Hello Vincent, I talked with some wild5 expert a while ago about why computers can't play it very well. It is very similar to the problems we face in crazyhouse (you know the game where you can place pieces you captured from opponent - bit like Shogi). One thing is the obvious high branching factor, another big thing is that games are much more decided by mating attacks, and sacks of whole pieces for a tempo or two are common. Now bots completely freak out when you have poseval() function which can reach +-500 pawn units (at least thats what happens to me) so they do not see that some of the good wild5 opening lines for black include a knight sack very early when it is not forced already. Wild5 might well be a win for white theoretically like normal chess might be a draw. But prove it ?! Bah. Regards, Georg (Tecumseh @ Fics , TRT @ ICC)
