This is from Samisch-Reti, Match, 1922. 1.Nf5! gxf5 No real choice in the matter as the bishop on g7 is twice attacked. 2.exf5 Ndf6 Again, no real choice because of the discovered check with f6. But Black is getting a rook and knight for his troubles, so you still need a further plan. 3.Rxe7 Nxe7 4.Ng5+! Did you consider this when you were winning the queen? 4...Kh8 4...hxg5 5.fxg5 Nh5 (5...Nfg8 6.f6+) 6.Qe2 5.b3!! Beautiful, diabolic (just leaves the N on g5) and logical. He's going to put the queen on the long diagonal to apply pressure. BTW, also quite good was 5.Ne4 5...Rae8 6.Qb2 Nxf5 6...Neg8 7.Ne4 Rxe4 8.Bxe4 7.Bxf6 hxg5 8.fxg5 Bxf6 9.Qxf6+ Ng7 10.Rf4 Kg8 11.Be4 Bc8 12.Bh7+ Kxh7 13.Qh6+ Kg8 14.Rh4 with mate to follow as Black can just put up spite checks. Go back to the original set up on your chess board and, now knowing all the moves, see if you can imagine them all the way. Good training!
