Can you draw this position?

    I would imagine USCF rules would be specific enough to state that mate must be impossible regardless of the play of both sides -- I'm not sure what else the definition would be. The given position doesn't meet that definition because mate is possible depending on how both sides play.

    Whether a king and knight will be theoretically enough material to mate will depend on the position the other side has.

    Here's an example of FIDE ruling that white's clock in this situation would not be a draw. https://en.wikipedia.org/wiki/Monika_So%C4%87ko#Rules_appeal_in_2008

    It seems like USCF policy is different, and is somewhat controversial.  It requires a forced win.  That means 2 kings and 2 knights is a draw if time runs out, unlike the FIDE ruling above. Still, the puzzle I made would be a win for black, but only because a win is forceable. https://en.wikipedia.org/wiki/Rules_of_chess#Timing

    So I was wrong: white to play and lose, not draw.  Except on live chess on the internets. End thread.

    A thorough refutation, at least over the board. All of white's legal moves lose.

    1.a4 Nc2#
    1.Na4 Nc2#
    1.Nb5 Nc2#
    1.Nd5 Nc2#
    1.Ne4 Nc2#
    1.N3e2 Nc2#
    1.Nd1 Nc2#
    1.N1e2 Nc2# (1...Nb3#)
    1.Nd3 Nc2# (1...Nb3#)
    1.Nb3 Nc2# (1...Nxb3#)

    So there must be some trickery going on off the board...
