Chess324 Top 15 Round-Robin - Clover 8.0

Modern Times · Post by **Modern Times** » Thu Sep 05, 2024 11:52 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 rather than a ratings list, however I am showing Ordo Elo as well as the tournament scores because they are of value to some people.

Clover 8.0 has replaced Clover 7.1 and remains in 5th place. An approx. Elo gain of +10.

Clarity 7.2.0 at 16th place is pretty much within the error margins of 15th placed Stormphrax 5.0.0, so it stays in the tournament for now.
