After 7. Kxc7, I get a draw score until depth 62 (the maximal search depth).
It does not make much sense to show the PV, because, when the draw is seen, no
effort is made, to give the opponent a hard time.
I wondered a bit, about the high search depth. It seems, that the HTs fill with
the relevant part of a KPPKPP endgame TB (KPPKP was available). To exclude some
stupid errors, I also disabled all pruning rules - with the same result.
Thanks for you other comments.
BTW. I'd like to be able to do more blindfold. Especially reading games
blindfold would be a nice "feature" for a chess programmer.

Dieter
