You Can't Bluff A Calling Station

I saw this article about Harrington On Hold Em mentioned by Andy Ward on Secrets Of The Amateurs.

Apparently the standard of tournament play has increased as more people are reading Dan's books. Well, perhaps. I'm sure the Two Plus Two guys weren't shy about coming forward with a few quotes for the press on this occasion.

Not that I'm saying anything against the books. However, if people want to call your continuation bet on the flop purely on the basis that Dan says so, that's a recipe for raking a lot of big pots with AA and KK.

Just lay off the gas a little when you miss with AK/AQ.

Or am I missing something?
