I’m pretty sure I shot myself in the foot here but I would like to here people’s thoughts on how they play this differently.

Live tournament £45 buy in with £4500 prize pool (£1.4k for 1st)
20/95 remaining 10 places paid. Blinds 1.5/3k 300 ante. Average stack 85k

Ok so I’m dealt Qc Qd in mp+2 9 handed (90k ish stack) it’s folded round to mp+1 who limps in and I raise to 12k. It folds to the button who calls and mp+1 also calls. Mp+1 has limp folded to 3 of my squeezes in recent hands and raised twice pre flop with AK and JJ so when he calls im putting him maybe on a smallpocket pair or AJ/KQ kind of hand. I have no reads on button other than he has around 70k in chips.

Flop: Qh 7c 3d (pot 42kish)

Dream flop for me here but this is where things go tits up. Mp1 checks and I check back hoping the button bets out and I can get some value from my hand. I’m hoping one of them has caught a 7, smaller set or even hit the Q with a KQ sort of hand though that’s unlikely. Also go given the board texture I felt I could give them a free card and hope they improve on the turn. I’m not worried about a turned set of kings or aces as they would have 3bet pre. Button bets 15k anyway and mp1 calls. Check raising here looks very strong and likely gets two folds so I decide to flat (1) and decide to shut it down with a check raise on the turn, hoping to get value off smaller pairs or sets. (2)

Turn comes 5c. (Pot 97k)

Mp1 checks and I check without thinking (3) given that i had already made my mind up to check/raise and expecting button to lead out again. Button checks.

Flop 10c

I’m not liking this card but I figured if the button had turned a flush draw he would continue and try to either get two folds or get value if he hits (4) I’m pretty sure mp1 hasn’t got a hand here as he has played so passive. I make a value bet of 25k (5)hoping to be called by most pairs/sets and button shoves his 40k ish stack. Mp1 folds and I call Button shows KJc for the flush.

So to me this is a combination of a bad beat and me not knowing when to stop slow playing and shut down the hand. I’m aware there are a few spots where I played this badly so I’d like a line check from you guys if possible.

1. Is the check/call here ok or should I always Cbet? Am I right to think check/raising kills my action?
2. Assuming you play the flop as I did, what action do you take on the turn. Check/raising or lead out? Obviously this is card dependent so given the turn was a club, what should I have done?
3. This was pretty terrible from me I think. In retrospect I think the right play here would have been a 2/3 pot bet to shut it down or force drawing hands to fold at least
4. Does this make sense?
5. Is it worth betting here given that I’m crushed if has hit the flush and reshoves? If I check, is it going all in regardless or can I really check fold to his shove?

Thanks in advance for the hopefully constructive criticism. I know I played it pretty bad so I just want to know how I should have played it better on flop/turn really.
