UTG: $100 (100 bb)
MP: $100 (100 bb)
CO: $126.35 (126.4 bb)  27/23/55
Hero (BTN): $148.07 (148.1 bb)
SB: $147.99 (148 bb)
BB: $102 (102 bb)

Preflop: Hero is BTN with TcQs, 2 folds, CO raises to $2.50, Hero raises to $7, 2 folds, CO calls $4.50

It is not the greatest 3bet, I am pretty much dominated by his calling range, but he can have some speculative hands, which i have more eq against.

Flop: ($15.50) 4h Th Ts (2 players)CO checks, Hero bets $7.75, CO calls $7.75

When he calls he can have imo 44-JJ, ATs, AhJh, AhQh, 9Ts, TJs, maybe QTs(you can argue with me) I dont think he raises anything here.

Turn: ($31) 5h (2 players)CO checks, Hero checks

I don't think i can get 3 street value(push river) anymore. My plan here is to potcontroll with chback and river vbet.

River: ($31) As (2 players)CO checks, Hero bets $15.50, CO raises to $111.60 and is all-in, Hero $117,82  ?

This is the Wtf part of it.
What do you think he can have here?
