First results (analysis time 100ms) looked promising 48.3% against the ProDeo book, 49.4% (analysis time 1000ms), now trying 2000ms but I think I am wasting my time looking at the moves it sometimes produces. Was hoping for a bug that could be fixed but looking at the responses that's unlikely.
And so I did, in search for the engine that can play the opening best. I created an opening set from 80,000+ games between (human) players of 2600+ elo for the first 4 moves resulting in 2836 epd positions and ran them with Ferdy's tool MEA creating a sorted list. So far I tested 26 engines and there are quite some surprises.

#1. While Lc0 tops note that this is the slow CPU version and that 1 sec scores better than 5 secs
#2. That Rodent III is another surprise.
#3. That there isn't much difference between SF5 and SF10.
#4. Komodo 10 at 5 secs is almost equal to ProDeo 2.6
I am looking for candidates like Rodent.
