I certainly can't do it... I tested this on Rebel 8 and it sticks with h4 from start to finish. I'm guessing a knowledge solution is at play here as the opposite King castling typically calls for pawn storms against the king. I entered Bxe7 manually to see what Rebel 8 does but the eval is about 0.60 less than h4. after black's Nc4 it replys with Qd8+ with an eventual perpetual check line.
