When that's the case then, IMO, you should 4bet for sure. If your image is one that will get worse hands to shove then the 4bet has to be the +EV play.
Funny thing about this thread is that this same topic has had me thinking a lot recently in MTT's, to the point that I PM'ed Irexes about it to know his opinion. More specifically, I asked him what he thought the best action is when, in an uncontested pot, you raise from the button with a strong hand like QQ or KK and get 3bet from one of the blinds.
The issue around it is, of course, finding the way to get max value from your hand. If you 4bet there is the danger of getting worse hands (99-JJ, AT+) to fold and losing value, but, in some instances, you also could get those same hands to shove.
There is, however, a significant difference because the discussion I had with Rex was in the context of an MTT, and I know this thread refers to cash games.
Although the 2 settings (ring vs MTT) carry, for obvious reasons, different considerations, some of the conclusions are similar.
