7... Qh4
Checkmate with Qf2 is threatened. Surprisingly, the three strongest defenses, Qe2, g3, and h3 all give Black a perpetual draw (see below).
8. Qe2 Nd4 9. Qe3 Nxc2 10. Qe2 Nd4 11. Qe3 Nc2
8. g3 Nxg3 9. Nxh8 Nd4 10. hxg3 Qxg3+ 11. Kf1 Qf4+ 12. Kg2 Qg5+ 13. Kf1 Qf4+
8. h3 d5 9. Bxd5 Qf2+ 10. Kh2 Qg3+ 11. Kg1 Qf2+
This makes 8. Qf3 White's most popular move, although Black gains a strong initiative after Rf8 and with plans of rerouting their knight to g4.
