Subject: Two Rook Endgame Test Positions [Baron-Arasan]

Author: Dieter Buerssner

This is from yesterdays ICC tourney. I think, especially without TBs, the
positions might be rather hard.

[D] 8/1R6/8/7P/2k3P1/1p4K1/8/7r w - - 8 97

Here Baron played Rb8, allowing a draw. Rb6 wins (I think, everything else
draws).

After Rb8:

1R6/8/8/7P/2k3P1/1p4K1/8/7r b - - 9 97

Now Arasan played Rg1+, which is losing. Kc3 draws (everything else loses).
After Rg1+ the game continued 98.Kf4 Kc3 99.g5 b2 100.Rxb2!? Kxb2 and the two
pawns win against the rook.

Does any engine without TBs find Rb6 in the first pos with convincing score? And
in the second pos, does any engine without TBs see, that Kc3 is really much
better than alternative moves? The testpositions are not really good, because
the moves can be found without "understanding" the pos.

Regards,
Dieter
