Which GUI supports the following ?

[Modern Times]

A round-robin tournament of say 15 engines
Each engine plays every other engine using a pgn of 100 opening positions, played reversed sides (so 200 games per pairing)
Must support concurrency

I'm a bit stumped on this one. I don't know any GUI that can do it. Last time I did something like this I ran each match individually which was very cumbersome.

WinBoard / XBoard, of course. It seems a pretty elementary task.

CuteChess should be able to do this.

I don't see how, I've tried both it and Banksia.

CuteChess should be able to do this.

It seems to have all the options.

For Tournament:
Set Tournament Type = round robin
Set Rounds = Whatever you want
Set Games per encounter = 2
Set Play Each Opening = 2 times

For Opening Suite:
Set PGN file = your_file.pgn
Set required opening depth = whatever you want
Set Opening Order = sequential

And in the settings, there's an option to run games concurrently.

Yes, but it then works through the pgn sequentially from one opponent to the next, not sequentially per opponent. I'm simply running individual matches to achieve that result. Slower, but for a one-off tournament not so bad I guess.

So what do you actually want, exactly? The settings I gave above should, as far as I can see, pick the first opening line in the PGN, then play two games between the first two opponents using that line, and then picks the next line for the next two opponents. Do you want an entire round played with only that first line, for black and then white, and then an entire round with the next line, and so on? I don't think CuteChess can do that. I don't even know for sure how useful it would be.

Personally I use a large opening book created from grandmaster games since 1900, and have CuteChess pick an opening line for a game, play it for 4 moves per side and then leave the engines to their game.

However, I can imagine that, getting into the 3600+ territory, you need to go and do special things to avoid 100% draws.

The whole point of using a set of predefined openings is to let all pairings play the same openings. This gives the most accurate comparison between the engines, eliminating variance due to opening choice. Besides, using each opening only in a single pairing would require you to have 120 times as many lines, in a round robin of 16.

It souns like a bug in CuteChess.

WinBoard can even force the same lines in all pairings when you otherwise randomly selects from the GUI book, by forcing the same random seed for all games in the same round.

Yes HG, exactly right. It may not be a bug in Cutechess, rather something they didn't anticipate, same with Banksia. Sounds like Winboard is the only GUI with concurrency that supports this.
