I played this today on ICC, G/25. This illustrates what to do when you have an Isolated Queen's Pawn, and when your opponent does nothing to stop you: you put your rook behind the pawn, and push it down his throat.
I have added a handy little tool to generate diagrams from FEN positions. For example, if you are using WinBoard, click File->Copy Position To Clipboard, paste it into the FEN Position text box on the right of this page, and then click Create Diagram. A URL will be generated in the textbox underneath, which you can copy and paste. If you want to display the diagram as an image in your blog, check HTML and it will return an IMG HTML tag.
In an embarrassing earlier post, I said "once the pawn reaches the 6th rank, a draw is forced once the king reaches the queening square." WRONG WRONG WRONG WRONG
