With MCTS algorithms the error margin is high at the start of the game, and low in the endgame. In a handicap game against a stronger opponent the assumption is that the weaker player will make more mistakes (i.e. has a higher error margin overall). But MCTS programs don't see it that way - their opponent model is the same strength as they are. So they choose a move that gives them 95% (+/- 20%) win (against themselves) instead of the better move that they only gives them a 90% (+/- 20%) win (against themselves). (I.e. I'm saying their error margin in the opening is much greater than the difference in their estimate of move values.)
