Protected Passed Pawn Chess Puzzles

A protected passed pawn is a pawn that has no opposing pawns in its way (passed), and is also defended by a piece or pawn so it can advance without being immediately captured. For example, in many Queen’s Gambit structures, a pawn becomes passed after exchanges on the c- or d-file and is then supported by a rook or king to keep it alive. The key feature is the combination of “passed” status plus “protection,” which reduces counterplay.
