Any Human Player.. even a Novice can see at a glance this is a Win for White! It helps prove my point! Comps have No intelliegence, no knowledge, no plan, no strategy. All they do is 'evaluate' the position 'on the board' and make the best move found, when it has to move, then the search & evaluation begins again from Ply 1. Don't be too hard on Rybka though, it's not really fair to compare a 'dedicated' Engine against a Top Commercial Program. Of course they do the same thing, work the same way.
