Re: On-line engine blitz tourney September

Nine rounds is supposed to be enough for up to 128 players. We could consider using the MacMahon system instead of normal Swiss, however. (I would have to program this in mamer, but that seems rather trivial.) The idea here is that you start the players not with zero points, but with a number of po...

Re: static evals from list of FENs?

Yeah, that's always an option (writing it yourself), but figured it might already exist.

static evals from list of FENs?

Is there a way to feed Stockfish (or any engine) a list/file of FENs and get back its static evaluations, perhaps via one of the GUIs?

broadcasting engine tournaments

Are there any guides/tutorials on the various methods for broadcasting engine tournaments? It seems there are quite a few ways. For example: 1) TCEC uses a likely customized version of cutechess-cli with pgn4web 2) Graham uses Tom's Live Chess Viewer plus dyndns.org 3) Clemens Keck uses some sort of...

Re: transposition tables and three-fold repetition

I'm referring to the move in the TT entry, which hasn't been made yet. But, if we just accept it as gospel and return, then it might have been a repetition. OK, I see. But it seems always wrong to take a TT cut in the root, as the root basically requests an infinite depth, only limited by time. So ...

Re: transposition tables and three-fold repetition

Not if it's ply 0. Wouldn't the game have already ended in a draw, when you havea repeat at ply 0? I'm referring to the move in the TT entry, which hasn't been made yet. But, if we just accept it as gospel and return, then it might have been a repetition. Right, so this suggests a move from the TT ...

Re: transposition tables and three-fold repetition

I have the repetition check at the top of search when ply > 0, so the move has been made in the calling search. Then a TT probe can never be a repetition, as you would already have returned with a draw score before doing the probe if it was. Not if it's ply 0. You lost me. Suppose you are in the br...

Re: transposition tables and three-fold repetition

Usually one checks all moves to see if they lead to repetitions, before making them. And usually the TT is only probed after making them. I have the repetition check at the top of search when ply > 0, so the move has been made in the calling search. The TT check follows with beta and exact matches ...

transposition tables and three-fold repetition

Is there a technique to avoid falling into repetition draws when using the values from a transposition table? I've observed my engine doing this on several occasions now. I'm thinking an exact or beta cutoff move of sufficient depth might have to first pass the repetition test before it can be used ...
