how to deal with this turn raise

[joker122]

i cap preflop because i think the 3bet from SB is often for isolation purposes.

i don't have reads as i'm new to the table.

edit- missed BB's raise, my instinct would be to 3bet here but is there anything that we want SB to fold and im not sure if its value. I wonder if BB flopped a set and slowplayed the flop hoping for you to raise?

no way SB is folding AA,KK,QQ or any 2 /images/graemlins/spade.gif's
