In realtime, the graphs are OK, but for those who don't match TCEC 24 hours a day, eyeballing a graph from a decisive game in the post-mortem can often not reveal too much.
Junior had another nice win against Sjeng, after White was preferred as much as 1.00 by Sjeng (move 26).
But then, just as I came in, Rybka had jumped fairly rapidly from 0.00 to 2.96 in a rook ending against Junior (which was almost drawn previously due to lots of near-0.00 scores and shuffling). The first move where Rybka had a non-0.00 score was 72. Rxh5, after which Junior originally thought Black was better. The scores were both 0.00 from move 50 to 63, but then Junior favoured Black a bit after the a4 push, but moving the King up so as to support the a-pawn backfired in the end.
I went to bed before the Rybka-Junior game ended and I checked the position with a couple of engines (Shredder, and Rybka) and they were adamant that it was a draw. I love Junior but I have seen it blow many a win and/or draw because of some icky endgame play.
