QQ overpai conected board, how to play this horrible turn? xD

Pre flop you should have to raise here about 10BB or if you have information villain can not fold pre flop 3beted, you easy 3bet here 12BB. Flop i beted more, because JJ, 1010 or draws you have to protect your hand and get value. River bet i don't understand, you have got showdown hand and if you have not any information villain can bluff lots check-fold the river.

I think you played this hand poorly.
Flop is more a check/call line being OOP. BTN has lots of hands you beat that he will probe (8x,7x,6x, even overcards).
I also think that you should check almost 100% of the time OTT. If it goes check-check, you can bet/fold the river for sure.
If he bets the turn, you have better hands to defend with in a check/call line than QQ (JJ-99, 98s-97s, 87s, 76s-75s, 65s, 54s...). Of course it would depend on his sizing (the bigger the bet the more you should fold big pairs).

I don't know how to play that river when you double barrel and get called.

I'd go bigger preflop
Flop is gonna be a mix (mostly check I'd assume), going for a bet is fine, so is half pot size with a large one you should just check
Turn you just check the card is really good for his range and not many worse hands are going to call

Now just check/fold for sure

I wonder if these spots are a struggle by the way
We can take a look at them tomorrow in database review of a member

- just join in the chat and ask me to run a filter for 3bet Pots OOP
