1.-Nf2+ 2.Nxf2 Bf3+ 3.Qxf3 Qxf1+ 4.Kh2 Bd4+ looks strong 🙂

7.Nf2 Bxf2#
There are so many sub variations which I have not loaded.
Mate in 7, I think, starting with 1. …Nf2.
However, there are many variations at move 2 and 3 for white, and I might be missing the longest line, but the one I see starts with
1. …..Nf2
2. Kh2 Nh3
3. c7 Be5
4. Kg2 Nf4
And I don’t see any of white’s three moves from this point surviving beyond move 7.
oops got the board upside down, thats a problem for lazy old guys 🙂
