Resp 0.19 64-bit JA Nobook WB#88–89  (2402+16
−16
)Quote
Author: Peter Rosendahl (Germany) Released: 2002-06-12Links: WBEC, Jim Ablett's compile
"JA" compile is made by Jim Ablett.
Issues with this engine: Resp 0.19 does not count the opening moves when a GUI opening book is used. This leads to incorrect time allocation and time trouble, therefore Resp is playing without any opening book in this tournament. (Bug details posted at Winboard forum).
This is the only Resp version we tested.
