I believe Chess Aurthors are beginning to realize how important it is to allow chess users to have has much flexibility in changing engine parameters as possible. CM9000 for example has about as many engine tweaks as one can give. Shredder and Fritz also have adjustments. We find these three programs advancing in strength over the past few years because of users always finding "that better setting." I believe the Authors to these engines see this and can build a better much stronger engine. Chess Tiger on the other hand is very limited in making adjustments and it shows. This program has falling as one of the strongest in the past year. NO ADJUSTMENTS!!! I believe having hundreds of people playing around with engine parameters and posting them for others to see and test is better than one person testing the engine over and over, even though its its his/her own. Look at how much stronger Rebel has gained by having users play with weights and settings. Ed now can take this info and make adjustments with the code. Watch Deep Sjeng do the same thing. Now there are code adjustments and there are weights and settings adjustments. Dont get me wrong. Code adjustments need to be given to the Author!! My two worthless cents-:)
