NL50 Is this too weak?

I'll go you one better (but I wouldn't call it "weak"). I check the flop here. With that many people in the pot and being in the worst possible position, I'm not thrilled about TP and jack kicker. I like my hand, but don't love it. So I check, and if an early position bets remotely decent, I muck. If the button bets, I might call or raise just depending. And obviously if anyone bets and then a raise, I fold too. But I don't mind checking here and then folding to his UTG+2 bet.

Oh yeah, good fold. I think it's a pretty clear fold. If you don't fold it, it's going to cost you a lot of money when he bets the turn and possibly the river too.
