This is not necessarily true -- it depends on how your search works. In my case, ripping out knowledge will definitely make my engine much slower at solving tactical test suites. I use the evaluation function to choose the null move reduction factor, to decide which moves should be extended, reduced or pruned, and to decide which moves should be included in the qsearch. With a simpler evaluation function, I would have to search much bigger trees in order to see the same tactics. In other words, I agree that faster is always better in tactical positions. But very often, knowledge is the easiest way to be fast. Tord
