I'm trying to pick it up right here.
Against a better opponent I know that we're beat if we're called, but against him I'm not sure we're getting alot of value.

Should we have checked to induce a bluff since he's so laggy?

* Hands we beat: (I have alot of problems with this one) ATo+,A2-4s,KK-99,T9s,JT (Like I said I've seen him slowplay before, I also know that his PFR is o which is why I include KK-99 but it's such a small sample. Please help me here)

* Hands that beat us: A5+ AA,77,88,78

Turn: ($0.34) 2 (2 players)
Hero bets $0.20, Button calls $0.20

2 is a total blank so I'm still totally confused, not knowing if we're missing value if we check or if we're spewing money since he's not calling with worse.

River: ($0.74) 2 (2 players)
Hero bets $0.40, Button calls $0.40

I guess the only thing that changes here is that we beat 87 now.
-------------
Total pot: $1.54

Results below:
Button had 7, A (two pair, Aces and sevens).
Hero had A, 5 (two pair, Aces and twos).
Outcome: Button won $1.47


I guess this hand is like überstandard, but I don't really know what to think of it. Some thoughts?
