As Predicted ... 8-)
This is an interesting position for Gaviota. It is continually changing among several options. I have never seen such doubt...
Gaviota does not feel comfortable with black. Sounds like most moves are waiting moves and everything else will mess up the position.

So sacrifice after 135M nodes, let's see if Anand goes for this Nh6...
Looks like strong as hell.

This is almost decisive. Anand in lead. Nice game.

This 'doubt' is normally happening to ChessMind all the time, but not in this position... :D

25.e5! does now win. I hope that Anand is going to play this, but I don't believe he is going for a draw in a position like this and e5 is not very difficult to see, but only difficult to calculate completely. :)
