The first thing that jumps out at me is I would have bet more than $50 on the turn.
If UTG+1's range includes a straight or the naked A
, this is a great card for you and you need to get as many chips in the middle as possible (UTG+3 being all-in is irrelevant). Something closer to the size of the pot, but at least $120.
By the river, I think I make a crying call hoping to avoid the A
and/or 9
. Then again, your $50 bet on the turn may have been seen as weakness and this may have been UTG+1's attempt at a river bluff using the scare card. I do not see how you can fold that. Too much out there to walk away with the essential third nuts.
