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.

Lizard 10.5 has replaced Lizard 10.4 and comes in at 10th place. As a result, Rebel 16.3 has dropped out.
