People say raise more PRE, maybe you could but I don't mind 3x..but people still call 4x etc anyway that's fine.
However when you get donk3minbetted you have to now try and put a range of villians hands and how he's been playing but flatting here I think in general is WRONG espically considering if you call, button is likely to call because of pot odds
. You either need to be 4betting if he's a loose donkey and be happy getting it in or just fold because you now have a sitation if an ace comes or a jack like in your case.
When he donk min bets the flop, I'm happy to raise like you did but the problem now with not 4betting and letting a 3 way pot here once you raise, you have to remember button is still in the hand and you're now committed to calling his shove and have to call it off but the in this spot, it isn't ideal. He's in most cases shoving a queen or strong draw which you now have to call.
Either just save the hassel, 4bet shove if he's a loose donk but it's horrid to be in this spot and 3betting the flop, to then have the button shove on you.
