You're right, tough spot. Very read dependent.Even though TAG preflop you could still bring this in and bet the flop with a wide range like AKs, AQs, 76s, or overpair. Although normally it takes a better hand to call a raise than make one I think the button can call preflop with sc or gaps like KJs, or an overpair like TT or JJ. His call of the flop bet indicates he's got a piece of the flop, or is willing to represent that he does. I check to the button here and see what happens. If he checks behind we play poker at the river. I check again and call a reasonable. If button bets the turn I think you either have to raise or fold.
