It considers Rxe6 briefly (without a winning score) after about 7 >seconds, then switches to Nxd4, before it finally fails high on Rxe6 after >85 seconds: Better than Zappa, at least. Standard Zappa takes 4 minutes to give a very unconvincing score for Rxe6, while experimental forward pruning zappa needs 2.5 minutes (and still a very unconvincing score). standard: 1. Bf4 Qd8 2.
