B&M $5/$10 NL Hand...

[Prof. Booty]

I wasn't involved in this hand (my friend was), nor am I a big NLHE player, I was just wondering how you all felt about the way this was played out (by all players).

$200/$700 min/max buy-in NLHE at a local B&M casino - 6 handed

Hero is SB with a stack of about $500-600 (can't really remember exactly how much)
Button has about $400
CO has them both covered (about $700-800)

Folds to CO who limps, button also limps. SB makes it $60 (or $65, forgive my memory) to go with 55, hoping to take it down right there (from what he tells me). BB folds, both limpers call.

Flop comes K 9 5 rainbow.

Hero bets $135 into the ~$200 pot. CO moves all-in for ~$700 (effectively putting both players all-in). Button calls.

Hero?

I am not as interested in results as I am in how each player played the hand (Hero for now, the other 2 when I post results).
