It seems to contradict what Hsu & Campbell say, unless you make the improbable assumption that the interface asked for time control and then emulated it while really thinking only one second (what for ?). It's more probable that they weren't directly involved with setting up this demo and were misinformed about its capabilities. >>I wouldn't consider Rebel beating DBjr a surprise. Even assuming full-DB to be >>the equal of Kasparov (doubtful), DBjr should be much weaker, and not more than >>Rebel.
