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.
