Bodo 0.2b WB#127  (2137+15
−15		)Quote
Author: Joel Veness (Australia) Released: 2003-09-23Links: Homepage, RWBC
Issues with this engine: Bodo 0.2b does not count the opening moves when a GUI opening book is used. This leads to incorrect time allocation and time trouble. (Same bug in other engines discussed at Winboard forum). Occasionally Bodo 0.2b is losing on time.
This is the only Bodo version we tested.
