How large do you bet on this turn when playing against 2 opponents? In the moment i was thinking about it, didnt come up with a good idea, so i just potted it, but i dont think its a good sizing.

If im betting flop and turn into 2 people on a board that generally doesnt favor me very much, how do i need to approach this situation theoretically? From my understanding if i dont have many bluffs in my range (as i do have here) i need to be betting smaller, because otherwise my opponents have no incentive to call right?

Can someone clear me up on this?
