How about this one, Loomis (I know it's a draw, I just don't know how):
I know of the skewers and other checks that prevent the black king's approach, and I know that in order to win, black must keep checking the king lest the king guards the pawn on its way to promotion with the rook freed.
That is called the Vancura position.

Titos, you are incorrect.
1. ... Kf7 2. Kf1 Ke7?? 3. a7 and now black cannot prevent promotion without giving up his rook because the white rook will be able to safely move off the a8 square. For example. 3. ... Kd7 4. Rh8 Rxa7 5. Rh7+, or 3. ... Kd6 4. Rd8+ followed by 5. a8=Q.
The correct strategy for black is to sit tight with the king on h7 and g7 and check the white king from the side when it gets near the pawn.
Wow. Thanks. I need to finish my endgame book. That makes perfect sense. I'm sure I'll win a few more games just from knowing that.

Since you are a diamond member, look in the videos here for IM Rensch's series on rook and pawn endings. It should answer all your questions on these positions.
this match is for white

It's white to move and to win. I really need to improve my endgames and this seems like an interesting problem. Thanks for any help.
it is quite simple: the pawn is on b5. Important are now the squares a7,b7,c7. White's King must manage to controle these square (always the 3 squares in front of the pawn, so if the pawn was on another square imaging a T-> pawn is on the food and oposing king the head of the T.
So in this case black already controles the head of the T(a7,b7,c7). There is no chance for white's king to conquer these squares because white can't win the king opposition.
just leave the black rook on a2 and march the king across the 7'th rank towards the pawn and white can't wiSorry, i took another look at it and i am wrong
Get a copy of Paul Keres' classic "Practical Chess Endings". It's essential knowledge, both for amateurs and pros.

I think Kb4 wins.
dude,kb6!
Somehow that post didn't come out right. Basically, what I was going to say anyway is 6.Kb6 wins with correct play.
