This is a big search tune done with chess-tuning-tools and 11 parameters (which is insane!).
The first 130 iterations were done by @TheBlackPlague (thanks again!), with rounds set to 128 and tc of 5+0.05 each iteration was taking about ~80 seconds on a 128thread (limited to 64 threads because of cutechess) machine!
After very promising first results I continued with the tuning for another 60 iterations each taking ~400 seconds with 10 threads. There might be soom room left for further improvements in the future.

A big thanks goes to @kiudee for his amazing tuner, chess-tuning-tools.
