A6s - Defend from SB - Bluff River?

This is NL2 and I wouldn't go for a bluff on the flop with only a backdoor draw against a unknown. I would just call to keep the pot small and her-evaluete the turn. Now you build the pot with in mind you need to hit hard to win the hand and is always tough to bluff on NL2.

3bet preflop could be a good option. i don't mind calling as much vs a 2bb raise, but vs a 2.5bb-3bb open raise i will very rarely flatcall in the SB.

don't XR this hand, your backdoor straight draw is not good so you mostly have Ace blocker and backdoor flush potential.

bet the Turn larger when you hit the flush draw

pairing rivers are bad - it reduces the number of value combos you can rep so you should slow down.
