Honestly it probably matters very little what you do here. The BB will call pretty rarely whether you raise or not, and only slightly more if you don't raise, at least I think so. Meanwhile there is always the slight glimmer of a chance that you get the button to fold preflop.

These two factors probably cancel out. When this is the case I usually go for the more straightforward play, which is to just move allin preflop.
