Chess324 Top 15 Round-Robin - Viridithas 14.0.1

Modern Times · Post by **Modern Times** » Sun Aug 18, 2024 5:21 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.

--- Viridithas 14.0.1 has replaced v 13.0.0 and has jumped from 9th to 8th place with an approx +30 Elo gain ---

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.
