4bet with QQ, river over bet push all in, hero call/fold?

The river would be a call for sure. You only lose against a J or KK+ and I doubt he would over bet shove this to often and those hands would bet most likely the turn as well. You could consider to make a value bet on the turn I think, because there aren't many hands he would check twice what you lose against.

Yes, i see, turn check is suspicious, i should had to raise. Thanks!

I see no point of playing QQ in a 4bet pot OOP, even against a player that 3bet a lot.
Even if he has a high fold to 4bet stat, I'd consider to bluff 4bet weaker hands and just raise/call QQ type of hands (Qq-Tt? AQs+? AKo+).

I think our range advantage would be enough to compensate playing the hands oop. But I could be completely wrong :-)

OTF and OTT, I think I'd cbet small. Maybe 1/3 of the pot.
That could be tricky, of course, 'cause villain can bluff raise us, but we need to extract value from Ax hands.

Otherwise, what is the point of 4 betting pre with QQ, if you are not willing to be aggressive pos on such dry boards?

Not sure if I'd say that 20/15 is a lag. He looks like a tagish with station propensity.

Anyone with higher stats than 15/13 would be a lag for you? On the FR context, of course.

Anyway, when villain is too aggressive and I'm oop, my tendency is to play stronger ranges and let him hang himself. But, again, I could be wrong.

You right maybe tag, but i pretty sure villain is not a nity player. And out of the position call QQ i guess wrong play. Villain 3bet range is very wide, lot of Ax, Kx and i sure he cbet almost every time in 3bet pot, so from flop to turn come ace or king i had to give up my hand.
