Right. Looks like white must play Ke2 after black's Rf3+. Then if Kg5 white
plays Rf1 !

Interesting what would have happened with colors reversed. For example Century 3
needs 13:50 on an k6-2 500 before it plays as Ke2 (after black's Rf3+). It likes
Ke4 until the switch to Ke2.

Here's another difficult position for non table base programs(and me too) ...

[D]R7/6k1/P7/8/8/8/6K1/r7 b - - bm Ra5;

According to analysis by Rauzer and Rabinovich, Ra5 draws.
I used to think this was a win for white but stumbled upon this diagram just
today when looking for a similar position.  At least I was in good company as an
old analysis by Tarrasch's claimed a win for white also.

Is anyone getting Crafty to run through Chess Partner 5? If so I am going to put
on my priority list to download Crafty and get the Nalimov endgame table bases.
How big are these bases? Where can I download them?
