Semibluff ok, but turn bet wrong?

EP Limps
MP (T5000) Raises to 120

I'm on the Button with T3000 and have 5[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/spade.gif[/img]. I decide to call the min raise thinking that (a) I have position, and (b) if I hit the flop I may get paid well by the big stack.

SB+BB both fold.
EP calls 60.

Pot=T450

Flop: A[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/club.gif[/img]

So I have an OESD.

EP checks.
MP makes a small bet of 140.

Pot=T590

I decide to raise to 400. I want to try and represent an Ace and hopefully win the pot right now. And I still have my draw to fall back on.

EP fold.
MP calls my raise.

Pot=T1250

Ok, now I'm likely in trouble if I don't hit my draw.

Turn: 2[img]/images/graemlins/club.gif[/img]

MP checks.

Ok, my raise on the flop has given me the free river. Should I take it? Or should I bet again to try and win the pot?

I bet about half the pot.
MP calls.

Pot=~T2500

River is a blank.

MP checks.
I decide to give it up. It looks likely MP will call a bluff at this point.


Alternatively, I guess I could have called the 140 flop bet getting ~4-1. But I'm really trying to play more aggressive poker these days.
