Afaik this problem only occurs when you use odd truncation and even
plies or vice versa (according to a statement by Daniel Murphy). I did a
lot of truncated rollouts of positions and few of them also with 2ply
full but didn't experience any substantial "odds" besides those where
truncated _and_ full rollouts showed that 2ply eval was wrong.
