Sounds interesting Will! About this position, I tried many variations of Pro Deo
settings on it. I don't believe I have seen this particular variation yet by Pro
Deo, with Qxa3-c1 followed by a3! Looks like the human way to try to force a way
through for the a-pawn!

Standard Fruit actually takes about 25 minutes to play e5:
