5-5NL exremely deep short handed

[shag]

Hero has ~3100 behind, villain has about the same. Hero is SB with A [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]. 4 handed. Villain is extremely tricky LAG. Very smart. This is at the bike.

Villain opens for 25, Button folds Hero calls BB folds
Flop (55)

Hero bets 30, villain raises to 100, hero calls. I really suspect an A here for some reason.
