Endgame question

Does white have sufficient advantage to win?

I say yes. Better pawns, rook and king.

How?

What follows is certainly 'a way' you can win it. White basically sacrifices its weakest pawn to move up and promote its best pawn. Black cannot prevent the promotion and has to give up the rook to remove white's new queen. White then exploits the material advantage to win the game.

This was done in Fritz with the end game tablebases. When you start seeing the # signs in the notation is when the tablebases have kicked in.

Hopefully this is not a game in progress.

The ideal place for a rook in the endgame is behind a passed pawn, yours or your opponents. If white can manuever his rook behind the passed d pawn he should be able to ensure victory in any one of a number of ways.
