I don't think so. Pit two top programs against each other in a 100 game match
starting from that position and I believe you'll get at least 99 draws.
In other words, they will misevaluate the position but get the draw anyway.
Here is another example. For at least the last 20 moves, both programs had a
big advantage for the side with the superior material, despite the obvious draw.
Yet a draw was played out in the end.
