"GP: I hope you have time to make some notes on the Fabiano Caruana vs Magnus Carlsen game."
The trick is not to look at postions and games where you are on thin ice.
(ie.don't know what you are talking about.)
Here. (I see some of you lot are posting analysis without diagrams
again...pointless, especially when there are two games posted back to back.)
Carlsen played 24....Kc8 and after a few minutes Caruana played 25.Nxc7.
Black cannot take the Knight due to the discovered e6+ check which slaughters him.
Black played 25....Kd8 within seconds of White playing 25.Nxc7.
(ah-ha - it's what Carlsen wanted.)
I post on chessgames that this is a pawn sac to give the e7 Bishop some
squares on Queenside. Club players would never play such a sac and stay
with a bad Bishop etc....blah...blah...bloody blah.
In the after game interview Carlsen admits his 25th move was a blunder.
So I'm OK with under 2000 games if it's tacticl and blunderful.
Over that and I'm on thin ice. So although it is flooded with wee tricks
and traps towards the end and I reckon given a whole day I may be able
to note up 80% of it fairly well, I think I'll leave this one alone.
Here, White to play.
".....why does White not take the unprotected f7 pawn on move 38/39?
That would have given White a connected passer. He shillyshallies around
and picks it up on move 42."
White was in severe time trouble here - very severe.
He reached move 40, nulled all the threats and took the pawn.
ghost variations, sound and unsound would have running running through his mind.
He is an unsound one, that turns into a mess if he takes the pawn.
White was making moves in seconds. You do see or sense these things
when you are winning and time is low.
Carlsen has stopped the rot and won his next game.
