A little set action

[gol4pro]

100NL at full tilt, stacks are 115$. Villian is LAGish but not psycho. He is aggressive with high cards after a PFR (generally Cbets pot on flop).

Villian raises to 3.5$ UTG, hero calls UTG+1 with 4 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/club.gif[/img]

pot 8$
flop 6 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/spade.gif[/img]
-- villian checks, hero bets 6$, villian calls
-- He thought for a while before checking, so I think he's trying to get cute with AA/KK.

pot 20$
turn 8 [img]/images/graemlins/heart.gif[/img]
-- villian checks, hero bets 15$, villian raises to 55$, hero pushes

standard?

i dont understand the reasons for your reasoning lol
he took a while to call on the flop, thus he has AA or KK?
