hi

you must 3-bet preflop.

i think i would call sb's 3-bet on the flop, since utg3 folded. then i'd raise the turn on a good card, like the 5 was. and call down from there.

if the read is realiable (70 hands is not much) then he's way overaggressive and you likely still have the best hand a lot of the time.
