Post by Eelco de Groot »

I let Toga Checkov run longer, on the game position, not on George's altered position, and after a deep search it finds Tal's sacrifice be it with a different move-order, first sacrificing the Bishop. But I counted that as correct, the outcome is the same. I'm glad it did not completely lock out the move with the other alternative good moves. Found after 100 minutes on an Athlon so not very fast.. It is an experimental settings-version of Toga Checkov just made though, for this position so I don't really have an idea how good this Checkov version is compared to other Checkovs. Some other versions could not find the sac-moves and stuck with c4 for at least 20 minutes, so I think they would do about the same or worse.

Quite hard for engines, yes.

Domestic SF6 didn't find it after 2 mins at PV=15. Even after manually plugging Rf6 it took like 30 secs to realize its winning.
