Checking in the dark

I was watching the WSOP main event and thought I saw Howard Lederer check in the dark during a hand (I forget the circumstances). I know I saw Phil Hellmuth do it at least twice during the main event also. They sat at tables full of amateurs . Given that ESPN shows only a fraction of the hands played by top players, I wonder if Lederer and Hellmuth checked in the dark more frequently than what I saw.

During Hellmuth's commentary for CardPlayer magazine's live coverage of the main event final table, he briefly mentioned inducing bluffs from amateurs. This was after Mike Matusow induced a bluff from Steve Dannenmann, but Dannenman spiked a jack with AJ to beat Matusow's pocket tens, if I remember correctly.

Lederer was overheard discussing the amateur players and their propensity to put all their chips at stake on any hand. All of this raises a question: are pro players trying to induce big bluffs from amateurs with automatic in the dark checks, and is this going to become more prevalent in tournament poker where pros play amateurs?

Checking in the dark is something that, as an online player, I never see because of the lack of such a function in the software. I suppose you could say I'm in the dark when it comes to checking in the dark.
