Qd4+ wins by any line:
black queen or e pawn interposition is useless;
black king g8 or h7 also fails
1. Qd4+ e5 (Kg8?? Nxh6#. Kh7 Ne7+ is same as main line but 1 move faster)
2. Qxe5+ Kh7 (Qg7 Qxg7#)
3. Ne7+!
Important of course to NOT gain queen with Nd6? Gaining queen is useless in this position.
3. … Ng6 (only legal move)
4. Bxg6#
