Of course this hand is haunting me because of the results, so now I'm questioning my decision-making... And I still feel new to PLO... so enlighten me all experienced PLO wizards!
5/5 PLO nine-handed, deep stacks (I was one of the shorter stacks with around $1400) - some guys had $3000+ There are some good players, some wealthy not-so-great players. Nobody lacks balls though (except maybe me...).
Button straddles to $15. SB folds, BB makes it $50, UTG calls, I call (UTG+1) with AQQ4 (A4hh), a couple more calls, CO raises pot to $370 or something (CO is a good, thinking player, I put him on a strong value range when he does this - he's quite deep). Button straddle calls (he's deep as hell), as does BB (he only has like $500 left after calling - old guy, not very good). Then, UTG (player directly to my right) goes all-in for like $475 total.
What's my correct play and thought process here? My stack was around $1400. Please help.
