Requiem 0.53 WB#136  (2084+15
−15
)Quote
Author: Severi Salminen (Finland) Released: 2002-09-26Link: RWBC
Issues with this engine: Requiem 0.53 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).
This is the only Requiem version we tested.
