$5 MTT - shoving 20-bb with AQ or 88 vs 1 limper

[FeuDuSoir]

Often I will just shove 20BB with AQ or 88 vs a limper.

Because often if I just raise, the limper calls and I will miss the flop (with AQ) or there will be 2 overcards (with 88) and I continuaton bet and they call me and I hate those spots so much, I just shove preflop. [img]/images/graemlins/smirk.gif[/img]

Am i missing much value in with just shoving preflop?
