It's not 50%.
I'll just say that certain hands are profitable opens and are not profitable continues vs players with very tight ranges that play decently postflop where you wont realize anywhere near 100% of your preflop hot/cold equity, this isn't six years ago where players are 3betting and pot/calling all textures where you have massive implied odds.
I am quite content with what my stats are when I look at certain filters in HEM. In before "but you have at least 33% equity and are getting 2:1 so you have to call no matter what."
What I said was specifically about OP who said he is an inexperienced PLO player and who is likely up against a player who has played a few million hands. Villain is 3betting in a spot where his range is such that it is going to crush OP on quite a lot of textures for stacks and OP will get little value on the boards he smashes besides low trips. I am assuming that OP will miss at least some value bets and bluff opportunities that would make this a somewhat clear call vs most players in a reg vs reg scenario. In practice vs OP Villains R is going to be near 100% if not > 100% some % of the time so yes when you factor in the average pot size postflop and hand vs range realized equities, OP is likely going to be losing more than the 3.5bb he opened for preflop by calling.
bombonca you literally play 21/11 preflop, please don't pretend like you are actually winning money at online poker in 2017, especially not at midstakes+. Great analysis though, you are a postflop virtuoso and contribute greatly to all strategy threads. The extra 40bb in preflop stacks is going to change preflop ranges a bit, it should shift villains 3betting range a bit more towards the playability side than raw equity side which is going to hurt your hand for at least a few extra %s points when the broadway card on this texture is offsuit and villain starts off betting.
