I agree that Steven's suggestion could detect the case where someone >takes Crafty and changes just the name, but I disagree that that is useful. It is useful(I do not know how much it is useful in world championship but it is useful in WBEC when people do exactly that or almost exactly that). Cases that I remember at this moment Luiza=Faile OldBlindDog=Arasan Deep9=Pepito Syboney=pepito with different evaluation. I am not sure about spelling syboney but clone does not deserve correct spelling I suspect that the number of cases that people did not find out is even bigger. Uri
