I feel like I missed a bunch of value yesterday. Gonna have to try and figure out some way to work on improving on that.

UTG was 25/20 with a 78% fold to 3bet, BTN was 15/15 but with a 13% 3bet preflop

Preflop: I'm pretty lost here. At the table I heard a booming voice telling me not to flat 3bets OOP, but I feel like if I 4bet I'm basically putting myself up against {KK+, AK}. I think button's range for 3betting here is: {88+, AJs+, AQo+, KQs}. I think it's gotta be a tighter range than 13% when he's 3betting an UTG open, but I really don't know what somebody's range for that looks like, so the above could be way off.
I call, as does UTG, I think with the range: {77-QQ, AQs+, AKo}.

Flop: Here I check, expecting BTN to cbet, and I'm intending on calling it. However it checks through. I'm now less inclined to put overpairs and sets in his range, as the board's not exactly dry against two players.

Turn: Here I bet out, expecting to get called by UTG's {88, 99, TT, AQcc+} - I'm chucking 99 in there 'cause since nobody bet the flop he might consider it good for one street. and by BTN's {99, AJcc+, KQcc}. I've got like 48% equity against the two of them, so it's a fine value bet.

River: UTG calls my turn bet, BTN folds, and river bricks. If I value bet I think I'm getting called by sets, jacks and queens, which I tie with (6 combos of JJ, 3 combos each of TT, 88). However if I check then he probably fires his missed clubs, queens, jacks and sets, so I think check/call is the winner here.
