"Material exchange" (why can't you call it material-only search or something?) is not the only way to find mates or draws. In fact, you don't need to know a damn thing about material to find mates or draws. That's my point. As soon as you start evaluating material, why wouldn't you also evaluate e.g. doubled pawns at the same time? -Tom
