Don't dismiss 11. Nxf7!!? as it drives computer evals crazy, but in the end White appears to have a win. This is very tough for computers!

So I decided to post this complex position to see if any program could find 11. Nxf7!!? and follow up sacs. There is a lot to see here, and White can't can't capture the N with the R.

11.f4 seems to win too....

Also after 11.Nxf7 Rxf7 12.Bxe6 Nf8 i don't see a clear win for white.

After 11.f4 comes Nb6 and i don't see a clear win for white.

Yes...that seems to be the Fly in the Ointment as my opponent played 11..Bxh2+ and eventually lost.

11. f4 appears better but 11..Nb6 followed by 12. Bd3 is unclear as well . I considered that move and decided to confuse my opponent with 11. Nxf7. Well I did say tactical insanity It appears that 11. Nxf7, f4 or Qe2 leave White better, not winning.
