Nothing wrong with the check at all IMO. People talk about building a big pot but if you bet out I think most of the time villain is folding - you need to give him a chance to take a stab or at least catch up on the turn.
I'd now be betting around 25k on the turn and hope the Q has helped his hand in some way.
Why is villain folding most of the time when you bet on the flop? You have no info on Villain other than that he has been building a very nice chipstack. Unless he is Mr Lucky Luck from Lucksville he is probably one of the few other players that is not scared to play in this tourney and therefore won't fold like a cheap suit everytime someone bets into him. You can always give Villain here room to hang himself by leading out on the flop.
I'd expect him to fold to any bet because of the kind of hand I put him on and the kind of hand I think he's putting me on. I suppose there's a chance he plays back with 88 or 99 but with no real draws out there apart from 89 the chances are he missed completely. If he flopped a set you're getting his chips however the hand plays out.
As for betting on the turn...I don't mind a bet on the turn (in fact I advocated it) but not because "I hope it has helped him in some way" that's just not right. There are but a few hands that the Q will have helped that he gets his chips in with (AQ and QQ really being the only ones) if you lead out here he is more than likely to fold anything worse..(maybe get a flat call out of him when he holds KQ...in which case he probably is Lucky Luckbox from Lucksville..or when he holds the old J9 K10) as he knows you should have something better than just a shitty queen here...so;.
Its a tough pot to get anything out of whatever way you look at it. I know its grasping at straws a little but IMO there's a better chance he has a Q in his hand than any kind of hand that was helped by that flop.
You're not hoping that the Queen "helped his hand in some way"..the queen is a card YOU represent when you bet out, not one you hope HE HAS. You're hoping he already has a hand which is not afraid of the queen..and if he has a hand like that he already would have given you action on the flop..so there is no reason not to bet out on the flop for that reason.
You've lost me a little there mate. If you're representing the Q you're hoping he has KK+ in which case you would have got him to play back on the flop anyway. The whole point of checking the flop was to either let him take a stab or give him a free card to improve.
