Gligoric-Smyslov, 1959

Almost there.

My conscience bites me a bit that I play here and there, the reading public, if any, might be appalled and already concentrated all its attention to the very interesting Komodo-SF match, run by Graham, but what to do, Carlsen plays like that.

Sorry to our many viewers for the delay. Stockfish plays Qe2.

Whatever you plan to unleash, Stockfish is blind to it. Evaluation is 0.00 at depth 50 (with 6-man tables).

This is from a very experimental version of mine. Much lower depth because of some changes in the search. No eval changes.

Which sees even less for Black than my standard SF did. But Lyudmil has stunned us before ...

Well, Jörg, if I have pasted this correctly after the last but one already made moves the variant of your version is buggy at least for the end of it.
70.Bb4? would be answered by ...Nxd4! instead of 70...Rxa2? and 72.cxd4? by ...c3! with a winning eval for Black whilst 72.Rb2! instead still would be equal

SF plays Bxe4, still thinking it is heading for a draw.

This is a known problem.
The farther away from the root position, the less reliable the PV gets. Nothing new.

Of course, there is always the possibility I broke something accidently ...
