This is the first time I have viewed a TCEC game (Junior vs Sjeng). This is awesome Martin!
I have no idea how this could be improved upon, at least in regards to viewing the games.
You deserve all of the attention that TCEC is getting.

Thanks Adam, it's appreciated!

Unfortunately there was a hardware problem making Naum - Spark stop
so I have decided to manually adjudicate that game as a draw.

Also, this problem might be the cause of the SF crash yesterday, so
I have resumed SF - Critter from the last position.

The hardware issues should be resolved now, hopefully there won't be
any more trouble.

Best,
Martin

Junior is often said to be the most "stylistic" engine out there.

Kc5 {<br> +99.81/21 0.2 Black resigns} 1-0Both sides thought they were up by a 1/3 of a pawn or more around move 25, then Junior made the exchange sac, and won.

However, not all Junior wins are always that interesting. For instance, its Round 14 win over Houdini in the recent ChessWar XVI was a rather boring shuffling game with QRR and pawns for each side, until suddenly White's pieces were all in the right places, and there was a combo via the g-file.

[Uly]

Junior is often said to be the most "stylistic" engine out there.

From the TCEC participants, sure, but my money for style is on Thinker (that is so user-unfriendly the style becomes almost irrelevant...)

[Martin Thoresen]

A minor update to the TCEC site has been made.

1: One separate live page with only the current live game (the LIVE link in the menu).
2: The other stage pages will contain all finished games, and they will be linked in color to the LIVE link.
3: A small timer has been added since the last move was made.
4: The crosstable will now update automatically, you can also click "Update" to force it to update.

This should make it easier for people with a low-bandwidth internet connection to follow the live games.

PS: Uly, I agree with your sentiments about Thinker.

Martin, TCEC keeps getting better and better. I wasn't convinced that a Swiss system would be as interesting as the league as there are already so many Swiss tourneys around but I think it's a good format. Keep up the good work and thank you!

A minor update to the TCEC site has been made.

There's also an evaluation graph now. My only comment is that in games that end up decisive, the scaling is such that it is hard to make out any fine detail in the 0.00-1.00 range (say).
