That's a tough one, for a lot of engines.  As an experiment, I added a little
code to return a draw score if, during any search, there appears to be a
"pseudo-repetition" (a series of pointless checks).

The standard Amateur doesn't find e5 in 10 minutes.  The experimental one finds
it almost immediately.  This is probably an anomaly, but it does work in some
situations.  I'll have to look into this some more.
