a tremendously interesting endgame. The pieces are in this position: White King a7 and two rooks on a1 and b1. Black King on g3 and two pawns on g2 and h2. White to move and win! if no one gets it, I'll post answer.

Here's my try:

1. Kb7! Kf2

There is nothing better, black must try to queen a pawn or die a quiet death

2. Rb2+ Kf3
3. Ra3+ Ke4

The black King is trying to approach the rooks. Also losing is the attempt to run to the other side: 3...Kf5 4.Ra5+ Kg6 5.Rb6+ Kh7 6.Ra7! g1=Q 7.Ka8+ Qg7 (7...Kh8 8.Rb8+ is the same) 8.Rxg7+ Kxg7 9.Rb1 with 10.Rh1 and 11.Rxh2

4. Rb4+ Kd5
5. Ra5+ Kd6

Black cannot play Kc6 - which is the reason for white's 1st move

6. Rb6+ Kd7
7. Ra7!

And white threatens 8.Ka8+ followed by 9.Rb8#, black has no defense

I am doing this without a board, hope I am not making a fool of myself ...

Somehow, I don't see anything particularly difficult about this ending :) Any number of moves should win, the simplest being 1. Kb6 Kf2 2. Ra2+ Kf3 3. Ra3+ Ke4 (3... Kf2 4. Rb2+ Kg1 5. Ra1#) 4. Raa1 and so on, just bringing the king up to support the rooks. I can't see anything wrong with this :)

i was thinking.... 1. Ra3+, Kf4 2. Ra4+, Ke3 3. Ra3+, Kd2 4. Ra1, Ke2 5. Rh1, Kf2 6. RxP, g1/Q 7. RxP, KxP 8. Rh7 or whatever

Hey! I didn't say it was hard! Only interesting. I had a hard time finding the concept for a while though.
