For the first Douglas Modern chess final, I decided on a 10-game match between the two contenders, with time control set at 30 minutes plus 15 seconds per move. I was worried that, sans opening books, they would simply play the same games over and over, but it turns out that they’re smarter than that.
There were more draws this round, given that the engines were as equal in strength as I could get, without the neural network ones. I have not succeeded in getting those (eg Lc0, AllieStein, Stoofvlees, etc) to work yet.
Of the ten games, Stockfish won half (as both black and white) and drew the rest. So we declare Stockfish the official champion.
The games in general were longer, some hit the 50 move rule, and there were those annoying shuffle endings as well. Anyway, here’s the numbers and the games.

I’m going to take a break from this now, though may post results on Github or write a paper, depending on how things go with work. Must finish the Giza papers.
