I am wondering if any engine likes my ..19 Nxe4! winning on the spot. This was only a 1 min 1 sec game (be kind), and my opponent playing white tried to run. He did not get far! Fun game!

Ng4 wins immediately, but Nxe4 does also work.

I know its winning I was playing black :P . I guess I just wanted to see if any engines thought like a dragon player, who would play Nxe4 on principal almost without calculation. But, it seems Ng4 is just too powerful, a move that did not even occur to me in the 1min time control :wink:
