New engine releases 2026 H2

[Graham Banks]

Incredible news!!!
Nice to see this Winboard engine again!!

Dorky is now UCI.

[Elorejano]

If the primary protocol is the correct one (WinBoard), there is no issue with attaching the secondary protocol (UCI).

Gumble, a toy engine that I retouched two years ago but never announced (I believe).

I had fixed a small compilation error with recent GCC, fixed an error in the program (regarding FEN string splitting) and made the program recognize/ignore the movestogo parameter (instead of stopping).

Now I can include the program in my tournaments with Cutechess-cli.
