What is the November 2019 strongest engine

 

I was doubtful seeing the last Sedat Canbaz tournament which placed Brainfish with contempt 40 (??) much higher than the same program with its standard settings... I've commissioned an engine tournament to Deiby L. on an i9-9900k machine (hence quite accurate) and I was right: the program with contempt set as 40 slightly differs than the one with the standard settings... Plus, BrainLearn 5.2 X reached the second place..

The numbers goes to Sedat Canbaz, as he made 500 games per engine instead of 100, but I'm doubtful on the way he makes the tournament: Deiby's one lasted 2.5 days and we "only" have 100 games for each engine, while in Sedat Canbaz tournament he makes around 300 games in just one day or little more...

I've chosen to use all the original engines and not the ones compiled by me, except Stockfish Polyglot of course, so that I can't be contested to use modified versions.

I have set contempt 24 because I've noticed in my test that with it set as 0 there were too many draws.
