The idea Nf5 is nothing special.
However even if you find that idea in a blitz game you usually would lose much
more time. You have to check whether white has any tactical options on the
a1-h8 diagonal or not.
You might also think about what happens if white simply retreats his bishop to
f2.
3 seconds for that move is pretty fast.

It is not a clear evidence of cheating however.
