£.05/.10 home game, 5 handed. We're all pretty decent players (we'd make money at 50NL if any of us had the bankroll) apart from one fish who isn't involved in the hand.

Me: £14
ABC: £10

I'm on the button and ABC is in MP. I've been playing with ABC for a couple of years. He's a total ABC nit who can sometimes fall in love with broadways and stack off.. He's pretty much like the 25NL TAGs on Stars - obvious lines with generally strong hands. He's aggressive preflop and postflop when he's got the goods, but rarely blufs.

I've been playing LAG for the past 90 minutes having lost an 80/20 and losing £10, and I've been accumulating chips slowly, as the people I play with don't seem to be really up for seeing turns without the goods. I've tightened up my game in the past 20 minutes though, having had to show T6o at a showdown. (Before that, all the money I made was pure stealing)

It's limped around to me, and I call on the button with :Ah:. I call rather than raise because we have a donk who likes to see a flop with any 2 to my right, and two TAGs to my left who love implied odds, and therefore I didn't want a fat swollen pot with a reverse implied odds hand. (ABC is between the TAGs and the donk)
The SB folds, and the BB checks.

Flop (4 players) (£0.45)

:Ac:

ABC bets out .40, and I call, due to the fact that he could've easily limped a stronger Ace.

Turn (2 players) (£1.25)

:Kc:

ABC checks. I strongly doubt he has the flush, as he's too ABC to even bet a flushdraw off the flop, he'd always check-call here. I check behind, despite the fact that I should've repped the flush.

River (2 players) (£1.25)



ABC checks. I now beat all Aces apart from AK and A2. I bet out £1.20, send out a false "I'm bluffing" tell, and ABC raises to £4. He doesn't give away his usual "Big Hand" tell of finding something interesting on the wall to look at, he just puts on a "Phil Hellmuth Covering His Mouth" pose.

What's my move?
