it's top options.
8 plies +0.02 1.Qh4 h5 2.Ne4 Bb7 3.Rd1 Na6 4.Bf4 c4
9 plies +0.38 1.Ne4 a6 2.Nxd6 Qxd6 3.Bf4 Nbd7 4.Bxd7 Rxd7 5.c4 Qxf6 6.Qxe5 Qxe5
7.Bxe5
10 Plies +0.84 1.Nxh7 Kxh7 2.Qh4+ Kg8 3.Bh6 Bg4 4.Bg7 Bh5 5.Qg5 Ng4 6.h3 Qc8
7.hxg4 Bxg4
11 plies +1.10 1.Nxh7 Kxh7 2.Qh4+ Kg8 3.Bh6 Bg4 4.Bg7 Bh5 5.Qg5 Ng4 6.h3
