Looking at the silly opening move 1...Na6 and the weird play of Rybka 1 in your 1+1 rook odds event, I remembered that early Rybka versions (at least Rybka 1, maybe 2?) had a bug that showed up in lines where the score exceeded 512 cp either way; it would play almost randomly. Probably rook odds is close enough to this line for this bug to cause serious problems. I recall that even amateur players could give Rybka 1 two pieces or queen handicap and win, even though in normal chess it was stronger than the world champion! Anyway I think it is unsuitable for use in handicap tournaments because of this bug. It was corrected at least by version 2.3.2a, probably by 2.2.

Another surprise.

Stockfish without a rook beat Fruit at 15+10 so it seems that the problem is not only with Rybka so I am not sure if against engines knight odd is smaller than rook a1 odd.

Well I've done enough extensive tests to prove that rook odds is clearly a larger handicap than knight odds in general between engines, but it may be that certain engines play better with or without a rook than with or without a knight. Most likely it's just a question of the tiny sample size, but I'm surprised that SF won a single game from Fruit 2.2.1 at rook handicap.
