[S.Taylor]

YES, it IS the end of an era, probably.
I would have prefered just one more time for Anand, (and who knows, maybe even Gelfand would have managed next time,) and then, we could have our new era!

After a great kingside attack by Anand, 28.Nf1? instead of Bf1 suddenly lost the game. Carlsen will certainly make at least 0.5/3 in the remaining match games, thus becoming the new World Champion. And I am sure, Anand will remain the wonderful player that he is, on the highest level.

It is sad to see a player of Anand's calibre crash 'n' burn after such a strong attack.

Yes but we must remember that Anand is a very very old man - past

40 years of age no doubt... It's not so easy to play topchess then...

It was an fascinating game, but it does seem that Carlsen had it all calculated accurately and if anything after white's attack fizzles out it is black that holds the advantage. But Anand should not have lost that game, and a draw would have been a fair outcome.

You're right, Anand shouldn't have lossed this game. 28. Nf1?? Ouch!

Hello:

Anand must win the rest of games (two of them with black pieces) to get a drawn match and go into the tiebreaks. If I maintain the same parameters than other times:

Code: Select all

White advantage:              40.0 Elo.
Supposed rating difference:   47.0 Elo.

          100000000 simulations:

Carlsen wins:             99966966
Anand wins:                      0
Drawn matches:               33034

Approximated elapsed time:   67.45 seconds.

99.966966% + 0.3*0.033034% = 99.9768762% ~ 99.98% for Carlsen after 1e+8 simulations; in other words, around 1/(4324.5) possibilities for Anand! I was curious about the estimates after the result of +3 -0 =6 in favour of Carlsen, this is why I write this message. With my parameters, I theoretically obtain a probability for Anand of more less (0.7)*[(0.04841010295005)²]*(0.140069588935) ~ 1/(4352.0) ~ 2.2978e-4, which makes sense with the obtain result after 1e+8 simulations.

Well, you have to add to your estimations the possibility of Carlsen dying in next hours before match definition. Very unlike, but I'm afraid its only Anand really possibility to keep the title. And still not sure what rules say in such extreme rare case.

Anand in press conference, for me, does not look angry as before, all opposite, probably a sign that he maybe has accepted the end as WCC.

Hello again:

Well, you have to add to your estimations the possibility of Carlsen dying in next hours before match definition. Very unlike, but I'm afraid its only Anand really possibility to keep the title. And still not sure what rules say in such extreme rare case.

Anand in press conference, for me, does not look angry as before, all opposite, probably a sign that he maybe has accepted the end as WCC.

Of course I was assuming a normal end of the championship: no sudden deaths, no kills, etc. Crossing fingers to not reach this extreme case of 10^(-7) probability or such...

------------

Yep, if an and had played Bf1, Carlsen had only one move to draw the game : Qd1.

Sure, but this move should be very easy for Carlsen: I am an unrated player (but surely below 1800 Elo FIDE) and 28.- ..., Qd1 seeking 29.- Rh4, Qh5 was the only move that made sense for me without engine analysis, and it was instantly. Will not a 1000 to 1200 Elo player stronger than me see this move?
