FIDE World Chess Championship thread

[George]

This thread is for coverage and discussion of the upcoming World Chess Championship between the champion, Viswanathan Anand, and the challenger, Magnus Carlsen, which runs from November 9 to November 26 (not counting the possibility of tie break games). We the moderators are asking you the members to use this thread instead of creating new threads. This does not mean that threads can not be created for topics such as engine analysis of moves played during the match. But, we do wish to keep the general forum from being flooded with multiple threads concerning the match.

Thanks,

I do agree with you.

I cannot say that 27...a6 was winning but at least it was the best way to go to play for it.

During the game, Yasser and partner mentionned that move as probably the best and more importantly the simpler way to play for a win.

It is difficult for me to understand why Magnus didn't play the simpler move 27...a6.

Maybe he is too much of a Genius and lost himself.

That said, it was a great game and both players have played with lots of idea and resources a complicated game.

27... a6 was winning according to my engines on long time control. I put a recent Stockfish as black against Komodo 6, and black won rather uneventfully. I reversed the engines, and Komodo as black won even faster against Stockfish. Not playing 27... a6 was a blunder by Carlsen.

Games: 120 minutes + 60 seconds, on a fairly powerful overclocked 4 core i7:

So much about computers being useless here. Another of Kasparov's wishful thinking.

[kgburcham]

I get up this morning and make my normal internet rounds.
I find the world championship game on move 43 and no posts discussing this game. I also find lots of posts about the Tcec games.
something wrong with this.
seems the message is human low level 2800 vs 2800 is boring compared to high level take chance, go for the win program vs program.
we need another crazy mental 2800 GM like Fischer was---he played for the win.
Oh well I feel sorry for the best human players, other sports do not have machines exposing their true level of play.

[JuLieN]

Anand played Kd5 (SF's best move):

According to SF4, this is yet another draw, now.

Carlsen played Bh7.
[d]8/7B/8/2pkP2R/p6p/PbK5/6PP/3r4 b - - 2 2
It's interesting because, if Carlsen only has draw moves, Anand only has one move that doesn't lose, each time, so it's not that easy for black actually. One mistake and it's lost.

Carlsen played Bg8+ and Anand chose the not optimal continuation Kc6, leading to what SF thinks is nearly +2 for white !

At depth 30 SF4 now thinks that Bxb3 is even better than Rh6+!

But both lines are really around +2 anyway.
