You missed the "am" in the epd. That's a problem with this position. The two possible captures are fairly close in eval, so if you happen to pick the bishop move, then you won't see the large negative associated with the rook capture. My fault, not a clear cut situation. Try making the rook move, then see how long to find the +1.5 or so from black's perspective. Will
