No todos los finales de torres concluyen en tablas

por Karsten Müller
26/03/2023 – Lo habitual es que los finales de partidas de torres concluyen en tablas. Al menos normalmente tienen una gran tendencia a las tablas. Esta posición debería ser ganada por las blancas y de hecho lo es, pero Iniyan necesitó trabajar muy duro para demostrarlo. ¿Puede usted hacer lo mismo y dar una prueba convincente de victoria para las blancas?

Of course I have asked Fred to give concrete lines and now I am very curious...

Fred Davies: Dear GM

I had a look at this riddle. I decided the best thing to do was to try and formulate a winning plan based on the respective pawn structures.

1. The first thing to note is that the Black King must stay on blockade against the passed g and h-pawns supported by a Rook. On its own, the Black Rook would be unable to hold back their inexorable march.

2. Black's a7 ands b6 pawns are effectively fixed. If e.g. the a6 pawn moves, they will be picked off by the White King.

3. In some lines, White can force zugzwang based on Black's pawn structure. Therefore, his only trump card is the passed e-pawn. At a propitious moment that could be advanced e.g. where the d6 pawn has been sacrificed/lost.

I conceived of a winning plan where White captures the d6 and e5 pawns - giving up the g and h-pawns. At least one c-pawn must be retained - with the Black King cut off by the White Rook. Eventually the c-pawn is the winning suit - better still - White plays c5 at a propitious moment - thus, the second c-pawn becomes the winning ticket as it is shepherded home by the White King.

If you want some analysis let me know.

Best Wishes
