checking behind is better then bet folding.A ton of hands are raising this turn that we have outs against and its a great scare card to semi bluff.
I really doubt many players at 2/4 are sophisticated enough to make a semi-bluff at the pot when an Ace comes on the turn. Against a typical opponent at this level, you'll find out whether your behind or not on the turn by betting.
But how behind?Ax might checkraise the turn but we have 7-9 outs on Ax.I'd be much more inclined to take the free card with our gutshot and 2 pair / trips draws.
Our hand is very vulnerable on this board, I wouldn't mind dumping it if played back at to be honest against most opponents. Sometimes, I may fold the best hand or have odds to call that turn raise, but more often than not if your check/raised your beat here and very often way behind or drawing dead.However on the flip side, if we check and let something like 67, that would suck. First of all, we let them get there for free and they may have folded and given us the pot if we bet the turn, but even if they hadn't folded, we would have gotten in the ideal situation of putting money in the pot with the best of it.As I said before, checking may be a good option against tricky opponent, but against an unknown, it's better to bet in this spot.
