| Feb-16-08 | | hedgeh0g: No kibitzing yet? This game was amazing! |
|
| Feb-17-08 | | notyetagm: Go Chucky!
|
|
| Feb-17-08 | | mindkontrolle: WOW! beautiful Queen dance from Ivanchuk... |
|
| Feb-17-08 | | Nezhmetdinov: this looks like the stem game: Smejkal vs I Zaitsev, 1970
Chucky's conception of getting two rooks for the queen is based on an acute appreciation of black's pawn weaknesses, his king's insecurity and the difficulty for black of generating any counterplay whatsoever - will anyone play into this line again? Is this just a cute "one-shot" novelty? Whatever, I love Ivanchuk and if he can win more than one bloody game here (as in Corus) maybe he will win Linares again? Here's hoping! |
|
| Feb-17-08 | | Jarlaxle: ivanchuks play is incredible here. Watching some of his games blows me away, like watching some classic Tal games. |
|
| Feb-17-08 | | notyetagm: <Jarlaxle: ivanchuks play is incredible here. Watching some of his games blows me away, like watching some classic Tal games.> Ivanchuk is a genius, he is just not consistent and he takes losses badly. Anyone else notice that Ivanchuk is so far undefeated this year? His record: +1 =12 -0 at Corus, +1 =1 -0 so far here at Linares. |
|
| Feb-17-08 | | SniperOnG7: <Nezhmetdinov> Nice observations. Yes, Black has the more exposed King, and since White is able to open the files, his Rooks are at least as equal in strength as a Queen. In addition, since White's Queenside pawn structure is compact, un-marched and slanting inwards (ie b2, c3 instead of say b3, c2), it is virtually impossible for Black's marvellously looking Bishops to do any actual damage. Meanwhile, Black's Queenside pawns are in a totally opposite situation, being overextended. This dual weaknesses of the King and pawns leave the Bishops in a very defensive role even though Black has heaps of space to manoeuvre (this shows the unadvertized side of the "space advantage" in which everything in the camp becomes exposed and loose). A quick glance may lead to the conclusion that the board seems wide open. However, the key here that makes it not so is Black's e4 pawn. Being nicely blocaded, the pawn in turn blocks Black from any headway into White's Kingside. I find it interesting that if Black's Pe4 disappears into White's pocket, White will actually be losing! An amazing game by Ivanchuck, being able to see such insight during the game and distilling a complex opening stage into a seemingly simple and effortless middlegame/endgame where the differences between White and Black contrasts nicely even for a patzer like me to see (and "annotate"). Bravo to Ivanchuck for first "freely" presenting Leko with the Bishop pair, space and the Queen...then asks Leko to surrender the 1-0 scorecard. |
|
| Feb-17-08 | | notyetagm: From the Morelia-Linares (2008) forum: <stonebrain2006: Impressive game by Ivanchuk. Ironically, in this age of exhaustive computer analysis, Leko didn't know (or forgot)that 8.d4 should have been answered with 8....d6 Actually he played 8....Nxd4 allowing the sac 9.Bxf7+!! with advantage for White.> According to Opening Explorer, White scores only <50.4%> against 8 ... d7-d6 while scoring <60%> against 8 ... ♘c6xd4. Opening Explorer also shows that when White responds to 8 ... ♘c6xd4 with 9 ♗b3xf7+!, he scores a whopping <66.7%> (+5 =6 -1 in the 12 games in the database). <All this was known since a game David Bronstein vs Potucek played in ... 1946!!!> This database does not contain the Bronstein game referenced above; it contains only the 12 games found at http://www.chessgames.com/perl/ches.... |
|
| Feb-17-08 | | Gilmoy: Leko: <But -- you cannot move your Queen so many times in the opening --> Ivanchuk: <Go Speed Racer, go Speed Racer, go Speed Racer, go!> |
|
| Feb-17-08 | | Atking: <Leko spent too much time in several moves that seemed natural; for example he spent almost thirty minutes playing 18..Ra8 and soon fell in time trouble.> According to <Bxg7> On the Tournament page (here almost a copy) with my little chess pocket (Must be checked with a computer)I gave 18...Bd6 with for example: 19.h3 e3 20.Bxe3 Bh2+ 21.Kh1 Bxg2+ 22.KxBg2 QxQa7 23.KxBh2 Qc7+ white seems better here but the black Q is unusually strong and may give a perpetual. Leko must have a think about it... To say a) 24.f4 Rxf4 25.BxRf4 QxBf4+ 26.Kg2 Qg5+ 27.Kf2 (Kh1 Qd5+ Kh2 Qd6 and so on) Qf5+ 28.Ke2 Qxc2+ is incredibly complicated or b) 24.Kg2 Qc6+ 25.Kf1 Qf3 26.Nd2 Qxh3+ 27.Ke2 Qg4+ 26.f3 Qg2+ Bf2 28.Re8+ Ne4 29.Rf8 looks pretty drawish... both with some interesting chances for Black ( passed pawns for a piece). Indeed I understand that Leko could be afraid to play under his opponent's preparation (As Ra8 is the most natural one) and though a lot on that move. Finally Ivanchuck got a small edge, the kind of advantage that Leko uses himself very well. |
|
| Feb-17-08 | | notyetagm: <Gilmoy: Leko: <But -- you cannot move your Queen so many times in the opening -->> Ivanchuk: Well, what are you going to do about it?
Leko: Nothing.
A weakness is not a weakness unless it can be exploited. :-)
|
|
| Feb-17-08 | | Atking: Just realising that I gave to <Bxg7> for the brave a <21...Bxg2> |
|
| Feb-17-08 | | Avarus: As <notyetagm> points out, the opening is well known. In fact I was under the impression this is an opening trap, because 8..Nxd4 looks good but is very bad like in the game. |
|
| Feb-17-08 | | percyblakeney: Nice to see such a convincing win for Ivanchuk, he seems unusually stable so far this year (it has been easier to beat Anand and Kramnik). |
|
| Feb-17-08 | | malvar: <hedgeh0g> This game was amazing indeed. It certainly must be further studied to know how much of it was blunder chess and how much was genius; but with these 2 titans of the board, I doubt it was much blunder chess ( perhaps their thoughts are too advanced for my brain to comprehend) WHY DIDN'T LEKO CAPTURE 29...Bxb3???? I know there are the dangers of moving the rooks to the 8th rank but I feel black can still defend. Can anyone shed some light on this? |
|
| Feb-17-08 | | Atking: This one is not as difficult as you think <malvar>. As you noted 30.Rd8 recovers the piece. Then without Bf8 White could force c4 (For example by Rc8) to take d4 square. Finally light square bishop can't nothing against Bd4 and Ra7. One point of h4 amongt others is to stop the threat of a B or Q on h3 (Bf3&Qh3 or Qf3&Bh3). Whatever no really time for that. |
|
| Feb-17-08 | | Ipecac: <malvar: WHY DIDN'T LEKO CAPTURE 29...Bxb3????> 30.Rd8 Kg8 31.Raa8 (losing the Bishop with even worse endgame for Black) At least at first glance I think so.
|
|
| Feb-17-08 | | malvar: Ok, so, I asked for a little help from Fritz 6 and it came up with Bxe3 as its first option: Depth=17/38 793 kN/s
1. =(0.06): 29...Bxb3 30.Rd8 Qf5 31.Raa8 Kg8 32.Rxf8 Qxf8 33.Rxf8 Kxf8 34.Bxc5+ ...Which may or may not be a draw depending on the end game prowess of the masters(not on mine) but, I would have at least tried offering a draw after that. Different colored bishop ending... half a point sounds fair considering the underestimation of the opening. Better than the 1-0 Thanks for replying.
Maybe someone with a better engine has a better analysis. |

| Feb-17-08 | | Marmot PFL: <virginmind> I thought 38...Bh3 was fine for black and an easy move to see, but Leko was in severe time pressure. |
|
| Feb-17-08 | | Atking: When you ask for a better engine you could be sure that virginmind comes to help. Reading <malvar> question I though myself there is no urgency to take c5. After 32.Rab8 Bc4 I suspected 33.b4! cxb 34.cxb ~35.Bc5. but I never suspected that Black could gambit the 2 pawns!? In F11 line is 36.Kg2 really the best? hxg hxg and Kf1 isn't better. Imagine White K in e3 Black K in e5 then Be7 g4; Bf8~Bg7+ Kd5 (Else White plays Kd4) Kf4 Bd1; b3 Bxb3; Kxg4 Opposite color B ending are not always easy to draw. |
|
| Feb-17-08 | | malvar: Thank you virginmind for the surprising insight into the situation and the further analysis. I'm stunned at the continuation line provided by Fritz 11. I can clearly see a difference in between the engine generations. |

| Feb-17-08 | | herby rawley: wow ..just sort of reperusing chess morphy to botwinnik by konig 1950
ch. 1 deals with early attempts at a direct and early d4in the Lopez not exactly the same ..but sort of a return to 'yesteryear' interesting
entertaining,ambitious,what chess at this level should be..bravo |

Some amazing decisions from Ivanchuk, the best being the decision not to immediately take the c5 pawn on move 29. He decided to keep the tension knowing he had better chances than Leko. A fantastic effort from Ivanchuk who showed some quality chess insight. Chucky at is very best. |
