I'm an Idiot

Your raise just screams semi-bluff. Either commit yourself or call.

if this guy is gonna call you with something dumb, dont raise... against most, moving in on the turn is good. given the way you played it, you should call allin.

[fisherman112]

you're calling him preflop knowing he gets too attached to hands, this is entirely the wrong opponent to semibluff.
you said yourself you think he'll pay off with a weak hand, call the turn, catch your draw and make him do exactly that.

Preflop call is questionable, but if you had played, flop call was fine. I like a check or your raise here, however, if villian pushes his hands too far, I would be more inclined to call thinking he will pay me off if I hit either of my draws. If I had raised the turn, I most likely would have called the reraise as well or just called his intial bet to see the river pretty cheap hoping I hit and win a big bet on the river. I doubt he would have trips, since you said he had 3-betted a A8 with an A on the board, so that doesn't take any of your outs for the flush, but still possible.

fold preflop
call to the end if you have odd.

You say that vilain is a maniac. Don't try to be aggresive against him with only a draw.
