Hi Dieter,
This position was a lot more complicated than I thought and as such I guess it's
a lousy test position. Here's the whole game:
Capablanca - Kostic [C42]
Havana, 1919

6. Rxc5 {1s} Rh3 *

It's not easy, but I think the main line would go like this:
7. h5 Rh4 8. f3 Rh3 9. Rc8+ Ke7 10. Rc7+ Kd6 (Going to the back rank would be
simlilar to the game continuation.) 11. Rxg7 Rxf3 12. Kxh6 Ke5 13. Rb7 b3 14.
Rb5+ Kd4 15. Kg6 Kxc4 16. Rb6 Rh3 17. h6 and the Black king is out of position
for defending the k-side, White wins.

Interesting variations Dieter, the key theme to it all is that White definitely
has the advantage and must slowly exploit it, without allowing Black dangerous
counterplay as in his passed b-pawn becoming threatening or allowing Black to
liquadate down to a drawn R+P ending. The position is very delicate being
another example from book annotations like "and once White penetrates to g6 with
his king the game is as good as over". As you've shown it's not so easy.
All the best,
Jim
