Looking quickly at that Rook ending with Gambit Fruit, I have no good knowledge
of Rook endings so I'll just report the computer evals: the evaluation gradually
goes to 0.00 but there where no points where Gambit Fruit saw a real mistake.
I'm not sure how Gambit Fruit sees the draw, probably search? Aha 50 move rule,
that may be it. There seems no real escaping it.
Gambit Fruit thinks 82..Kd2 is a bit better than 82..Kd4 but that is probably an
illusion? Don't know I never got further than the elementary Bishop's endings...
Technically, Rybka did not seem to go wrong in the ending, so the evaluations
are not important. But if you want to study the ending you would rather see
"correct" evalutions, even if the engine only gives 0.00 because of move
repetitions instead of specific endgame knowledge or in this case I suppose
because the 50 move rule can't be crossed without giving away material.
In the middlegame, the position where Gambit Fruit would have chosen another
move was one move later than Gandalf; 28..Be3 instead of 28..Bxf2
