and b). A king and doubled pawns (except rook pawns) win in all normal circumstances. The extra pawn is used only to make a tempo move to gain the opposition (which it can not do if the pawns are on adjacent ranks). Examples With Black to move, White wins by first occupying a key square and then by getting two of the conditions above: 1... Kb5 2. Kd4 (key square) 2... Kc6 3. Kc4 (opposition) 3... Kb6 4. Kd5 (turning maneuver) 4... Kc7 5. Kc5 (opposition) 5... Kd7 6. Kb6 The white king is on the sixth rank (condition c) ahead of the pawn (condition a) and White can advance the pawn. If White is to move, Black draws: 1. Kb3 Kb5 (opposition) 2. c4+ Kc5 3. Kc3 Kc6 Alternatives 3...Kd6 and 3...Kb6 also draw. 4. Kd4 Kd6 5. c5+ Kd7 6. Kd5 Kc7 7. c6 Kc8! If 7...Kd8 then 8.Kd6, taking the opposition, wins. 8. Kd6 Kd8! and Black draws. Kamsky vs. Kramnik This position from Gata Kamsky–Vladimir Kramnik, Nice 2009, was reached after the exchange of rooks in a rook and pawn versus rook endgame. Black draws easily: 125... Ke7 Ke8 also draws. 126. Kd5 Ke8 127. Kd6 Kd8 Taking the opposition. 128. e7+ Ke8 129. Ke6 stalemate.
