Hero (CO): 239.72 BB

SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has Kc Kh
fold, Hero raises to 3 BB, BTN calls 3 BB, SB raises to 13 BB, fold, Hero calls 10 BB, fold

Flop : (30 BB, 2 players) Jc 7c 7s
SB checks, Hero bets 30 BB, SB raises to 90 BB, fold

SB is unknown,seems like a solid TAG reg.plays aggressively,but I haven't seen him out of the line.
I think I should check back the flop,and even if I want to bet the flop,definitely not pot it.
when he check rasie this board,I think his range is really narrow,AAKKQQ,maybe JJ,the only bluff I think is AcQc and Tc9c.
any thoughts?
