Corus Chess Tournament:Group A:Round 7 results

Round 7 of the Corus Chess Tournament, resulted in another loss for GM Ivanchuk <:(. Having the white pieces against GM Movsesian, did not help the Ukrainian GM as Ivanchuk lost the game in 35 moves.

Ivanchuk played a rare continuation on move 9 against Movsesian's Sicilian Defense:Scheveningen variation,

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. Be3 Nc6 7. f4 Bd7 8. Be2
Be7 9. Ndb5

The game continued 9.... Qb8 10. a4 O-O 11. O-O Rd8 12. Kh1 Nb4 13. Bf3 e5 14. Qe2 Bc6

Now Ivanchuk was able to exchange pawns to gain a half-open f-file, useful in attacking Movsesian's king:

15.fxe5 dxe5

Ivanchuk was able to play 16. a5, which made it very difficult for Movsesian to gain typical queenside counterplay against Ivanchuk's position (using the moves ....a6 and ...b5).
Note that the chess program Deep Rybka 3 preferred to play 16.Rad1 which after 16...Rxd1 17.Rxd1 would have gained Ivanchuk control of the open d-file with his rook. Then play might ha ve continued: 17...a6 18.Na3 Qc8 19.Nc4 Qe6 20.Bb6 Rc8 yielding Ivanchuk a definite advantage).

Movesian continued the game by playing 16...a6 (creating a pawn lever with Ivanchuk's a-pawn.).This lead to an exchange of pawns on b6, and then an exchange of a pair of rooks on a8.
Ivanchuk then created a double-attack against Movsesian's pawn on b6 by playing 19.Na4. The game continued:

19...Bc6 (creating an attack against Ivanchuk's knight on b5, tieing down Ivanchuk's queen to defend the knight). The game then continued 20.c4 Nxe4 21.Nxb6 f5. which gave Movesian a beautifully placed knight on e4. Ivanchuk believed this perspective of mine because he immediately decided to remove Movesian's knight on e4 by playing 24.Bxe4 and after 24...Bxe4,
Ivanchuk was forced to spend a tempo to protect his double-attacked c-pawn, with the move 25.b4. However, Ivanchuk had two connected passed pawns to Movesian's one and Ivanchuk's passed pawn duo would have a much easier time making their way up the board towards queendom, than Movesian's.

A key moment in the game occurred on move 26 for both players. Ivanchuk, pressing hard for a win, in a position which probably was the reason he decided to play 26.Rb1?! which Deep Rybka 3 evaluated as being "dubious" at best.( Instead he could have played 26.Nxe4 and after 26...Qxe4 27.Qf3 Nb4 28.Qxe4 fxe4 29.Ng4 Kg8 30.Nxe5 Rd5 31.c6 Bd6 32.Nc4 Nxc6 33.Nxd6 Rxd6 with a draw the likely result).

After 26...f4 Ivanchuk's dark-squared bishop was forced to retreat to g1., ie 27.Bg1 ,Movesian then also moved his bishop, 27...Bg6 to allow his passed pawn to march up the board.

Another key moment of the game now occurred. Ivanchuk decided to play 28.Nc4?! with the idea of 29.Na5 (which would use his rook on b1 and the rook on a4 to advance his b-pawn to b5).
However, this was dubious because of 28...e4 -/+ (Instead according to Deep Rybka 3, Ivanchuk should have played 28.Rd1 however even 28...e4 29.b5 f3!? 30.Qa2 Bh5 31.c6 Qb8 32.Rf1 Qe5 33.Ncd5 Nb4 34.Nxb4 Qxb5!? 35.Rf2 Qxb6 36.Nd5 Qxc6 37.Nxe7 Qd7 Movesian would be a pawn up.)

The game continued with Movesian playing 28...e4 which really anchored his knight on d3, and then after another mistake by Ivanchuk 30.Na5?, his position looked extremely bleak. (Better was 30.b5!? with a possible continuation being: 30...Bxc5 31.Bxc5 Nxc5 32.Ne5 Nd3 33.Nxg6 hxg6 -/+ and according to Deep Rybka Ivanchuk would still be in the game.)

Movesian then played 30...Qa8 and Ivanchuk tried to get one of his b-c passed pawn duo nearer the queening square when he played the pawn sacrifice 30.c6 (Deep Rybka 3 gave the move 30. Qf1 a better evaluation after which play might have continued 30...f3 31.Be3 Nxb4!? 32.Nc4 Nc2 33.Bf4 Bxc5 -+).

After 30...Bxb4 (forking both of Ivanchuk's knights),Ivanchuk was in all kinds of trouble. He decided to continue by playing 31.Nb7 (attacking Movesian's rook). However, Movesian simply ignored this attack and played 31...f3 attacking Ivanchuk's queen, winning a tempo the game continued 32.gxf3 (Better but still losing was 32.Qf1 Rf8 33.Bd4 fxg2+ 34.Qxg2 e3 35.Bxe3 Qe7 36.c7 Bxc3 37.Nd6 Qxe3 38.Rf1 Bf6 39.h4 Qe6 40.Qg3 Qd5+ 41.Kh2 Qc5 42.Rf3 Qxc7 and with the loss of his passed c-pawn Ivanchuk would be resigning.)

Returning to the game, which continued 32...exf3 33.Qxf3 Rf8 34.Qd5 Bxc3 (going up a bishop), 35.c7 Nf4. Ivanchuk now resigned because after he played a move such as 36.Qf3 Movesian would be up a rook and bishop after 36...Bxb1.

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed

Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia

A person's true wealth is the good he or she does in the world. - Mohammed

Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein

The best way to find yourself, is to lose yourself in the service of others. - Ghandi

The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller

Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns

Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama

Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -

Milan Kundera, The Unbearable Lightness of Being

The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
