Hii guys
I normally cbet BU vs BB 100% with 1/3 pot size on such a board texture (K62r) since on my level the population doesn’t check raise a lot it is certainly a valid strategy. However, when BB is more tight or an aggressive player against whom I don’t like to play postflop it makes for me more sense to use a polarized strategy (at least I think so…). What do you think about my cbetting strategy?

BU vs BB on K62r with 45-50% sizing (I check back the combos without any bd fd when the hand is marked with a mixed strategy)

I decided to bet around 60% of my hands, should I bet more of my air hands or even check back more of my weak broadway hands where I decided to check only the suited combination back without any bd fd?
Grateful for any advice, thank you
