We do not have so many and they will also be tested against single versions therefore. Probably and depending on votes of testers there might be a separate list for this deep versions. Our thought is that in the near future a lot will have dual machines and more and more engines will come with deep versions, so why not start to test them. Hash indeed is a prob. While Deep Fritz is doing well with more hash, Deep Junior 9.0.0.3 obviously has probs here. We are just discussing this problems and what to do. Best Regards Heinz http://www.husvankempen.de/nunn/
