In computer self-play without opening book Capablanca Chess has only about half the draw rate of orthodox Chess (about 16%, vs 32%). These are all games that start well within the draw margin, though. So as play approaches perfection, they should eventually get a 100% draw rate. A large body of opening theory can be viewed as an attempt to play perfectly at least for the first 20 moves, or so, reducing the game phase in which result-changing errors can occur accordingly.
