2-5 PLO. I just got moved to main game and first hand I see villain stacked for 500 by aces full on a draw heavy board. I cover in both hands. Villain rebus for 500. Did not see his hand and no reads. Unknown to each other. Hand 1 is 2 hands after. Villain limps after another. I open QJJT with three diamonds to 25 in late position. Blinds and the limpers call. Flop is Q87 rainbow with a diamond. Checked to me, I bet 90 and only villain calls. Turn is Kh, second heart. Villain checks and so do I. River is the 9h. Villain instantly jams for exactly pot. Less than a second. Call or fold? Bet turn? Hand 2 is an hour later. Villain took a bad beat to a turned 2 outer in the interim and bought in for 1,000. This is soon after. Several limp and villain pots on the button to 30. He was mostly loose passive. I call in BB with KK93sscc and only UTG calls. Flop is AsKh9s. Check, check, villain bets 50 and only I call. Thoughts? Turn is 9d. I check, villain, quickly bets 150, I think for a bit and call. River is 4h. I check intending to call. Thoughts?
