that you will find yourself playing against mediocre LAGs/maniacs? And that while these players are where you bread and butter comes from, crazy hands come with the territory?
Obviously i could've approached it different ways, but how?

No hand history. Something is screwy with the computer receiving the downloads, however i wrote some of the information and remember the rest.

Heads up with villain. 6 -max table had petered out.
Like i said, villain seemed to be a mediocre lag, possibly even a maniac. Had a short stack that was fluctuating. Seemed to bet out alot, bet out of position, but not take down pots, give up facing resistance, and lose some pots at showdown. I was multitabling so couldn't get a more specific read than this.

Stacks (give or take some cents):

Hero: $238
Villain: $81

Blinds: .50/1.00
Villian has button.

Hero is dealt Ad Jd.

Hero completes.
Villain raises to $2.
Hero calls.

(I know, I know. I've been employing couterplay strategy recently when dealing with maniacs/terrible LAGs. It seems to be working nicely, but is this taking it to the extreme?)

Flop: As 2h 8d
Pot: 4$

Hero checks. Villain bets $2, Hero raises to $5, Villain calls.

(I'm ahead here, right? Villain seemed the type to preflop push or significantly raise up AQ or better. )

Turn: Kh
Pot: $18

Hero bets 9$, Villain calls.

(Bet more, or check raise again seem much better. This bet was read-dependant on villain, however, as villain had shown to make or call any crazy bet, but bow out against further resistance.)

River: 10c
Pot: $35

Hero checks, Villain bets $20, Hero ???

(To be honest, this river scared me. I couldn't put villain on a range. Thought about A10, i was guessing a weaker ace. Maybe JQ, chasing. Though both of would seem to warrant a higher preflop raise. Villain was preflop min-raising much, and not winning those pots. There was action on three tables at this point, and i believe in hindsight that this would should garner the most attention.)

The play?
