Anand vs. Gelfand WCC 2012 started

[Uri Blass]

INCREDIBLE!!!! Now that's exciting!!!

A miniature game in a world chess championship!!! That was a superb reaction by Anand, and Gelfand couldn't stand the pressure of being in the lead. Amazing!!!

EDIT: Thx for posting the game, Robert.

Exciting, but equally sad that a game with so much potential was ended by a stupid blunder.
Anand will be delighted, for the rest of the match Gelfand will now have doubts about his tactical computations.

Robert

It is a tactical mistake but I do not call it "a stupid blunder"
A stupid blunder is something that most strong players are not going to miss even without an engine.

Yeah the live commentators (both being GMs) also missed the queen getting trapped.

Since Kramnik missed a mate-in-1 it's hard to call anything an incredible blunder...

My opinion is that if most strong players understand that a move is a mistake at real time without an engine before seeing the refutation then it is correct to call it a blunder.

I believe that it is the case for the mate in 1 that kramnik missed against Fritz.

[Guenther]

I think Qf6 is a tactical mistake,QxRh1 is a blunder because you hung the queen.

We all know by now that Qf6 was a tactical mistake no need to repeat it,
as it was already said in the thread. Moreover Qxh1 was no blunder and does
not hang a Q it was just the consequence of Qf6, but White remains with a
lot of attacking power and by far better position. Still it seems Gelfand
resigned too early and was somehow shocked by Qf2...

I don't think Nf6 is necessary maybe first Rf1 or hxg6 hxg6 Rf1 and later h4.. White looks clearly winning but maybe not immediately.

I believe that at the level of strong GM's it is clearly winning and white does not need to play 19.Bg2 and can play also 19.Bd3

I believe that at the level of strong GM's white wins with probability of 99% after Qf2 even if black continues the game.

There are positions that computers evaluate as winning but humans have good chances to go wrong but it is not one of these positions because black has no attacking chances.

Quazar reminds me a lot to SF, but +3 for white should be enough at top level in this position; I am a patzer and I have not got the skill to evaluate it seriously. Good luck with DoubleCheck/DiscoCheck!

If he only "miscalculated", he may have actually known that his queen would get trapped, but there was an oversight in some other detail.

I believe that at the level of strong GM's white wins with probability of 99% after Qf2 even if black continues the game.

Not perhaps only 90% probability and he could have tried for a draw? (but had too much pride, as if to admit that such a mistake was acceptable for him)
