Matant 5.04 WB#145  (2053+17
−17		)Quote
Author: Antoni Szczepanski (Poland) Released: 2007-06-26Link: WBEC
Issues with this engine: Matant 5.04 does not count opening moves as part of the time control when external opening book is used. This leads to incorrect time allocation and time trouble. (See discussion about the same bug in other engines). Because of this bug Matant often loses games on time.
This is the only Matant version we tested.
