Depends on how bad your opponents are. If I sit at a table where there are a bunch of garbage calling stations, then i will tighten up. That doesnt mean im not raising when i do play, it means im not trying ot steal the blinds with junk, im not putting c-bets out with no outers, and im limping more often with drawing hands, hoping ot hit a decent flop. For the most part, im still raising when i play, with low pocket pairs i want a big pot so that i can play for stacks if i do trip up, with unpaired high cards im trying to thin the field. But im still playing tight, smart poker. If they are going to call you king high , then why c-bet? If they are playing any two from the blinds, why steal with jack 4 suited?

That being said, you cant stoop down to the level of your opponents. Being non thinking players, you shouldnt be trying to outplay players like this. But that is still no excuse to play badly. Tighten up your preflop range. Bet youre hands hard when you do hit, and watch your stack grow.
