Maybee you are right but I have seen a lot of games with "Colle-structures" where the human slowly can build up a king-attack. Of course his normal d4-lines are (objectively) much better but also sharper and much more riscy against a fast computer. Do you mean Marshall (d5)? It could be very dangerous to play for more then a draw in this variation. I don't think it is a good choice to play normal Ruy-Lopez variations against computers because it is to complicated and often leads to open and complicated positions. I don't know much about the Berlin-defence and if it is the right choice against computers. I have 434 computer-games in this defence in my computer-base out of 94000 games played by computers.
