It doesn't have to be obvious, could be KRNKR.

Anyway you never know, nothing wrong with making a rule about it. Get it down on

My opinion is the game is over when the program hits table bases, from there on
it can't lose a non-lost position. Only reason to continue would be to wait for
Kaspy to make a mistake, that is lame IMO.
I don't really see how Junior could take the credit for such a win anyway if it
was _only_ due to the tables.
