your opening should be here 5bb at least.
flop he c/r and he is 30/15 so he is opening TT+, that leaves sets on flop , w/o reads he plays like this PP/straight draws/bluffs its a deff fold,you will get him someother time with another hand.
so b/f flop and watch him other hands.
supose he does limp any PP including TT+/stove sets and TT+ in his range and its still a fold.
