Right now there is an ongoing chess championship, which (as followers of the sport will know) has been accepted by both major camps as the determiner of the next "world champion". (The match is to be 12 games, and is played in Elista, located close to the middle of nowhere. After 4 games, Topalov has 1 point and Kramnik has 3 points -- 2 wins & 2 draws.) Topalov has just signed a complaint saying that Kramnik is averaging 50 bathroom breaks per game -- and the private, players' bathroom is not monitored in any way. Topalov wants monitoring. (Cf. < http://www.nytimes.com/2006/09/29/crosswords/chess/29chess.html >.) Evidently Topalov is concerned Kramnik may be accessing a chess computer for advice. A.I. QUESTION: Is there a reasonable way, based on Kramnik's play in previous games, to distinguish moves that he conceived solely on his own from ones that are so brilliant that they were probably computer-aided ? --Dan
