"In Cadaquès, Spain, there is a match going on between Deep Fritz and Deep
Junior for the right to play Kramnik. In the fourth game of this match, Deep
Junior - Deep Fritz, there was a strange case of chess blindness. In the
diagrammed position, there followed: 70.Rc6+! White wants to get rid of his
Rook, so he can read his tablebases, instead of think. 70...Kb5! Of course,
Black doesn't want to let him; 'tablebase' is just as bad as 'mate'. 71.Rc5+??
Incredible - he misses a tablebase in two with 71.Rb3+ 71...Kb4! Setting a
cunning trap. 72.Rb5+! Because after 72.Rb3+ Kxc5! there is no tablebase, hence:
draw. 72...Kc4 73.Rd4+ Kc3 74.Rc5+ Kxd4? For some strange reason, Black suddenly
acknowledges he's in a tablebasing net. He could have prolonged the struggle
with Kb3. Now, there followed 75.Rf5 tablebase.
Compare item 61 in this diary. It's like buying a can of beer, then taking the
plane to Zimbabwe because you have a friend there who knows how to open them."
