Betting flop is generally good though that flop makes a lot of pair and oesd+ hands that will c/r you and may make you fold the better hand. Once you check the flop, that turn is a fold because there are very few rivers that you can call or value bet. One of the most common issues for PLO players is multi-street play (geometric pot growth is underlying reason why issue exists). Calling on turn in a small pot without a clear river plan is one such example.
Flop check is fine, fold turn. River call is good against some and awful against others. Generally awful without a read, but you are playing on PartyPoker.
