I haven't. I simply never gave the "user" the option to do this. Remember, I am not making this thing as a "custom-made-to-order" program for end users. I am using crafty as I had planned all along, but I decided to distribute the source and executables as a "pay-back" for years of enjoyment in Computer Chess. That said, it is important to note that I didn't "disable the possibility". It was never there in the first place, which is different. I have tried to make crafty behave as I want it to on ICC, and in this case, the behavior could be better. And it is on my list to change. But it wasn't done to prevent user control, it was done to make things totally automatic for me so that I don't forget to do something on ICC and have it screw up. >Ofcourse its very easy for me to let Crafty think he plays a 'human' so he will >resign anyway in comp-comp games if I wants but I dont think thats the right way >to do, is it? > >Best wishes, >Leo.
