Villain is good reg.
Took a very straightforward play on the flop but I am thinking about better alternatives:
-check back? I shouldn't be too afraid that I am giving outs he should not have draws in his range. Are hands like K♠Q♠,9 T in his range? I am currently not expecting them. So, is it better to check back and try to get some value on turn/river?
-if I bet I think that it should be no more than 3-4$, so I can make 3 tiny tiny bets and expect him to call sometimes with second pair type hands. Villain is not going to call a bet like mine because he knows that he pot commits himself.
It's practically a min-raise. 
I would do it at least 2,5x.
