Draw ... or can white win?

All that said, I think we can conclude that your opponent resigned a bit early -- there was a lot left to prove :-)

 I'm sorry, I meant Kh4.

I couldn't agree more! There was a lot more to that endgame than I thought, and it certainly went down lines I hadn't considered and would not have found with the clock ticking. (I didn't find them at all!!!) I was thankful he resigned when it happened. Now, I'm positively thrilled he resigned early!

Thanks again for the splendid endgame lesson!

That was asked earlier and partially answered in Post 16:

1. ... Ra1 2. Kh4 Ra2 3. Rb6+ Kg7 4. a6?? Rxh2# (0-1!)

or:

1. ... Ra1 2. Kh4 Ra2 3. Rb6+ Kg7 4. Kh3 (or h3) Rxa5

The question would then be, is there some extension of the second line where white has the advantage? Scarblac already solved the other line (without 2. Kh4) for me.

interesting position

 Nicely done,

it takes over 30 moves to win.. is it worth it? i believe so!

White is up two pawns, one of which is as passed as a pawn can be. There's no way that black can manage a breakthrough, and any sort of a rook trade is 1-0. Even mediocre play from white should be able to promote.

I agree with some of the above. I didn't feel that there was much danger of black winning, and without the rooks, the endgame would be a very easy one for white to win. The QR pawn is certainly passed, and true, white was up another as well. The reason for posting this originally, was that I felt it was a deceptively simple looking endgame. There's more to it than just counting material.

Black was not about to let his rook leave the board voluntarily. Promoting the passed pawn would require technique well beyond "mediocre play," as it is necessary to protect the pawn and the square in front of it in order to advance it. As others have shown through their analyses, this generally requires a timely rook move by white which safely abandons the pawn momentarily by threatening something more significant, allowing white to reposition with the gain of a tempo, after which the pawn may be advanced into protection. (Or, of course, something like yeres's elegant [and not so simple for some of us casual players!] way of protecting the pawn from the front and making it an immediate threat, then forcing the other through.)

Since the game was not an overly long time control, and a fair amount of the time had been used to get to this point, it wouldn't be the easiest position from which to force the point with one's clock ticking. Even without the game pressure, I feel it's an interesting position to study, and I definitely learned something. My thanks to those who demonstrated techniques.

On a side note, I kept from revisiting this thread for a long time, and watched with interest as the "hit" count rose above 1300. With the recent additions, a couple hundred more visits have been added. I hope viewers found (and continue to find) it entertaining, and that some, like me, consider it instructive.

My son, also een 'chess.com' player, has fixed it. I am happy that it is okay now.
