"As one stawberry said to the other, if we had not been in that bed together we would not be in this jam today."

[kingliveson]

There is a lot of time now, and the next one to blunder loses. Very delicate and critical position.

Agreed roughly by SF 1.7.1, although on "low power machine" and thus to depth 22 only:

Code: Select all

 22	+0.84	159.7M	2:43.48	h5 g5 Rh6+ Kb5 Ne2 Ka4 Rd6 Qe1 Ng3 Qc3 Rd5 Nc6 Rxg5 Ka3 Ne2 Qd2 Nf4 Qd6 Rd5 Qf8 g4 b3 Kg3 b2 Rd3+ Ka2 Ra4+ Kb1 Rc3 Qf6 Ne2 Qe5+ Kf2 Qb5 Re4

Also Anand is getting closer to time trouble again.

I think that this could be a determinant whether we see draw or win.
