Problematic turn decision NL25z

Posted 6 years, 1 month ago

Blinds: $0.10/$0.25 (6 Players) BN: $45.58
SB: $26.60 (Hero)
BB: $28.26
UTG: $15.31
MP: $26.68
CO: $61.51

Preflop ($0.35) Hero is SB with 9 A

2 folds, CO raises to $0.75, BN folds, Hero raises to $2.50, BB folds, CO calls $1.75

Flop ($5.25) 9 2 7

Hero bets $1.65, CO calls $1.65

Having vulnerable pair and not having spades I preferd to bet for protecion and win the pot right now, could size up.

Turn ($8.55) 9 2 7 K

Hero checks, CO bets $4.09, Hero folds

I have no idea how to play this spots in 3 bet pots OOP, ih hes bluffing wouldn't he fire a river?
