Le TCEC stage 1b est toujours en cours, vous trouverez le tableau des résultats ici.
Stockfish y est naturellement et largement en tête.
Le moteur le plus faible,  Nebula 2 continue de faire le spectacle : avec un  ELO de seulement 2097, il a battu Jazz (2371) et a égalisé avec Tornado (2809).

A noter la partie folle entre Tornado et Exchess avec 207 coups qui se finit par une nulle sur la règle des 50 coups.

Sur TCEC, il y a eu quelques indélicatesses concernant les classements des modules...

Pour Nebula 2 par exemple son élo est de 2616 basé sur 508 parties (avec un time control différent mais tout de même...).

The TCEC Season System - Season 6

As soon as a Stage starts, it will run 24/7 until all games have been played. One game is played at a time - the next one starts automatically. There will be a short break between the Stages, to make sure everything is ok with the TCEC game server and to prepare for the next Stage.

Stage 1
Stage 1 is divided into 3 groups which consists of 12 engines each. Each group format is a single round robin. The top 5 from each group and the best number 6 will move on to Stage 2, while the rest are out of TCEC for the current Season.

Stage 2
Stage 2 consists of the 16 engines that qualified from Stage 1. It is also a single round robin. The top 8 move on to Stage 3 while the rest are out of TCEC for the current Season.

Stage 3
Stage 3 consists of the 8 engines that qualified from Stage 2. The format for Stage 3 is a double round robin so that each engine will play both sides of the same opening against each other. The top 4 will move on to Stage 4 while the rest are out of TCEC for the current Season.

Stage 4
Stage 4 consists of the 4 engines that qualified from Stage 3. It is a hexadeca round robin and the openings are chosen randomly per pair so that each engine will play both sides of the same opening against each other. The top 2 will qualify to play the Superfinal, while the other engines are out of TCEC for the current Season.

Superfinal
After Stage 4 has finished, the top 2 engines will meet in a Superfinal of 64 games. This match is played with 32 different openings so that each engine plays both black and white of the same position. The match will be presented with opening 1 used in games 1 and 2, then opening 2 used in games 3 and 4 etc. If the match is theoretically won for one side before game 64, the match will still continue until all 64 games have been played. In the case of a drawn match there will be a rapid match of 16 games with a time control of 25' + 10". In case it is still tied there will be a Blitz match of 8 games with a time control of 3" + 2'. When the Superfinal is over, the current Season ends.

The TCEC Grand Champion
The winner of the Superfinal will be crowned the TCEC Grand Champion and will keep this title until there is a winner in the next Superfinal. There is no automatic qualification for the reigning Grand Champion, it will have to go all the way through the next Season for it to be able to defend the title.


Engine Specific Configuration
UCI engines are supported and Xboard (Winboard) engines will use the Wb2Uci adapter which has no impact on performance. To identify an engine running with the Wb2Uci adapter you can click the gears next to the engine logo during a game. This info will be saved for the archive, but does not work for Season 5 or older games.

Compiles
Many engines come with different .exe files. 64-bit .exes are always preferred over 32-bit. Also, compiles that support SSE 4.2, AVC or similar instruction sets are preferred.

Large Pages
Some engines can utilize a function in Windows called large pages, that gives a speed boost. However, after a while the memory in the computer will be fragmented, so that one engine might receive large pages and the opponent won't, which would be unfair. Therefore, this has been disabled. Large pages are often useful when you are running infinite analysis on a position.

Number of Cores / Threads
Each engine can use up to all 16 cores of the processors, if this is supported. Some engines have a prefix like "deep", but this has been omitted from the engine name to make it shorter. When watching a game you can see the number of cores that are in use for the engines currently playing by clicking the gears next to the engine logo.

Split Depth
The split depth parameter can be adjusted, with advice from each of the engine programmers. Basically it defines the minimum depth for work to be split between cores / threads. If no instructions are given from the programmer, the default value will be used.

Main Hash Size
Each engine is allowed to use up to 16384 MB of hash. Not all engines supports this much hash, so the maximum for that engine will be used in this case, typically 1024 MB or 2048 MB. When watching a game you can see the size of the hash that is in use for the engines currently playing by clicking the gears next to the engine logo.

Minor Hash Sizes
Some engines have an option to configure the size of other hash tables, often called pawn hash or evaluation hash. The combined, total limit for hash types like these is 2048 MB.

Own Opening Book
All opening books shipped with the engines are disabled.

Endgame Tablebases
6-men Syzygy, 5-men Nalimov, 5-men Gaviota (cp2), 5-men Scorpio bitbases and 5-men Robbobases (Totalbases + Triplebases) are available depending on which each specific engine can use. For some engines specifying more than one type is possible, but here only one is allowed. Robbobases also have Z pieces. They are all hosted on a very fast dual Samsung SSD Raid 0 setup with a rough read performance of 1 GB / second. When watching a game you can see the type of the tablebases (if any) that is in use for the engines currently playing by clicking the gears next to the engine logo.

Tablebase Cache
Each engine is allowed to use up to 2048 MB of tablebase cache. Not all engines supports this amount, so the maximum for that engine will be used in that case, typically 256 MB.

Ponder / Permanent Brain
Basically this means that the engines can think during their opponents turn. It is not allowed so it has been disabled. This might change in a future Season of TCEC.

Contempt / Draw Score
Some engines have a setting that can adjust their own view of the positions throughout a game to avoid draws. This setting is not changed from the default unless it is a request from the programmer.

Other Settings
Any configurable option not described above, are not adjusted in any way, except that "keep hash tables" or similar is usually enabled.

On frise le ridicule dans cette dernière partie de Tornado 5 vs Stockfish 180214 : nulle en 221 coups !!!   

J'avoue qu'à suivre...ce fut...chiant   Je ne parle même pas des évaluations loufoques des deux moteurs en direct !!!

Pour les plus courageux
