    More Details:    • All of the Top engines are AVX2, and tested via theirs default Evalfiles     • As usual, Unique opening book suite used (based on 1113+ openings)  For more fair conditions, each of used opening line repeated as twice    • Plus, for more fair tour conditions, Engine Learning is disabled as well    • Sure where possible: all of engines are played via move overhead 300     • Draw ratio: 87% it's normal..rather bit high, but 3800+ Elo participants    • As usually, all the tournament games available after the end of event..
