Rebel 16 is the next step in the cooperation between Ed Schröder (Rebel) and Chris Whittington (Chess System Tal).
Chris Whittington - author of Chess System Tal.
1. Rebel 16 uses the code base of Chess System Tal but comes with its own (much improved) network evaluation. 2. Rebel 16 will be the last version. 3. Now that our work is fully exchangeable (engine and network) Ed will fully devote his time on improving Chess System Tal.
Technical, much to say, best to follow this thread in our forum.
