Using the row-column labels indicated on the edge of the board, White plays the pawn move c5-c6. To stop further pawn advance, Black captures d7xc6. But this clears the 7th rank, so now White swings the rook across to the opposite corner, Ra8-h8, Black's rook captures White's advanced pawn Ra2xa7, and now White has a "skewer" attack with Rh8-h7 checking Black's king. After the king moves out of check, White will capture Black's rook with Rh7xa7. White has an extra rook for a pawn, which is enough to win the endgame.

Diagram of the skewer situation:

This maneuver of moving the rook to set up a skewer is typical in this type of endgame. To prevent it, Black needed to have his king on g7 or h7.

None of the other moves win. If White plays a king move, Black moves his king to g7, now preventing the skewer. If White plays a rook move, Black's rook captures the pawn on a7, and White has no follow-up.

Is this puzzle from chess.com??

No, but I used chess.com to generate the diagrams. The first time I posted a chess problem, I used the LaTex chess package for the diagram, but that took a lot more time. Also, the LaTex built into the posting on brilliant.org does not support the chess package, so I have to upload an image of the diagram anyway.
