It's time my lame engine learns how to detect draws that are not

Repetition: That's the same position for the third time, right? So I
keep a history of hashes, and search it each node for 2 hits.

I believe you only need to test for a single repetition to count it as
a draw. Even though the rule states a third identical position, in a
search tree a single repetition produces the same result.
