This position is taken from an ending Capablanca analysed in one of the last lectures he delivered just before his death in 1942:
1... Rf4 2.Kd3 Rf3+! [simple enough to find but very effective. This move destroys the kingside pawn formation.] 3.gxf3 Rxg1 [Black now wins the h-pawn and the game after 4...Rh1.]
