This was my first hand at the table. I examined the table for a while before joining because I knew only one player who wasn't SB. SB seemed to be loose PF (as are most of the PLO$2 players ) but after the flop he was quite straightforward. I didn't expect him to fold to my bet on the flop (hardly anyone folds to the $0.04 bet HU on the flop at PLO$2). However, after he called my bet on the turn and the river could complete a flush, I wasn't too confident I had the best hand. What do you think about my bets on the flop or on the turn?

You have bottom 2, so K4/K5 has you beat here, and with no redraws, i don't know if i'm betting the turn, i'd probably bet the flop, then slow down and try and get a showdown

I'd raise preflop here.

I think your line is fine. Your hand is super vulnerable but could be best, and the villain has shown no aggression or signs of having your 2 pair beat. I like betting the turn and checking behind on the river (or folding to a bet if he leads into you most of the time).
