the approach with neural nets can be plugged into a standard alpha-beta search,
using the neural net as evaluation function. recently, david fogel and kumar
chellapilla used a genetic algorithm to evolve neural networks to evaluate
checkers positions. they made a bit much hype about it ("learned to play
checkers!" (only learned to evaluate - the search part also belongs to playing
checkers) "defeated a commercial program!" (yeah, one for kids...)), it is a
weak program, mainly because the neural net is very slow in evaluating. but it
plays a much better game than a program which only evaluates material and got
something like a 2000 rating on the MSN zone.
and on the whole, the approach is very interesting, because today's forms of
machine learning used by chess programs are rather poor.
if you want to read on the program:

there is also a book by david fogel, it's a good read, but not very technical -
probably nothing for the average CCC member.
