BU is middlestack, I´d 3-bet pf to get initiative, he´d likely call with worse hands and you don´t mind even if he folds
lead out/3-bet is fine on teh flop, but raise to 6$, then you can shove at any turn card
shoving turn imo is better than c/c, since you´re not folding river, getting too good odds to call.
