Another thing I would improve - this window is weak. You should be able to open the engine and save it.

There are a few things I would improve.

board size - so that it can be reduced or enlarged
number the board fields
make a "New Game" and not a "Play Game"

Sorry, I entered the score 2-0 by mistake. It should be 1-1. I'll correct it soon.

You did it very nicely. I have another question because I'm interested in it. Is it possible to change the engine name? Let me give you an example of what I mean. I have an engine Ares Al 1.91 and I would like to change the name to Ares Al 1.91 x 64. Is it possible?

For the option I marked in red - I would give an option for the number of moves.

Gijsbert, thank you for posting some of the details about how you interact with Codex. Very helpful.

See the game below: on move 61, Dragon had an already clearly winning 6-against-2 position, but chose to simplify by sacrificing two pieces, reaching a winning ...

I'm sorry but I have to change the date of round 5. Round 5 will take place on 05-06-2026 at 9:00 CET.

At least it should be possible to play two tournaments - Swiss tournament, round-robin. Give many more options in the GUI, those I wrote about earlier.

Add Swiss tournament.

Hi Krzysztof,

These are part of the engine configuration and is not replicated in the tournament settings (and would not apply to DXP engines anyway). The first tournamnt completed succesfully:

I'm sorry, it's still poorly done. Everything must be run from the ...

Hi Krzysztof,

The next version will have a tournament option. This would allow you to automatically run a tournament between engines that support the hub protocol:

I can see from the picture that it's done poorly. The following items are missing:
