main villain was a reg. I decided to 3bet here as he was ISOing at basically 100% frequency at this point and the fish were limp folding often so I expected to just pick up the pot here a lot. What do you guys think?
I also was unsure about c-bet sizing on the flop. I figure that this isn't a board that I'm definitely range betting given it's somewhat connected and middling, but one that I still have range advantage on. I felt that 1/3 was too small and something like 2/3 was too big. I struggle with sizing on these kind of boards, especially in 3bet pots. What would you guys recommend?
