Grischuk and Ivanchuk reach Semi-Finals after World Cup Playoff

Post by ciccio on Sun Sep 11, 2011 7:54 pm

The World Cup Quarter Finals were completed by two rapid matches on Sunday. Alexander Grischuk exploited an early error by David Navara as white to win the first game of their playoffs and eventually drew the second. Vassily Ivanchuk held a lengthy ending against Teimour Radjabov in game one as black before torturing him with a small advantage until he won in 54 moves in the second. The semi-final pairings are Peter Svidler vs Ruslan Ponomariov and Vassily Ivanchuk against Alexander Grischuk, Oddly if you replace Grischuk with Anand these are the same pairings as the 2001-2 FIDE World Championships held using the same format. Not much has changed in a decade! The players stay until the end now as there are three Candidates places available so a 3rd-4th playoff is required. I'm assuming this playoff is the same format as the final.

Ivanchuk 1.5-0.5 Radjabov

Vassily Ivanchuk went through 2.5-1.5 against Teimour Radjabov requiring just the rapid games to do so.

Game 1: Rajdabov-Ivanchuk was a complex Symmetrical English with chances for both sides for a long time. Ivanchuk gave up the exchange and eventually this turned out to be favourable to Radjabov. On move 39 (see below) Ivanchuk had 6 minutes 14 seconds and Rajdabov 2 minutes. Radjabov invested most of his remaining time on 40.d6 leaving him with 31 seconds and the increment of 10 seconds to play the remaining moves and this aided Ivanchuk's defence immensely. The R+P vs R+B ending seems to be totally drawn and were handled well for Ivanchuk on the defending side. Radjabov gave up trying to win R vs B on move 120.
Game 2: A Fianchetto Gruenfeld where Ivanchuk played for the exploitation of the minimal advantage of doubled b-pawns and an offside knight on the queen-side. Ivanchuk played this nicely consistantly causing Radjabov problems until pressure and time trouble caused his position to collapse. On the whole it was a great lesson by Ivanchuk on how to play a position where your opponent is reduced to passivity and there is play on both sides of the board.

Of course white doesn't swap rooks. He has plans for it down the h-file.

41...Na4

[41...Ra8 insisting on the exchange would either activate the rook or get the exchange, both times relieving the defence.]

White now breaks through whatever but black's next accelerates things.

52...Nb6 53.hxg6! fxg6

The worst of the three recaptures but nothing is to be done anyhow.

54.Bxb6 1-0

Grischuk 1.5-0.5
Alexander Grischuk after surviving a lost position the previous day (he admitted at the press conference that he started thinking about what he had to do to go home, including changing his flight ticket) went through against David Navara in the rapid playoffs 1.5-0.5.

Game 1: Navara-Grischuk. Navara seems at all costs to avoid time trouble and so plays these rapids at almost blitz pace. This has proved very successful in previous rounds as it puts a lot of pressure on his opponents. But today he didn't spend enough time and made a very bad blunder just out of the opening as white in a Caro-Kann and he could either take a very bad ending a pawn down or do what he did which was go for complications which ended very quickly with a position without any defensive possibilities. Grischuk took his time but made no mistake in converting.

Effectively costing Navara the match.

15...d4! 16.Qa4+

[16.0-0 dxc3 17.Bxf5 exf5 18.bxc3 0-0 accepting the lost pawn was another way to try and defend.]

16...b5 17.Qxa6 Rxe5+ 18.Kf1 0-0 19.Bxb5 dxc3 20.bxc3 Qd2

Navara is completely busted. Quite rightly Grischuk took his time but it is all over for this game.

21.Be2 Qxc3 22.Re1 Rd8 23.h4 Ng3+ 24.fxg3 Rf5+ 25.Kg1 Qxe1+ 26.Kh2 Qa5 27.Qc4 Qc5 28.Qb3 Rf2 29.Bf3 Qc2 30.Qb6 Rf8 31.Be4 Qxa2 32.Rd1 Rd2 33.Rf1 Qb2 34.Qc5 Rdd8 35.Qe7 Qd4 36.Bb1 Qd6 37.Qb7 Rb8 38.Qe4 f5 39.Qe3 Rb4 40.Kh3 Kh8 41.Ba2 Re4 42.Qf3 Qe5 43.Qa3 Rb8 0-1

Game 2. Grischuk-Navara. There isn't much to be done when you're black in a must win situation as you need the co-operation of your opponent. Navara chose to play proper chess and hope something turned up. Grischuk was critical of his own play in the game as he ended up a pawn down in a Queen Knight and Pawns ending but the defence was not too hard for him eventually.
