What do you like about checkers?: I like checkers programming, most notably Perfect Play Databases for the endgame.

8-Piece Perfect Play Database Solved

Post by Ed Trice »

I finished solving all of the 4x4 endings with Perfect Play. The longest win is 293-ply.

I can now instantaneously show the quickest wins and strongest defense to any 4x4 position.

I also probed the databases for things like the longest win in a bridge ending and the longest win with 4 checkers against 4 checkers where one side didn't move any pieces yet.

Dear Ed,

Will this perfect play db (8 piece) be made available to use with WCC Platinum?

I find these dbs phenomenal: we've always known that checkers was beyond human mastery; these emphasize that point to the nth degree.
