Chess324 Top 15 Round-Robin - Motor 0.7.0

Modern Times · Post by **Modern Times** » Wed Aug 14, 2024 7:19 am

This is my ongoing Top15 round-robin tournament of free engines only, using Stefah Pohl's unbalanced 3-move book Chess324_xxl_big_+090_+119.pgn played reversed sides per pairing. New versions replace previous versions, and new entrants cause the bottom engine to drop out. It is a revolving tournament, not a ratings list as such.

Motor has entered the tournament for the first time, Motor 0.7.0 coming in at 11th place. Ordinarily this would cause the bottom engine to drop out, in this case Clarity 7.2.0, however 15th and 16th are within the margin of error, so it stays for now.
