Stockfish 17 - Chess324 Top 15 Round-Robin

Post by Modern Times »

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.

Stockfish 17 has replaced Stockfish 16.1 - an approx. Elo gain of +14.

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.
