Hero ?

What are you trying to achieve by 4betting your queens? I think your are folding worse and getting called by QQ, KK, AK and shoved by AA. You are also utg which means you rep a tighter range and so if you 4bet you are polarizing your range to AA and KK. I assume villain thinks this way too but given his stack he might be a fish and call lighter with suited broadways or JJ. In usual cases, his range shoukd be pretty capped. Otf you are either very behind or slightly ahead. In any case since you already invested so much i think u should cbet to about 70-75% to fold his whatever worse like lower pps but i dont think in looking to play post with a lower pp to a K high wet board.

Ups posted sme thing twice, mb

Don't 4bet pre and just check this Flop, expect to get to showdown a reasonable amount when you are ahead.

+1

4-bet is fine vs. small 3-bet from a less than full stacked random. Check and make a decision, but QQ is now the bottom of your range, pretty much.

This obviously isn't true.

Pre is ok can be a call too.
C/f flop. JJ AK KQ go there and we block AQ and most likely he dosnt play that pre flop like this

oh it is 25nl my bad, its a little wider than that, you are right

25nl or not, it can't be true that we're polarised to AA/KK when we're actually holding QQ.
