Villain is more on the tight side (23/16). His 4betting range is heavily leaned towards AA but i guess he´s good enough to have some premium rundowns too. 

Flop: I guess villain should checkraise quite a lot of his getin hands in order to avoid awkward turn situations and because we can bluffbet quite a lot on this board. So i´m never really happy to stackoff blindly with bottom2 pair. On the other hand, our hands value will mostly heavily decrease on most turns, so i prefer to bet. (Is my thinking ok?)

If i bet, and get jammed its most probably a fold. Thus, how should i choose my betsize? Imo 60-64 gives me enough room to bet/fold as well as being able jamming the river if called from a SPR point of view.
