the triplejump website claims to review 'ALL' available draughts programs, but
there are two points about the list:

1) these are not reviews. what they write is just what they read on the websites
of these programs. no original input. more like a commercial break...
i've really looked at a lot of these programs, and i often disagree with their
ratings.
2) the strongest free program is NOT on the list - incidentally, it's mine :-)
it's called checkerboard, and you can download it on www.fierz.ch/checkers.htm

checkers programs are much better than chess programs if you compare them to the
best humans. two reasons: they can search much deeper because of the low
effective branching factor of about 2 per ply, and there are 'better' endgame
databases available for checkers (schaeffer is giving away his 6-piece database.
not the 7- or 8-piece db though). 'better' because nearly ALL checkers games
between strong opponents end up in such endgames, while in chess you mostly do
NOT end up in the tablebases.
on a technical level i am pretty sure that chess programs are much better than
checkers programs. there is no championship in checkers which would make people
more competitive, too little programs on the market, and not much money to make.
my program is one of the strongest, and i don't use any special tricks and i'm
neither a programming wizard nor a checkers expert. i just did checkers because
it's much easier to program than chess :-)
