I don't think this is evidence of "cooking" -- more likely learning.  Quite
likely, they have already analyzed this position set in their database and
therefore know the best responses for each position.

Rather than indicating something underhanded, it probably just means that they
have run extensive testing in this area.  Crafty would do the same thing.  If I
ran crafty at very long time controls, it would update the learning data file
about what to do in these situations.  Is crafty cheating?  Certainly not.  Not
'cooking' anything either.

I don't see any evil conspiracy here.  That does not mean there is nothing
afoot.  But I doubt it.
