It only uses the 6 piece databases, has some search enhancements disabled, and conducts much more shallow searches than the tournament version. I will make a resolution to update the Wall more frequently in 2001. Please let me know if I made any omissions. Usually the longest games are those that Chinook does not win.
Chinook always treats every move the same and tries to win every game fairly.
Because of the above, please note playing Chinook over the web is not the same as playing a game on your home computer. You may select one of three levels - novice, amateur, or intermediate. The amount of CPU time used by Chinook increases for each level. After submitting your move, Chinook should respond within a minute or so. Please be patient - response time depends upon network load, the load on our server, and the level you selected.
