Nobody knows whether a perfectly played game of chess is a draw.

We do know that slight differences in search depth and pruning
make a huge difference in computer vs. computer games, and far
less difference in computer vs. human games. That alone is
enough to explain why computer vs. computer matches have fewer
draws.
