2.d8Q Rc6+ 3.Ka7 Rxc4 4.Qde8!
Theme : 4.Qee8? Rxe4 5.Qa8 Sxc3! and, now, White has not 6.Qa3! as in main line : after 6.e7 Black easily draws, eg, 6…Kh2 7.Qxe4 Rxe4 8.Qh8 Sc6+ 9.Ka8 Ra2(b4) =
After 4…Rxe4, White can try 5.e7 Kh2! 6.Qc7 g2 7.Qec6 g1Q+ 8.Ka6 Qf1+ 9.c4 Qf4! 10.Qxe4 Qxe4 11.e8Q Kg2 12.Qexe5 Qa8+ 13.Qa7 Qc8+ 14.Ka5 Qd8+ 15.Qec7 Qd2+ 16.Ka6 Qh6+ 17.Qcb6 Rxb6+ 18.Qxb6 and, eg, 18…Qf4 19.Qc6+ (19.Qxb1 Qxc4+ = Syzygy) 19…Kg3 20.g5 Sd2 21.g6 Sxc4 22.g7 Qf7 =
A sub-variation is (instead of 10.Qxe4) 10.Qe6!? Sd2(a3) 11.e8=Q Sd(a)xc4 12.Qf5 Rb6+! 13.Qxb6 Qxf5 14.gxf5 Sxb6 15.a5 Sbd7 16.Qe7 (16.Kb5 Re1 17.Qc8 Rb1+ 18.Ka4 Kxh3 19.f6 Rf1 20.a6 Kh4 21.Qc2 Rxf6=) and, eg, 16…Ra4 17.f6 Kxh3 18.Qh7+ Kg4 19.Kb5 Rxa5+ 20.Kxa5 Sxf6 =

and White wins after this second Q-sac on e4 followed by a Phoenix-promotion on e8.
