i'm in the 10 straddle UTG and there's a bunch of limps, someone minraises (LOL), i call with Kh9s8s5s, we see a flop five ways

flop (105) comes 3s6d7s. BB checks, i check, V1 checks, V2 pots from CO, V3 flats on button, BB folds, I call, V1 calls.

V1 is a mediocre reg who oscillates between borderline competent and spazzy LAG. can definitely be sticky with quite marginal holdings in PLO. he tends to play a little better when he has over 200bb like he does now
V2 is a fish who has 45 when he does this 1000% of the time
V3 is a super gambly reg who is stuck. he knows i am solid in PLO

turn (525) 8d

checks to V2 who insta pots it again. he is still potting all combos of 45 here because he's a fishy NL player who doesn't really understand PLO hand values and is stuck and just wants to get it in. i guess he can have 459 or exactly 459T but he doesn't need it to pot here.

V3 thinks for quite a while before shoving for a little more, which tells me he probably has a mediocre draw like gutter + NFD or bottom 2 + FD, or maybe 45 + FD that was waiting to see what happened on turn. V3 is a pretty good hand reader, he probably has made the same read on V2 that i described above, but he just can't help himself from gambling in big pots. he is not tanking with a big draw here, he would never get away from something like set + FD or similar, and he almost never has T9 because he is re-potting the big wrap on the flop, we block, and he's folding most combos of naked T9 on the flop.

anyway. maybe these reads seem ultra specific but i know these players (particularly v3) very well, so sharing my entire thought process in the moment. after all that, hero ...?
