Some nice numbers about crazyhouse (aka drop-chess). branching factor = +- 102 estimated depth needed for dominating human players (3 0 games): 9 ply raw alpha-beta nodes needed per move: 102^5 + 102^4 - 1 = 11149051247 nodes current program speed: 60Knps on an AMD-K6-400 assuming 5 seconds per move (normal for 3 0): 300000 nodes Todays (common) computers are thus 37163 times too slow. Assuming that speed doubles each 18 months, we need 15,18 x 18 months = 273 months = 23 years. So it will take at least 23 years before computers reach a level comparable to humans for crazyhouse chess. This is of course an estimation, ignoring forward pruning and other alpha-beta enhancements, but it gives a nice impression why we still need faster hardware ;) -- GCP
