With Yace, you'll need some patience, but it will at least come up with the
correct move after a while. I guess "passed pawn pushing extensions" could help
here much. Also, there might be some null move issues, but I am not sure.
Anyway, after 40 minutes Yace switches to Nxe4 again with slightly positive
score, and after 2h+, to a winning score:

I guess, with more patience, Mat16 (as reported by Franz) would be found, too.
