Rook Endgame: King Trapped in Front of the a-Pawn
White to play and win
PlayYour king is stuck on a8, in front of its own pawn, and you win only because his king is cut off on the f-file, too far from c7. The rule: send your rook to b8 to drive his rook off the b-file, walk your king out, and use your rook to shield it from the checks.

The theory
Watch the method: press play to see the winning idea run, or step through it move by move.
Your king cannot move yet: your own pawn stands on a7, and his rook on the b-file covers b7 and b8. If his king reached c7, it would guard those squares itself, and the game would be a draw.
A king stuck on a8 in front of its own a-pawn is the classic drawing structure, but it is not always a draw. The result hangs on one square.
The c7 rule. If the defending king reaches c7 the game is drawn: it sits next to the pawn and your king can never emerge. Keep it out of c7 and you win.
The method. Use the rook either to cut the defending king off (Rc2 here) or to take checking distance (Rh2), then walk your king out to b7 and along the eighth rank under the rook's cover.
In this drill the black king starts on f7, one tempo too slow to reach c7. Cut it off, free your king, and promote.
