I would fold preflop. The 9 devalues your hand. If the 9 was a Q your hand might be worth a call. Being suited Jack-high does not add enough value to turn this hand into a call.

On the flop you have 13 out for a straight (four 6s, three 9s, three Ts, and three Js). Making your straight does not guarantee winning high. There are already three low cards out. You are only playing for half the pot. This is a clear fold.
