As in the example with the b-pawn, White may win even when the black king is cut off only a file away from the pawn, provided that black pieces have not reached their optimum-positions Rc8 and Ke6, i.e. Ke5. The following position has been examined by J. Nunn in 1992. Black to move may easily draw in as many as three different ways. The simplest is 1…Rd8 2.Rxd8 Kxd8 3.Kb4 Kc8!, but also good is 1…Rb8 2.c5 Rd8. It is important to know that Black draws also by placing his king in the optimum-position 1…Ke6 since after 2.Kb4 Rb8+ 3. Ka5 Rc8! 4.Kb5 Rb8+ 5.Ka6 Rc8! White cannot strengthen his position. If 6.Rc1 there would follow 6…Kd6, and if 6.Rd4 there follows 6…Ke5.
