Oh! I have found the source of my problems: https://cgit.git.savannah.gnu.org/cgit/gnubg.git/commit/play.c?id=bada21ae6315ddc49827ee789a0249d1fabcd2ef
When generating FIBSBoards for the external player, GNU Backgammon will alway set player 0 on turn. This change dates back to 2003 - 23 years ago. So this is why I struggle to have an external player working both as player 0 and player 1. I'll see if I can find a simple way to recreate the bug! (and maybe suggest a patch). -Øystein tir. 24. feb. 2026 kl. 17:44 skrev Guido Flohr <[email protected]>: > > > On 22 Feb 2026, at 15:37, Øystein Schønning-Johansen <[email protected]> > wrote: > > So, has anyone else worked with these two systems, FIBS server and > external player.
