Hand played in a $2.20 SCOOP phase 1 on pokerstars
I'm trying to become a less nitty player and find more bluff spots. Usually if my hand misses by the river I'll give up on the hand, so I'd like to add more bluffs in my game for balance.
I decided to flat pre with 89 suited, as UTG is already opening quite a tight range, and I wanted to keep it as wide as possible.
Obviously the flop is great, so I decide to check-raise in a high-equity spot.
The turn is pretty awful as UTG has all the aces in his range when he opens, and all the aces when he calls my raise on the flop. I decide to check back the turn in order to see a free river card, where I can either shove for value or shove on decent bluff cards.
The river is the queen of diamonds, which I decide to jam. I thought I could credibly rep KJ which might check turn to induce value on the river, or perhaps a queen...

Any tips would be much appreciated
