Questions.
Is checking the flop bad? I want some action and im not particularly concerned if the gutshot completes. Players are far too tight to be playing such a hand
Turn. I would have raised had i known what opps held but is calling here ok. Im hoping that i can find a good sized value bet on the river rather than scaring my action away here.
Im open to how badly i played this, i tried to keep my action while just not killing it.

The check on the flop is okay, its about as safe as you can get for slowplaying although you may have trouble stacking someone later in the hand. Most importantly you have to raise the turn. The gutshot just completed but now there are hundreds of other draws out and the tables waking up. You are in position and have the power to price the next card, put the money in while your ahead, build a pot before a scare card kills your action or beats you.

You say you don't want to scare away the action which is fine on a safe flop with 2 cards to come, but the turn is the last time you can possibly get action from a draw without losing a big pot. Your also not punishing weaker hands hard enough.

agreed. I think i was worried about giving a free card on the flop which wasnt the error. The error was letting someone else price the turn.
