Re: In No castling Chess what Engine would be the King or the best?

Does "no castling chess" have an official variant name? Winboard says it is "nocastle" I suppose. "nocastle" is a Fischer Random Castling variant without castling it seems from trying to get it to play in Winboard. So the question still remains, is there a variant name for standard chess without ca...

Probably "NCC" because it seems Armageddon will be the last variant named by creative people :mrgreen:
How about the Kramnik variant? I am not a big follower of GM Vladimir Kramnik, but he seems to have invented it.

Re: CMH question

Then all the ways of updating such a table. You want shallow depths to update less, as they are more frequent, and you need some absolute bounds to avoid overflows. Testing is key, there is no absolute truth beyond the experimental evidence. The Xiphos formula limits history scoring to a depth of 1...

Re: Polyglot FRC/960 Opening Book

I created a Chess 960 book based on CCRL and ICCF games and it can be found here at the bottom of the Honey-XR7 release.
