Chess324 Top 15 Round-Robin - Clover 7.1

[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, not a ratings list as such.

Clover 7.1 has replaced Clover 7.0, and has jumped from 6th to 5th place with an approx +16 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.

Yes indeed, although the Caissa and Obsidian authors may be keeping a close eye on their rear-view mirrors
