Preflop I tried experimenting with looser calls oop. I think this call preflop is not really necessary but vs 2,5x should be ok if BB isn't squeezing much (which he probably isn't).

Ok so the Flop is a clear check/call imo because check/raise would be overplaying my hand and leading is not good because I expect the average player to bet this board quite frequently with a wide range of hands.

On the turn we get a Gutshot and there is some point in leading now to get Value out of his middlepairs that he may check back.
Would you have led Turn?

Ok so he bets small on the Turn... actually when I think about it now I should have check/raise the turn vs this small sizing because it looks like I'm way ahead vs this sizing from an exploitive kind of view.

Ok on the River Lead should be quite standard imo because I give him the chance to make a herocall with some garbage hand.
