getting beat up

[mike l.]

ok i have Js9s in the bb 3 handed live 20-40 3am game. sb strong pro decent short player openraises, i 3 bet, he calls.

the flop is A73 two spades. he checks, i bet, he checkraises, i 3 bet, he 4 bets. i call.

the turn is 5h. he bets, i call.

the river is a T. he checks, i check. he has 87o. i lose.

5 bet the flop, wait till the turn to show aggression? raise the turn? what? nothing? i lose no matter what?
