With this action on this board, I think no matter what we do, we look super strong, so I'm just trying to get my money in early, against the widest range possible. I think if we flat, we give too many opportunities for villain to get scared, or bad cards to peel off and hurt our action.
At 3/5 spread, the cap is 4 bets, correct? I think a near minclick 4-bet to ~$560-580 makes a lot of sense here. We should always get action from straights, combo draws, and sets. IMO, we should try to get some action from 2pair hands as well by using a small size that may look like us trying to isolate with an overpair. It also leaves us with around $600 to bet later in the hand.
in low stakes games you can raise the amount that accomplishes your goals, which will vary by holdings, because so few players are correlating your sizings with your hand strength.
