TCEC Season 1 - Stage 1 final lineup and start date

[BB+]

Round 6:

• Rybka-Komodo, 17. d5 seems to cut the board in two, with Black's Q+R in the a8 corner not that useful. Black's Q-side movements are no match for White's K-side actions.
• Vitruvius-Hiarcs, looks as though the White pawn storm created a bunch of threats, with Black choosing to give up a piece. I'm not quite sure why Black played Nh5 on move 10 in the first place, but both sides seemed to like it.
• Gull-Houdini traded down fairly fast, and I would be surprised if either side should lose. Spike-Critter and maybe Hannibal-Chiron similarly didn't show many chances for either side.
• Junior-Shredder was fairly interesting, I'm not sure whether White chose the best technical endgame in which to convert, though the attack did get a bit overextended.
• Stockfish-Quazar was a bit puzzling to me with some of Black's moves (the rook foray leading to the exchange loss, and then Stockfish converting to R+pawns vs NN endgame), I don't know if it Quazar was getting out-searched, or had a different view in evaluation.

A minor suggestion, at the Crosstable on the bottom of the live page, would it possible to colour-code the games that are yet to be played? The "*" at the end of something like "0003:b*" does not always immediately stand out [whereas additionally making an alternate colour would highlight it], and makes it harder to parse which engines are yet to play this round.

Hi BB+,

Well I would suggest to use the Schedule for reference over who has played or is yet to play.
Of course your suggestion could be possible, I would have to do it with Javascript then since the Crosstable is automatically generated by ChessGUI. I have other priorities at the moment, but I will keep it in mind for later.

Anyway, after almost 1 month, here are the final standings of Stage 1 after Round 7. The top 16 moves on to Stage 2a and 2b, while the bottom 16 is out of TCEC for this Season.

Here's a list of ratings spit out by my programme. With 7 games per engine, the error margins are large.
The observed White Elo edge was only 8 Elo. I am not sure what the ERROR column here really means, it seems as
though I take some variance measure of the actual results versus the expected from the ratings.
