Here is a possible position that I suspect that 1500 players can beat most programs in both sides. They even do not need to know about the weaknesses of computers so I take back the assumption that the 1500 player knows something about computers. They do not need to predict the moves that are made by the computer. One bad move by the computer is enough to lose a won postion.
