Aloha!
I just made a new version of CheckerBoard available for download. CheckerBoard 1.72 fixes some minor issues, and comes with new versions of Cake and Suicidal Cake. Mostly, the improvements are just bugfixes. Ed Gilbert contributed to this release (and motivated me to fix some more issues) - thanks, Ed!
As usual, you can download CheckerBoard on http://www.fierz.ch/checkers.htm (where you can also find links to my program's latest excursions to iPhone, Android phones and the Amazon Kindle).
happy Easter!

Re: CheckerBoard 1.72
and a PS: I just uploaded the 64-bit version of CheckerBoard 1.72 along with all associated 64-bit versions of the engines. For those of you using new PCs with lots of RAM (>2GB) and 64-bit windows, and my 8-piece database or even Ed's incredible 10-piece database, the 64-bit version is a "must".
Download from http://www.fierz.ch/checkers.htm as usual. And thanks to Ed Gilbert, again as usual, for giving me a hand with the 64-bit compile!
cheers

Re: CheckerBoard 1.72
Hi Martin. Thanks for all the great work. Is there a known comment length restriction with checkerboard? I'm trying to paste the following PDN into the 32-bit version of 1.72 and when I get to move 16 (the one with the ridiculously long comment) it crashes checkerboard.
