Yes, with best play on both sides it should be a draw.

Maybe I'm wrong, but this doesn't look like a draw to me. Black should win.

What a position looks like is not evidence, only what it plays like

Here Black cannot make progress with best play unless White foolishly takes the g-pawn or moves the K. Then Black wins. White's R remains on the a-file unless checking safely. Neither side can change the position to their advantage.

Perhaps it's worth posting the ways that White can lose from this sort of position.

Basically there are two traps. In the first one the defending side allows a skewer:



Obviously if White doesn't capture the pawn after 1. ... Rh1 then Black will play a1=Q next move.

The second way that the defending side can lose is to allow the rook to move away from the queening square with a tempo:




As long as White avoids walking into these two traps the drawing technique is quite easy. In the example in the original message, White will simply move his rook between a7 and a8, checking the Black king if it moves to b2, trying to defend the queening square. If the Black king moves up to attack the rook, White just plays it down to a3.

The diagram is from white's view, so there is no h7-h5 😉

I this position i put a check when the king is protecting the pawn. And continue to do until the king the rook as the only defender.I am not sure BUt I think black would happy to switch his rook and king of places.

Fat lady is correct.

As it is black to move, simply ... Rg1 wins. If you require the moves please advise-there may be a hole.

Never mind...misplaced the white rook.

Do you mean I'm correct when I say that the original position is drawn with best play on both sides?

1. ... Rg1 fails to 2. Kxg1. Although Black has vacated a1 for his pawn, he has lost the rook which prevented White from capturing it as soon as it promoted. Play would probably continue 2. ... Kb2 3. Rxa2 Kxa2 4. Kxg3.
