Coldcalling preflop with big hands (from Ed Miller DVD)

[Niediam]

EP player open raises and you are next to act with AA/KK/QQ/AK. I always thought the very standard play was to 3bet. In Ed's DVD though he suggests that if a raise is likely to knock all but one or fewer of the players out behind you that you should coldcall instead if others are likely to call behind you with an equity disadvantage.

Anybody like this play? Would this apply at all to online games?
