But backtracking again, Houdini gives the defense 1.Qf4 h6 (instead of 1. Qf4 exf4 ) and Houdini no longer sees Mate, even after many hours

You are right, Louis !zullil wrote:The original problem was White to play and win, not White to play and mate in N.
My only point is that after 1. Qf4 the "best" (longest) Black defense is not ...exf4 but ...h6
