interesting endgame

[jdart]

This occurred in Olivier Deville's OpenWar tournament, in a game between The Baron 2.2.2 and Alaric 707:

[D] 8/1K6/1P6/5p2/5Pp1/3k4/6R1/1r6 w - -

I think the only move that gives White drawing chances is Ra2, with the idea that Ke4 can be met by Ra4+.

Here White played Kc7 and lost after 78 .. Ke4 79. b7 Kxf4 (after which White had a huge fail low). The problem is, White will Queen first, but Black can give up his Rook and still win. The game continued: 80. Rh2 g3 81. Rh8 g2 82. Rg8 Kf3 83. Rg5 f4 84. b8=Q (after Rxb8 Kxb8 we have this:

[D] 1K6/8/8/6R1/5p2/5k2/6p1/8 b - -

which is a tablebase win for Black).

1.Ra2 seems the only move to draw but threason is white is threatening 2.Ra5 and 3.Kc6. (There's no point with 2.Ke4 Ra4+ Kf3)

1.Ra2 seems the only move to draw but the reason is white is threatening 2.Ra5 and 3.Kc6. (There's no point with 2.Ke4 Ra4+ Kf3)

Agreed, but what I meant was, other White moves allow .. Ke4, winning. After Ra2 Black doesn't have this.

I'd prefere the idea 1...Ke3, what allow 2...g2
