The point is that vasik in the readme wrote the following words (that I mentioned in the post that James replied to): "chess knowledge wins chess games. If it doesn't, it isn't knowledge." I guess that he meant that it increase the result of the engine but if we look at what he said and not in what he meant then his words mean that only drawing games instead of losing games is not knowledge. Note that I do not believe that there is knowledge in evaluation that can help only to draw games instead of losing games because if a program knows by evaluation that some position is a draw it can help it to avoid the draw in case that it has better position and if a program knows by evaluation that some position is a win for one side then it can help it to get it and not choose an alternative that is not clear.
