Viridithas 15.0.0 - Chess324 Top 15 Round-Robin

Modern Times · Post by **Modern Times** » Wed Oct 16, 2024 9:50 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.

Time Control: game in 2 minutes plus 1 second increment, 2'+1" on an Intel i7-12700 @ 85w
(runs at approx. 4.3Ghz with concurrency 8)

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.

Viridithas 15.0.0 has replaced Viridithas 14.0.1 - an approx. Elo gain of +35 and jumps from 9th place to 6th place.

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.
