#B92 CHESS EXPLORER UPDATE#

If this update still doesn't fix the problem(s) or if there is no update available, the engine might have the number of cores reduced, have the hash size reduced or have the tablebase access disabled - these changes will remain for the rest of the Division. In the case of a serious, play-limiting bug (like crashing or interface communication problems, not including losses on time) not discovered during the pre-Season testing, the engine can be updated once per Division to fix this/these bug/bugs only at the cost of one strike. Cutechess will also adjudicate 6-men or less endgame positions automatically with Syzygy tablebases. On the GUI interface, this rule is shown as 'TCEC win rule' with a number indicating how many plies there are left until it becomes official. It will adjudicate as won for one side if both playing engines have an eval of at least 10.00 pawns (or -10.00 in case of a black win) for 5 consecutive moves, or 10 plies - this rule is in effect as soon as the game starts. On the GUI interface, this rule is shown as 'TCEC draw rule' with a number indicating how many plies there are left until it becomes official. If there is a pawn advance, or a capture of any kind, this special draw rule will reset and start over. However, a game can also be drawn at move 35 or later if the eval from both playing engines are within +0.08 to -0.08 pawns for the last 5 moves, or 10 plies. Check the individual games in the 'Archive page' for info.Ī game can be drawn by the normal 3-fold repetition rule or the 50-move rule. Prior to Season 9, different time controls have been used. If a remote GPU machine disconnects, the decision whether to replay the game or adjudicate will be by the Season administrator. If the TCEC game server locks up at any time during a game (BSOD, freeze etc), that game will be restarted unless the last position was a 6-man or less tablebase position, then it will be manually adjudicated. If an engine loses on time, the result will not be changed or the game replayed. For the Superfinal, the time control is 120 minutes + 15 seconds added per move for the whole game. For Division Premier, the time control is 90 minutes + 10 seconds added per move for the whole game. For Division 1, the time control is 60 minutes + 10 seconds added per move for the whole game. For Division 2, 3 and 4, the time control is 30 minutes + 10 seconds added per move for the whole game.

One game is played at a time - the next one starts automatically.Ĭlassical time control will be used through the season and it is increased as the season progresses. TCEC runs 24/7 until all games have been played. It is a competition between 32 or more engines with ELO 3000+ and is divided into five divisions and a Superfinal. The Top Chess Engine Championship (TCEC) is the premier championship for chess software.
