I don't evaluate it very high. The program is not obviously weaker if I double it, but it plays a different game and I can see that some other features just get swamped. I think mobility should be done if there's a reasonably inexpensive way to do it, but evaluating it highly is a mistake. Better mobility is just a transient feature of a position. It means nothing if you have weaknesses that are being piled upon, and then it will soon disappear anyway. Amir
