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.

A great game. Extremely complex and exciting with a dynamic unbalanced position.

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.

Feb-17-08  percyblakeney: <38.Re1< Keeping the rook on the 'd' file and defending it from the 38...Qf3 attack by 38 Ne2 is better.>>

Yep, this looks like Ivanchuk's only mistake in an otherwise very well played game. Barsky gives 38. Re1 a question mark and also recommends Ne2 instead in his analysis of the round:

Feb-17-08  stonebrain2006: D. Bronstein vs L. Potucek 1946: a forgotten match?
This game is given by L. Pachman in his book on chess openings (Spanish Opening, Marshall's Attack) After 9.Bxf7+, Potucek played 9....Kh8 instead of taking with the Rook. Of course, Bronstein played 10.Nxe5 and got the upper hand. Now, here Pachman gives up his analysis, so I searched for the complete game in some data base. Well, I can't find it. What I found out is that in 1946, Pachman, Potucek, and other distinguished Czechlovaks masters played two or three matches against Moskow and Leningrad clubs. Young Bronstein teamed up with the Soviet squad. Now, where are the records of those forgotten matches? In Olympic Games Team Matches data base the match Moskow vs Prague is mentioned and even the games are recorded, but the Leningrad Chess Club vs Bratislava's one is barely mentioned, no games recorded. I suspect that this misterious game was played then and there. May be some Czech or Slovak chess friend would be so kind to help us in this research.
Feb-17-08  kellmano: What a game from Chucky. This is why chess fans love him.

Ivanchuk: <Go Speed Racer, go Speed Racer, go Speed Racer, go!>>

LOL!

Feb-18-08  The Chess Express: 8. d4 d6 9. c3 Bg4 is the theoretical solution.

Feb-19-08  notyetagm: <kellmano: What a game from Chucky. This is why chess fans love him.>

Hopefully Chucky will come back from his tough loss to Topalov in the next round.

Feb-20-08  Ulhumbrus: 9 Bxf7 offers two pieces for a Rook. With 10...Rf8 instead of 10...Ne6 Leko declines the offer. An alternative to 11...c5 is 11..Bb7 preparing ...d6 by defending the point c6 against the invasion Nc6. 13..Nxg4?! helps White's Queen to develop. Instead of this, on 13...Bb7 14 Black may have sufficient compensation for the pawn if he can gain a lead in development in addition to the bishop pair.

Instead of 14...d5, 14...Bf6 may give Black enough for the pawn.

On 15...Qh5 the Queen which has been attacked becomes an attacker and the d5 pawn becomes a target.

After 21 Be3 Black has a lead in development, but his QB is blocked by the e pawn. This suggests 21...Qe6 preparing to get the QB into play as quickly as possible by ...Bd5. The way the game goes, Leko does not manage to make this bishop active, and that may be Black's main mistake: not getting the Queen's bishop into play in time.

In this variation, White has Rook+Bishop+5 pawns vs Queen+3 pawns. That's a slight material advantage for Ivanchuk who has 2 extra pawns, one on each wing. I am not sure this is winning but that wouldn't be an easy defensive task for Leko.

Indeed, very entertaining. It's surprising that the world's best can play like this against each other and get away with it.
