Turned top set on 3 flush board vs fish

Posted 9 years, 5 months ago

Blinds: $0.10/$0.20 (6 Players) BB: $21.50 (Hero)
UTG: $8.00
MP: $24.32
CO: $7.46
BN: $23.65
SB: $26.66

Preflop ($0.30) Hero is BB with A A

4 folds, SB calls $0.10, Hero raises to $0.80, SB calls $0.60

Flop ($1.60) 9 4 K

SB bets $0.60, Hero raises to $2.38, SB calls $1.78

Turn ($6.36) 9 4 K A

SB bets $0.80

So what's our move here?
Villain looks like a passive fish after 118 hands but has also donk bet turn and fold vs raise once before and stabs 50%
