I don't think the depth here matters. It depends on whether one program
thinks it is behind or not, as to whether it is going to see the draw. One
side can force the draw. If a program thinks that side is ahead, then it will
think it best to avoid the draw, and it won't see it ever.
I try to fix things that I believe are costing me games. I don't see this
happening often enough to offset the depth it gets in non-checking lines which
helps it see more non-checking things.
