I keep hearing this justification to certain plays in plo, such as 3betting a hand like 9887ss sb vs bu, for deception. Yes, I get it is something like, having a hand villain wouldn't expect us to have, but shouldn't it usually be backed by some ev calculation, or like if villain doesn't expect us to have this type of hands in these spots he's likely to be putting a lot of chips in "theoretically speaking" , when we hit. It would be something then like having a lot of implied odds?
