Subject: Computer chess vs. computer checkers and other games

I'm curious if anyone knows anything about the computer checkers scene. I know
about computer chess, how chess programs work, how good chess programs are
compared to the best human chess players, etc. and would like to find out about
checkers programs. I know that (for example) go programs aren't anywhere close
to master strength. So are checkers programs as good as the best master checkers
players? I would guess that checkers would probably use some of the same basic
methods as a chess program, such as search and evaluation, but are there any
special methods that a checkers program would use that chess programs don't? Or
any methods a chess program uses that a checkers program wouldn't use
successfully?

I've only recently started playing checkers to get a feel for the game, but it
seems like there are a great number of positions where zugzwang occurs and so
null move probably wouldn't work in checkers, or maybe it would need
modifications. I'm mainly interested in checkers programs and that whole
"scene", but also if anyone has any info to offer on other game playing programs
I'd like to hear that as well. I'm more a fan of game playing programs and AI
methods in general than only chess.

One last thing I thought about was endgame tablebases. Are these available for
checkers or other games? It seems like it might be both faster and smaller to
generate the tablebases for checkers, but I'm not totally sure on that. There
are fewer pieces on the board and fewer squares of the board that are in use, so
it seems like endgame tablebases might play a more significant role if they were
created for checkers.

Thanks for your info.
