There are also a few programs that play it already, giving some basis for comparison. Due to the drop rule, which results in a huge branching factor(100-200 being common) it is hard for the programs to search deep enough to win useing the search methods common in chess. Also, the game never simplifies to an endgame with few pieces like chess does, makeing endgame databases impossible. Currently the top crazyhouse players can *reliably* beat the top programs, even at fairly high speeds(3 0 commonly) Whether the crazyhouse programs will be able to catch up or not remains to be seen, I think that they will, but it won't be easy. I encourage everyone here who has a chess playing program to try modifying it to play crazyhouse, and see how it does :) Angrim >The brain is my second favorite organ.
