[Anil]

Is Anand doing this deliberately ... to give Kramnik some hope?

I am sure after this game, Anand will re-work on his chess tactics.

Most are happening after move 30, so it may also be a physical conditioning problem.

Yup! You may be right. Anand must have sensed that he is winning clearly and is becoming complacent. Good to know... so that he has some room for improvement. Hope it is not due to physical conditioning problem.

[rlsuth]

Anand blundered! 41. Rxg7+! wins easily.

I'm probably being pedantic here, but I've always thought of a blunder as being a losing move and that this is just an inaccuracy.

Playing fxg7 instead of Rxg7.

I am sure after this game, Anand will re-work on his chess tactics.

.... Kg8 played.

Looks like both these Super-Grandmasters are making big big blunders almost every single move according to engines...

Terry, so you still think GM's are better in timed games?

Couple more of these and you too would be proven correct

[Uri Blass]

Yes, Kramnik made several poor moves. Anand should go on to win easily.

Kramnik is out of this match.

Well, Anand do make blunders as well... fxg7 is not so good move.

Engine thinks white is now at +2.37.

Anand missed the easy winning move.

It is possible that anand calculated a different win and I doubt if you can call
his move blunder.

There may be more than one correct move.

I'm probably being pedantic here, but I've always thought of a blunder as being a losing move and that this is just an inaccuracy.

It appears that the new definition of a blunder is "move that causes a severe score drop in engine analysis (more than 1 point drop)"

[swami]

There may be more than one correct move.

Uri

Ofcourse, but the gap in evaluation score between the one Anand made and the one the engine thinks is very HUGE ~ by almost +4.0 score difference! (which btw is equivalent to minor piece and a pawn)

[Anil]

It is possible that anand calculated a different win and I doubt if you can call
his move blunder.

There may be more than one correct move.

Uri

Looking at how things are going, Anand seems to be searching for a clear path to victory here... with Kramnik showing a Never Give Up attitude.

[Albert Silver]

Uri

I tend to agree. It is not much different that a test position in which the engine discovers an alternate win, that is not quite as accurate the desired solution.
