JJ vs super arggo

[ahnuld]

Playing 2-4 on Prima, with a certified maniac at the table. He is 56% flops, 37% raise, but the last 20 hands in a row he has raised 15 to go whenever it gets to him. For some reason, noone is check raising him but me! Anyways, he normally calls the check raise and plays aggressive on flop but will slow down by turn.

I have 650, he has 800. He makes it 15, I raise to 45. Everyone folds and we take the flop heads up.

95 in pot. Flop 7 /images/graemlins/club.gif 9 /images/graemlins/club.gif 4 /images/graemlins/spade.gif He leads 40 into me. I flat call, which I realise is a HUGE mistake. Turn is the 8 /images/graemlins/club.gif 180 in pot, he bets 150. I have the J /images/graemlins/club.gif

Whats the move on the turn? what should I have done on the flop?

ive got him on possible two pair or straight draw and maybe a small made flush, unfortunately you have one pure out with the 10 /images/graemlins/club.gif ... on the turn i think you have to fold or be ready to risk about $300 more for his river bet

i doubt you can win this without improving though
