Clash is entering its first ACM tournament. The program is written in [[Fortran|Fortran IV]] by [[Chris Peters]], a student at the University of Washington. It requires 10k for instructions and an additional 4k for the tree search. The program searches a highly [[Selectivity|selective]] [[Search Tree|tree]] and examines about 1,000 - 2,000 positions per move. It uses the [[Alpha-Beta|alpha-beta]] algorithm and the [[Killer Heuristic|killer heuristic]] but does not employ [[Iterative Deepening|iterative deepening]].
