As a 3better I felt like having advantage with this flop, but still it was quite wet, so decided to c-bet 75% of the pot, to prevent Villain draws - I think that within his range, there is only one combo beating me (KQ) as QQ/KK would be 4bet, while 33 is rather fold for him.
Shall I bet more to make him his calling non profitable, or was my bet size fine? Was he fine to call considering he had 12 outs (flush draw + gutter)?

I might have checked river, but I guess he would bet anyway - [Td] was a good card to make a bluff at the river, so my bet was to prevent him potentially bluffing and making me wonder if I shall call with my bluff catcher [Kd].
I knew he was drawing, but considering that [Td] was a good card only for gutter, I felt like this was a good decision to go all-in OTR.
