if Black plays 38.Px6e, then that continuation would be 39.P2d 40.Px2d 41.Bx3c+ 42.Nx3c 43.Rx2d(orB*7g)

Playing 45.P2d first is important. if Black plays 45.P3e first, then 46.Sx3e 47.Bx3c+ 48.Nx3c 49.P2d 50.P4f 51.Px2c+ 52.N4e. as you can see, P2d could be ignored.

(Text moves) 55.P2d 56.Bx2d 57.K8h

if White plays 56.Px2d, then Black would play 57.N3g. the pawn sacrifice of 55.P2d prevents B1e. if Black plays 55.N3g, then 56.P3e 57.R2f 58.B1e.

58.P8d is risky. White kind of ruin himself.

62.P4f is for 64.N3c. if White plays 62.N3c,white would play 63.P*2e, then 64.B1e, 65.P1f. 66.B5i+ 67.P2d

(Text moves) 65.P6c 66.Rx6c 67.Rx2d 68.Px2d 69.B5b
