Tribeca $.25/.$50 NL, full ring (9-handed).
I get AQ in the BB. MP, who raises a decent amount preflop but is not a maniac, is first in with a smaller-than-normal raise, to 3x. Button calls, and although I hate AQ oop it's only $1 more and I think he may be raising light this time so I call.
Pot $4.75, flop QT3 with 2 clubs. I have the . I decide it's time to try a check-raise instead of my normal lead-out. I check, MP bets $3, button calls $3, and I raise to $10. MP thinks for quite a while before calling. Button folds.
Pot is now $27.75, turn is an offsuit 6. My opponent started out a little bit shortstacked, and has $26 left.
I think for a while. I have obviously over-represented the strength of my hand so far. What I can't decide is whether he took so long to call because he was thinking about folding, or whether he was thinking about re-raising, or what. I only have TPTK, he was the PFR, and I'd feel like a total donk giving him my stack if he had KK or AA (or QQ/TT). He can't have [Kc] or anything similar because I have the .
What could he have called with that I'm beating?
What do I do now? Was the check-raise a terrible play here? If so, why? Should I have CRed stronger?
Help help!!
