The famous study: White must escort the c-pawn through a storm of rook checks, avoid the stalemate trap, and underpromote to a rook to win.
This is the best-known study in chess. White has only a pawn against a rook, yet wins.
Common mistakes
- Kb7Too slow: 1...Rd1! and 2...Rc1 ties the pawn down for good; the king can never leave its side and White cannot promote. Drawn.
- Kc7The king blocks its own pawn; after 1...Rd1 and 2...Rc1 the pawn is permanently tied down. Drawn.
- Ka6The king abandons the pawn: 1...Rc5 and the pawn falls. Drawn.
