Hey, I am wondering what the consensus is about playing hands like 77-99 UTG and UTG+1 at 2NL and 5NL, particularly in 6max. I hate opening (I will typically open in this position to around 4x the BB) these hands in these positions unless the table is super nitty, because they are so borderline and I find I am often being called by loose players in position with hands like mid suited connectors, J9s+, Q10+, K10o etc.
When I look at my equity against a typical calling range of some of these players (something like): {22+,A2s+,K8s+,Q9s+,J8s+,T8s+,98s,87s,76s,A5o+,KTo +,QTo+,JTo}, equilab gives me 57% equity. That said, I am out of position and I find these hands pretty challenging to play postflop unless I flop a set, the flop is something like 2s3c7h, or if the villain never continues to a cbet.

Should I tighten up? Do I limp in? I have no idea!
