Global Poker $4NL - Not many reads on table except most seem loose passive. Turn was the only confusing part for me.
UTG - $3.86
CO(Hero) $3.64 AdQs
BTN - $9.42

PF: UTG limps $0.04 , hero isos to $0.16, BTN calls UTG calls.
F ($0.54): As5sQh - Hero bets $0.36, CO calls
T: ($1.26): 6s. Hero bets $0.68, BTN raises $1.92. Hero folds

At this point SPR is less than 3 since on the turn I had $3.12 and the pot is $1.26. The turn obviously isn't that great for me obviously but I do block some flushdraws. Villain can't have QsXs. I am not sure if the fold here is correct. Really he only reps a flush draw (I think he would raise 55 on the flop) IMO and I felt tempted to call since I still had a Qs which could potentially beat some of villain's made flushes on the turn, and I could still fill up to a boat on the river. If I had AdQd maybe this would make me lean more towards a fold.

Was this fold too nitty considering how low the SPR was? If we were deeper, would this make us lean more towards a fold?
