doube check on turn bet

just want to make sure that checking this turn with these stacks/pot is not good, even though there are still 2 others in the pot.

flop lead I took to be a draw or scared PP trying to find out where it is, the fact that two called my flop raise had me a bit worried, but not enough to make me check.

both are pretty unimpressive straightforward seeming players. I haven't really been out of line, though I have been adding in raising over limpers more lately with a wider range from LP, though I don't believe that I had done it much at this table yet.

Zomg check the turn imo. They both called your sizable raise, I don't think they are going anywhere. You've bought yourself a free card, now take it.

i don't think you have any fold equity.

betting is plus ev, but that doesn't mean it isn't a mistake.

check.

Check and hope to hit the flush. I would be super worried about BB unless he is a bad player. Plus both of them only have $40+ left so they are pot-committed with anything that's ahead of you (i.e. any pair).
