5...h6?!
This move seems logical, as Nxf7 doesn't work. However, White can get a slight edge with Ne6! and can win quickly if Black makes a blunder. A grandmaster lost to this trap. The e8-h5 diagonal is slightly weakened, and so is f7. The main line is Ne6! Qb6 (Wisely avoiding fxe6?? Qh5+ g6 Qxg6#) Nxf8 Nxf8 with two Bishops and a slight edge.
