I am no expert, but bitboards might have more over-head while at the same time they simplify evaluation of the position, which may save you time in evaluating. Although I don't fully understand it, I am told the bitboards can also help in move ordering by looking at captures first, and the improved move ordering reduces the number of positions looked at. My idea of a chess algorithm was not to use bitboards because they do not provide me with all the information that I want. Instead I was going to keep track of a great deal of information each time a piece moved - this approach might be slow but might also help my evalution, move ordering, and pruning. I can't say that it will work, because it might be months before I can put these ideas into practice. But I have started on the user interface. John Coffey
