Same opponent as this hand. I played the hand several days ago so I don't remember everything, but it was relatively early on in the match (which was only 72 hands before villain left). He was playing loose and aggressive, almost too much so as he never folded to my tight 3bet range, and only folded 30% of his hands OOP vs my tight button open of 69%.

Standard 3bet for me.

Still need help figuring out which flops to cbet and which to check back. But since he is defending so wide I really want to be betting here. Something interesting to note is out of our 5 cbet instances in 3bet pots he hasn't folded to a single one. I presume he is floating with a wide range of hands here. How should I combat this?

I think the way to combat his wide 3bet defend range preflop and the fact that he never folds to my flop cbet in 3bet pots I should be barrelling lots of turns, though I feel like with just a gutshot here and the Q pairing the board is this a good spot to barrel?

Also, I need help getting the correct thought process for "what's a good card to barrel?" etc. in terms of my range vs his range.
