Reads on the SB are somewhat important as well.

In general I think it will take him more than 8 hands (even if you've 3-bet him twice) to adjust to the point that 4-bet bluffing is good, and if you do feel you've come to that point then he's probably not folding that many better hands than AT anyway. You're hoping for him to fold AJ and 22-88?

If this was button vs blinds then I could see both shoving and calling as reasonable options if the dynamics are right, this being UTG vs BB and with a caller in between, I think a shove is pretty much suicide.
