In my opinion, this is a pure implementation issue and in most cases doesn't make good sense. Lets say you wanted separate evaluation functions for closed and open positions. But are closed and open positions that different? The same basic piece values still apply, so why would you replicate the code for that? A rook on the 7th rank is still good, regardless of it being a closed or open position so why would you replicate the code for that? Etc etc. Of course, some things should get higher bonuses in open positions (development perhaps) but that is easily handled by some simple logic. Peter > >Russell
