Glad to see Squirrel is still being worked on, have a soft spot for that engine. Was it ever released or still private?

It was a nice tournament and I'm happy that Nightmare was still able to get >50% score. Basically I used the old version of 2013 with lazy-SMP instead of YBW, tuned with LR and a few bugs removed. Of course the AMD-3970X helps too.

The second day of the tournament I had the engine play with a much higher pruning level, it gave weird results, sometimes I saw very strange scores and was afraid that it would play a bad move at some point, luckily this didn't happen. It is never wise to play a tournament with untested things.

It is clear to see that NNUE type engines have the edge, and that old-style engines with handcrafted evaluation fall somewhat behind. I have NNUE on my to-do list, but I want to write it from scratch to get better understanding of what it does and how it works.

Sounds great Joost! It's always a pleasure to see Nightmare play and looking forward to its development.
