I have been testing various engines against each other playing Douglas Modern chess and have now got to the point where I have identified some very strong engines, some strong, and the rest. To give the better ones a shot at being champion, I’ve started a series of round-robin heats, with four engines at a time. After the 12 games, the best three will advance to the next round. The format of the final(s) is still to be decided.
The groups I’m using are:
I expect the final four to probably be Stockfish, Xiphos, and two of Laser, FIre, or Ethereal.
