From memory:

.50/1 (6 handed)

PK raises UTG with A-10o. Fold, fold. Button raises. Blinds Fold, I call.

Flop- A - 9 - 2

I check, he bets, I call.

Turn - K

I check, he bets, I call.

River - K

I check, he bets, I call.

Do i try and get away from this hand or do I play it anymore agressively?

I think you should raise or bet somewhere.
Check raising the flop and folding to anymore agression is probably the best bet.
You will very rarely end up folding the best hand, and you get more value from the stuff you beat (which will definitely call down).

Without knowing more about the Button we're missing the context of the situation.

The button might be playing an Ace but he could be betting a pocket pair as well. He has the lead and position so its common for him to make the continuation bets on each street.

I would either go for:

1. Flop check-raise and see if you get 3-bet. But since button has position he may just set call the check-raise and set you up for a bet-raise on the turn. You'll at least save some money by folding then.

2. I like betting out the flop and he will likely pop it. Make the 3-bet and if it gets capped then make the call. If he bets the turn and you don't improve you're probably beat.

Again, if you know more about the player that may change things but you definitely need to know where you stand.

Take the WA/WB line (ie check call down, like you did).

If he has a PP, let him keep dumping money.

A case could be made for donking a safe river, stopping a free showdown. I'm not so sure that this is a safe river.

your check call pisses me off.
i saw layne flack do it once with aces against mike the mouth and it made me want to scream. put in a raise or 2

Fold preflop. Do you really think that your AToff is usually good here with a raise and a 3-bet preflop? Now they have position on you and you're in a mess.

He raised UTG with it, someone 3-bet him, and he called.
"PK" = pokerkid = hero

Gotcha. I don't mind his line, because while he saves a little money when up against aces, he loses money when he gets their KK-99 to fold. However, if they aren't good enough to lay down these pairs I would suggest that you lead/3-bet or check-raise the flop.
