Alekhine Defense: Krejcik Variation

[edit | edit source]

5. Qf3+!

[edit | edit source]

White still manages to win the piece back and will be able to attack Black's incredibly unsafe king on F6.

A humiliating checkmate

[edit | edit source]

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.
