Hi,

It turns out I can leverage the (credits spent on the :lol:) previous version by having the new version consult it read-only. The new engine registration dialog box works much better, as it captures stdout and the parameters, you can edit the parameters, (re)launch the engine if it errors out ...

Hi Krzysztof,

For DXP engines you should be able to reconfigure the DXP ID in the 'Engines...' dialog-box: double click on the DXP ID and change the name. The ID of hub engines will be overwritten by the id= that the hub engine reports, I will make the overwrite configurable ('gui-do-not-change-hub ...

Hi,

Joost suggested to have the option to play multiple games in parallel. The change Codex proposed would have worked but I was a little bit concerned about the massive refactor (and associated credits). As I wanted to do this exercise again anyway I now started a new project with the already ...

Hi Krzysztof,

Thank you for your feedback and option has been added:

Hi,

Version 1.7 has been released. It fixes a lot of (small) bugs and stability issues also on Windows (DXP message processing, engine proces management etc.). This version completed a 1 minute per engine round-robin tournament between six engines (2x Ares in DXP server mode, GWD in hub mode, GWD ...

Hi,

@all programmers whose engine supports DXP mode only: currently the GUI will launch your executable locally so can pickup stdout. If you write your PV to stdout also in 'Hub mode' using info=, the GUI will pick that up and show the PV in the GUI, score-history will be shown and the evaluation ...

Hi Ed,

I forgot to mention that for Moby Dam you have to set 'gui-send-starting-position' to 'false'. If 'false' the position after the last non-reversible move will be sent which is what Moby Dam expects.

Hi Ed,

That issue has been fixed in version 1.6, but meanwhile I also found a couple of stability issues on Windows (synchronization issues, processes not always being cleaned up). Version 1.7 with a lot of fixes and Swiss tournament support coming up:

2026-06-02 23_42_45-NVIDIA GeForce Overlay ...

Hi Krzysztof,

I will explore that option. As a temporary workaround I could also add manual pairing, so you could add the pairing for the next round to the pairing table with result unknown. If you then hit 'Start' the next round will be automatically played.

Hi,

I have published version 1.6.

It shows the PV in a (browsable) mini-board. The mini-board can be popped out.
It also shows score-history.
It supports DXP engines for game play. When registering an engine you can configure it for Hub or DXP mode (or both, GWD supports both). You can use {ip ...

Hi,

It should not be too hard adding database support. The first full DXP-only tournament is running now. Hub vs DXP was easy, but DXP vs DXP was much harder. You got the feeling that 'we' were patching patches with patches. 'We' got it working, but I thought it was flaky. If you then ask to review ...

Hi,

First hybrid match between GWD in hub mode and GWD in DXP mode is running!

Hi,

I am running Codex locally but I did not expect it to search my entire drive if needed:

The site is not reachable from this sandbox (www.mesander.nl does not resolve here), so I can’t pull the page directly. I’ll search the repo/local files for DXP notes first, then implement from the known ...

Hi,

DXP support provides editing of the .ini file (if found):

Hi,

DXP support is in the works:
