Not sure on any street

[DaveB]

Party $100, first orbit. I have Ad5d in the cutoff. MP1 limps and I limp. SB raises to $3, BB calls, MP1 calls, I call. Flop is Ah, 2d, Kc ($12). Checked to me and I check. Turn is 3d. SB bets $8 and it's folded to me. I like my hand but I'm suspicious and I just call? River is 3s. SB bets $12. Call this?

All comments welcome, I am still trying to learn NL.

I would fold the river. You called to hit your flush and/or 5. I don't think you are ahead often enough here.

You should have led out on the flop.
Just to know where you stand with your hand.
Maybe the SB has a king and was not sure or even QQ-1010.
He could be trapping, but you have to know if your hand is any good.
If there is significant resistance, be prepared to let your hand go.
Betting is getting information.

You split with any Ax besides A3, AK. I call river, and maybe raise turn.
