QQ out of the bb $55, extracting value

[Maulik]

my thoughts during this hand, if I raise, I'm OOP and if I check I'll be able to extract chips by disguising this hand. 2 limpers will not make it too dangerous to play this hand on the flop. I elect to check/call the flop. On the turn, I'm thinking a mini-raise may be good, and a block bet on the river regardless.

on the river when the scare card hits, it seems as though I've been drawing and hit so its unlikely i'll be re-raised.
