Alekhine Defense: Krejcik Variation
5. Qf3+!

A humiliating checkmate
If black chooses the insanely off-the-table move 5...Ke5??, attempting to defend the Ne4, white can force black to let loose of the knight or embarrassingly checkmate the wandering king with 6. d4+ Kxd4 7. Ne2+ Ke5 8. Bf4+ Kd5? 9. Qb3+ Kd5 10. Nbc3 (or Nec3) Nxc3 11. Nxc3 c6 12. Na4+ Kd4 Qd3# if black insists on defending the knight.
