Necessary is 1. Rc3 or 1.Kf1, and only after 1...f3 then 2.Ra8, followed by checks on the g- and f-files } ( 1.Rc3 ) ( 1.Kf1 f3 2.Ra8 ) 1...Kg3 2.Ra3+ $4 { The interesting part is that White is not lost yet. By 2.Rg8+ he still has an opportunity to save the game but in a more difficult way, which will be presented later in the book. If you do not know the easy way, do not expect anything better the hard way. Now White's position is totally lost. } ( 2.Rg8+ ) 2...f3 3.Ra1 Rg2+ 4.Kh1 Rh2+ 5.Kg1 f2+ 6.Kf1 Rh1+ { and White resigned. He should not regret the loss of a half-point, since he did not deserve it anyway. } {#R} 0-1
