Using Auto Buttons when Bluffing/Semi-bluffing?

[Two_Slick]

Any players on here make use of the auto-action buttons when bluffing/semi-bluffing? One scenario from game I was just playing:

Hero is KQ off in middle position.

1 limper, hero and blinds call.

Flop is JT4 all different suits. Is checked to limper who bets, hero raises, blinds fold, limper calls.

Turn is blank (7h or something) limper takes a few seconds to act and I auto-select Bet/Raise...

For this scenario I obviously don't make this play if re-raised on the flop and I definitely don't do it all the time -- just on occasion.

Thoughts? Anyone think this can make a bluff/semi-bluff more convincing?
