Myracle GUI

Thank you for the explanation, and sorry that my wording was not clear.

By “dead position,” I meant what the FIDE Laws describe under Article 5.2.2: a position in which neither player can checkmate the opponent’s king by any possible series of legal moves, even though legal moves may still be available. A permanent blockade can produce such a position.

My question arose while considering engine-side recognition of these positions. Your answer clarifies the main point: if Myracle asks the engine for a move and at least one legal move exists, the engine should evaluate the position as 0.0 but still return a legal move. Sending bestmove 0000 would instead be treated as an illegal move, causing the engine to lose the game.

I also understand that Myracle detects trivial material configurations and, when enabled, Syzygy adjudications, but not general dead positions caused by permanent blockades. Therefore, if Myracle does not recognize such a position, the engines must continue supplying legal moves until another rule or adjudication ends the game.

Thank you again for your help.

go to your tournament tab and pause the tournament. then click edit tournament and remove torch first (double-click it) and then crafty

Thanks a lot, that worked.

One more question: Is it possible to combine two different tournaments, play the remaining matches, and then create a single tournament out of them?

no, something like this is not supported, sorry. you'd have to combine the pgn files manually later
