Chess324 Top 15 Round-Robin - Clover 7.0

Post by Modern Times »

This is an 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, where new versions replace previous versions, and new entrants cause the bottom engine to drop out.

Clover 7.0 has replaced Clover 6.2 and remains at 6th place but much closer to PlentyChess 2.1.0 now.

Nice, thanks for the test :D I actually didn't to any FRC/Chess324 testing so it's nice to see that the expected gains kindof match normal chess gains

Yes I think in these conditions it is around +20 Elo which I think was around about what you were expecting for normal chess at a fast time control.
