Hi,
villain was unknown and the big turn raise looked like a monster. If villains plays flush draws aggresiv I guess he will do that on the flop.
I block AQ and TT+ will 3-bet preflop. So i give villain 87s,T9s, 88,77,66.
Turn fold ok?
5fcaa7c5 (UTG): $2.36 (118 bb)
Hero (MP): $2.00 (100 bb)
655a428c (CO): $2.00 (100 bb)
c13ecf27 (BU): $2.37 (119 bb)
15168650 (SB): $3.19 (160 bb)
cba6aa3b (BB): $2.05 (103 bb)
Pre-Flop: ($0.03) Hero (Hero) is MP with A♣ A♠
1 fold, Hero (MP) raises to $0.06, 655a428c (CO) calls $0.06, 3 players fold
Flop: ($0.15) 8♦ 7♥ Q♦ (2 players)
Hero (MP) bets $0.10, 655a428c (CO) calls $0.10
Turn: ($0.35) 6♥ (2 players)
Hero (MP) bets $0.26, 655a428c (CO) raises to $0.84, Hero (MP) folds
Total pot: $0.87 (Rake: $0.07)
655a428c (CO) wins $0.80
and 
version, but that are 1 of the few hands you could beat and makes folding resonable. Off course on NL2 villains could over play some hands and that makes folding a over pair really tough.
