Chess Opening Theory/1. e4/1...e5/2. Nf3/2...Nc6/3. Bc4/3...Nf6/4. Ng5/4...Bc5/5. Nxf7/5...Bxf2/6. Kf1/6...Qe7/7. Nxh8/7...d5/8. Kxf2

8. Kxf2
Black should now capture with 8...dxc4. A common mistake is Nxe4+ first, but after Kf1, White will be able to safely trade queens and play the game with a comfortable position.

After dxc4, Black will move out all of their pieces in an attempt to checkmate. However, with their deficit in material and solid defense by White, Black cannot force a win. They do, however, have many ways to attain a perpetual check and draw. (See the example game below.)

One trick White should be aware of is Black's potential knight sacrifice on e4. For example, after 9. d3 Bg4 10. Qd2, Black has 10...Nxe4!? because after 11. dxe4 Qh4+ 12. Kg1, 12...Rd8 threatens the dangerous Rd1 if the queen moves.
