Hand from $600 Foxwoods Poker Classic event

[jbird]

It's in the second hour, second level (50/100). I have about 4700 or so, about the starting stack -- I've raised a few hands and taken them down on the flop, and had to fold a few times to aggression when I missed the flop, but nothing big either way. Villain has just over 2000 or so, and he lost half of his stack about 30 minutes ago where he called flop and turn and bluffed river on a K27J7 board (KJ won he mucked). But since that hand I haven't seen him involved in any pots.

I'm OTB, villains SB. MP limps, I make it 400, villain shoves for 2250 or something, limper folds.
