Live 3/5NL: pair+gutshot

[HoldEmKillah]

both MP and CO are donkeys (clearly). Button is a good, tight and aggressive player. He knows what he's doing and also knows that I am good but play very lag and am capable of making big moves with draws, air or the nuts.

MP ($35)
CO ($41)
Button (~$450)
HERO in SB (covers) dealt 4 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/spade.gif[/img]

MP limps, CO raises to $15, BUTTON calls, HERO calls, MP raises all in, CO calls $20, BUTTON calls $20, HERO calls $20.

FLOP ($140, dry side pot, 1 player all in) 2 [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/heart.gif[/img]

HERO checks, CO goes all in, BUTTON calls $16, HERO checkraises to $150. BUTTON immediately goes all in for ~$250 more.

I think for awhile and call.

I put him on 2 big hearts. I don't think he'd play a set or any kind of overpair this way.

Thoughts?
