I will keep you posted. > >- Ed Schroder - Ed, If it turns out you are right about this, it will be a great opportunity for us to see first hand how important this feature is to Mchess. However I would point out that the other programs (assuming they are learners) still have an advantage since they will now be "educated" when they re-play Mchess, but Mchess will have to start from scratch. I'm guessing this will not affect things very much since they will be facing a new Mchess and have to re-learn themselves, but it's likely to have some affect. I hope you can make this as fair as possible by re-initializing the learning feature on Mchess opponents. But this might influence other games too with other opponents. Can you comment on these issues since I am not sure how you deal with them? If it turns out that you always re-initialize the learners before it plays each opponent then my concerns are a moot point (not an issue.) - Don
