After 1.f6 Nxc4+ 2.Ke1, here is what CM_SKR says on a P4-2.4: Time Depth Score Positions Moves 0:00 1/3 1.24 5822 2...Bxf6 3.Qxf6 Rxe4+ 4.Kf2 Qd7 5.fxe4 gxf6 6.Ne7+ Kf7 7.bxc4 0:00 1/3 0.71 6841 2...Qd7 3.Ne7+ Kh8 4.bxc4 Qxa4 5.Rxg7 0:00 1/4 0.70 19569 2...Qd7 3.bxc4 Rxa4 4.Ne7+ Rxe7 5.fxe7 Qxe7 0:00 1/4 0.60 22690 2...Qc7 3.Ne7+ Rxe7 4.fxe7 Be5 5.e8=Q+ Rxe8 0:00 1/4 0.14 33347 2...Ra7 3.Ne7+ Raxe7 4.fxe7 Be5 5.Qg4 Bxg3+ 6.Qxg3 0:00 1/5 -0.18 111820 2...Ra7 3.Ne7+ Raxe7 4.fxe7 Be5 5.Qg4 Bxg3+ 6.Qxg3 Ne5 0:01 1/6 -0.03 261186 2...Ra7 3.Qxh6 Rxe4+ 4.Kd1 Ne3+ 5.Kc1 gxh6 6.Ne7+ Kf7 7.Nxc6 0:08 1/7 -0.37 1498065 2...Ra7 3.fxg7 Bxg7 4.Nh4 Ne5 5.Qf6 Kh7 0:23 1/8 -0.35 4246915 2...Ra7 3.Ne7+ Raxe7 4.fxe7 Be5 5.Qg4 Bxg3+ 6.Qxg3 Ne5 7.Nc3 Rxe7 8.Ke2 0:42 1/9 -0.06 8150463 2...Ra7 3.fxg7 Bxg7 4.Rhg1 Rf7 5.Qc1 Rxe4+ 6.fxe4 Qxe4+ 7.Kd1 Qd4+ 8.Ke1 Qf2+ 9.Kd1 2:01 1/10 -0.18 23947725 2...Ra7 3.f7+ Rxf7 4.Qxh6 Rxe4+ 5.Kd1 gxh6 6.Ne5+ Kh7 7.Nxc6 Ne3+ 8.Kd2 Nf5 9.Rg6 Rh4 10.Rxh4 Nxh4 11.Nxd4 Nxg6 12.hxg6+ Kxg6 5:32 1/11 -0.15 67075003 2...Ra7 3.fxg7 Bxg7 4.Nh4 Ne5 5.Qd2 d5 6.Qxd5+ Qxd5 7.exd5 b5 8.Nc3 Nxf3+ 9.Kd1 So, apparently there might be a big question as to how White should respond after 2...Ra7. The King sees four different possibilities (Ne7+, Qxh6, fxg7 and f7+), although the scores for all of them slightly favor Black. Here's the position after 2...Ra7 that probably needs a LOT of analysis: [D]4r1k1/r5p1/1pqp1PNp/2p4P/N1nbPQ2/1P3PR1/P7/4K2R w - - 0 3 jm
