As many have said, it"s very player dependent this spot and the villain was calling down alot of his chips light with not much of a redraw. I felt this was a spot to double up as he rarely had much. And we were playing alot of pots together (6 max) and there was other metagame going on as we kept making each other fold. Yeah I realise 4 over cards are inconsequential in PLO but had a feeling that if I hit one I should be good as he was seen to doo this with medium pairs (77,88,99,1010) on a paired 5 hi board.
At the lower levels there is alot of limping but as others said, you can have 4 limpers to a pot. But if you open raise you still get the same number calling. I find it"s the pot 3 bet that thins the field
You open with aces in plo with no flush draw then get 4 callers your in a world of pain unless you flop top set or get lucky and hit trips with your danglers! However, 3 limpers or a raise then 2 callers an you 3 bet the field will thin alot then
