A tight and profitable player 3xed UTG with 14bbs and a loose fish UTG+1 flatted with 49bbs. I 3b AKs expecting to get it in with UTG most every time.  I sized my 3b small, 2.75x, to entice UTG+1 to shove a wider range even though I am never folding.  To my surprise, UTG folded and UTG+1 called. I am not very sure of his range but I expect it to be around: 77-JJ, ATs-AQs, AJo-AQo, KTs+, KJo+, QTs+, J9s+. He could have more pairs and/or suited connectors as well. I do expect almost every player to get it in with QQ+ and AK so I capped his flatting range.

            We whiff the flop and the range I gave UTG+1 smacked the flop so I decided to give up on the hand and continue only on good turns suck as A, K, J, T, and diamonds. The flop checked through and the turn did not improve us. UTG+1 led very small which made me think he has a very weak hand. I decided to peel because I had the odds to hit an A or K against on pair and I thought I would be able bluff scary river. The river brings a four-card straight and UTG+1 checks to us.

            I am looking for advice on how to play this hand from the start. Do you like my 3b sizing or should I size it bigger to avoid situations like this? Do you agree with how I ranged UTG+1(remember he is a fish)? When we get to the flop, what is your plan for the hand? Do you like bet/folding or bet/calling the flop? Should we always raise such a weak bet on the turn? And as played, should I stick with my plan to bluff this river and if so, what sizing is best to get a fold from one pair?
