that once you see a win, you often don't look for a quicker or prettier win. So that's probably what happened here. Either that or time pressure.

Jun-03-20  saturn2: Bxh7 followed by g6+. Now the pawn g6 supports f7 and Nd7 supports f8Q. Black is too slow on the queenside.
Jun-03-20  Cheapo by the Dozen: Ya know -- while it's obvious that White can queen before Black does, it's not nearly as clear that White could then stop Black from queening as well. Good thing that there'a a mating net to obviate the problem.
Jun-03-20  Brenin: With Black threatening c2, 53 Bxh7+ is the only realistic candidate move, and it's just a question of showing that none of Black's responses saves him. Black was doing fine, with his central pawns looking more threatening than White's Q- and K-side majorities, until he lost the plot with 33 ... Ra8 and 34 ... g5. Centralising the N on c7 with 49 ... Nd5, rather than marginalising it on a6, would have kept him in the game.
Jun-03-20  malt: Have 53.B:h7+ K:h7 54.g6+ Kg8 55.f7+ Kg7 56.Nd7 K:g6 57.f8/Q

57...c2 58.Qg8+ Kh6 59.Ne5 wins
57...Kh7 58.Nf6+ Kg6 59.Nh5 wins
57...Kg5 58.Qf6#

Jun-03-20  TheaN: I think <agb> covered this Wednesday variations wise, so I'll go over it deductive.

In the puzzle's starting position it's obvious Bb1 will be questioned by a rather quick c2 and after Bxc2 and an eventual Nxd3 the game's drawn so White will have to act fast. Now, rather.

If the bishop is dropping, we may as well throw it in the fray with a bang. <53.Bxh7+>. If this doesn't work, nothing does. Pawns are the soul of the game, both offensively and defensively. With this move White tackles both aspects; he takes out Ph7 as defender and clears the way for Pf6 and Pg5 as offenders.

Declining gives rise to some rather interesting lines, but in all it's obvious Black lost a pawn, tempo and the bishop plays crucial part in getting the pawns across. 53....Kf8 seems to bring the king out in the open but the knight and f6 pawn cover the escape: after 54.g6 Black can only prevent g8Q# with 54....Ke8 55.g7 Kd8 56.g8Q+ Kc6, but after 57.Qc4+ #6 this idea obviously fails. 53....Kh8 seems the 'better' decline (it isn't) but cornering the king only works if there's no tabs on the adjacent squares. After again 54.g6, Black's dealing with the immediate Nf7#. Only 54....Nd6/Nd8 prevent this, but Black's getting mated anyway after 55.Nf7+! Nxf7 56.gxf7 blocking off the king 56....Kxh7 57.f8Q Kg6 58.Qg7#.

So, <53....Kxh7>. Frustratingly for Black, this gives away another tempo that White desperately needs. <54.g6+>. To the back rank will force promotion: 54....Kh8 forces 55.f7 Kg7, after 54....Kg8 55.f7+ he also has the option to go to f8. 55....Kg7 seems to slip through the cracks but 56.Nd7 #5 forces promotion without compensation and Black gets mated with QNP. 55....Kf8 does definitely allow an escape and is probably Black's <best>. Still after 56.Nd7+ Ke7 57.f8Q+ Kxd7 58.Qxb4 #15 I understand Guseinov didn't want to go here; for what it's worth 58.g7 #12 is apparently faster to mate, but this is a typical computer line where we just allow Black to queen. Qxb4 is the human line.

Then last but not least. Can we prevent White from gaining a tempo on the back rank? No not really though after <54....Kh6?> it seems like it. This is Black's <worst>, but I can understand that in a defending situation, one might miss <55.Kh4! #1> as <56.g5#> cannot be prevented.

Pretty grim characterization of Black’s play. He seems better after 24 moves, so the opening looks fine to me, or at least Van Wely didn’t figure it out OTB.

In fact, it was VW’s clinging to the Q-side pawns that allowed G to win material in the center.

44 … c3 was a losing move. Black should have played 44 … Nxe4+. White returned about half of his advantage with the next move, 45 Bb1. Instead, 45 Bc2 would have protected the a-pawn.

Black clawed his way back into the game reaching this position.

Instead of continuing to attack the b-pawn with 49 … Nd5, Black played a second losing move, 49 … N7a6. It's hard to understand foregoing the b-pawn after seeing how to win it! To be clear, White can save the b-pawn with 49 … Nd5 40 Nf3, but that allows Black to push his d-pawn.

In the end, White deflected Black's defender with that same b-pawn (52 b7) to set up the winning bishop sac.

  chrisowen: Flushed h7 Welywolves of London?
Jun-03-20  Damenlaeuferbauer: After long pondering, the very strong Dutch chess player Loek van Wely finally found the win with the bishop sacrifice 53.Bxh7+!,Kxh7 (53.-,Kf8 54.g6 +-; 53.-,Kh8 54.g6,Nd6/Nd8 55.Nf7+!,Nxf7 56.gxf7,Kxh7 57.f8Q +-) 54,g6+,Kg8/Kh8/Kh6 55.f7(+),Kf8/Kg8 56.Nd7(+) +-. It is because of games like this, why they call him in Holland "King Loek"!

  Fusilli: <Damenlaeuferbauer: After long pondering, the very strong Dutch chess player Loek van Wely finally found the win...>

Poetic but rather off. This is a win a GM "finds" in a few seconds, not after long pondering. And he didn't find it. He created it. His previous move (52.b7) gives away a passed pawn to remove the knight that is controlling the d7 square, making Van Wely's intentions quite clear.

  chrisowen: War z hash no?
Jun-03-20  Brenin: <Fusilli> is perhaps unused to reading <Damenlaeuferbauer>'s responses to POTD. They almost invariably start with some long pondering, followed by a graceful compliment to the player concerned. It's rather like Novak Djokovic bouncing the ball ten times before serving, or a triple jumper clapping his hands above his head before his run-up. I view it as a rather charming digital throat-clearing, which I would miss it if it disappeared.
Jun-03-20  saturn2: <Predrag3141White returned about half of his advantage with the next move, 45 Bb1. Instead, 45 Bc2>

Maybe white saw 45 Bc2 d3.

Far from obvious to me after 46.. Nxa4.
But at least I know someone reads my posts.
