I agree with the Seattle Chess Federation. ...Nf4 does nothing to block the
advancing white pawns, and after Rxf4, Kxf4, now the black king is also drawn
away from the critical square it now occupies to stop those white pawns. The
sole good point of ...Nf4 is that it brings his Bishop back into active play,
but of course, ...Nf6 does this just as well while _also_ blocking another white
pawn, and attacking still another square that white's pawn must traverse.

I'm sure Black would agree he was asleep at the wheel on this move, and wouldn't
play it again. I still trust the human eye to see the thematic continuations
better than the computer when tactical shots are not near.
