No reads on villains, and small samples so far. Not sure what the best line here is on the flop. Vs sizing XC seems fine, turn merges well with his range and even vs his sizing can't really do much. Is this a slam dunk CBet tho?

Hero (BB): 104.6 BB

I think you played it fine, CB is not making a better hand to fold, also he can just bluff us with worse hands effectively by raising otf, instead I go for XC but Id xf ott as well

You can bet small yourself, can't make a huge mistake by betting small in early streets. It puts his range in an awkward spot if he isn't used to playing vs small sizes and micro limit players isn't usually.

I actually like this, and have been using this lately.

Ac is an important card making the hand closer to cb.
