it's importnat to the 50-moves rule: if you make 50 moves and there is no caputre or pawnmove, the game is drawn.
look for 50-moves rule here in the forums (chess and thisone) or in the web.

So basically if a white rook and king are left against a black king white has 50 moves to check mate if the last move was the white king taking blacks pawn?

If this is so isnt 50 moves a bit much?

EDIT: and oh yeh cheers for the help.

You're right that 50 moves is a lot for trying to mate with a rook. But the rule was really designed for much trickier endings that might be won, such as bishop and knight versus king, or rook and bishop (or knight) versus rook. A lot of these endings are draws with best play, but in practice they're often won. For instance, I believe that the side with rook and bishop wins against a rook in about 70% of cases, although this ending is a theoretical draw. However it takes close to 50 moves to create a mating net.
