The governing truth for poker is that closely protected hands are usually strong. Sometimes, you can even draw a correlation between the amount of protection and the exact strength of the hand. In the video sequence, the player picks up a full house and makes certain it is secure. However, be cautious using this tell, because some players guard all hands. A few will even use a carefully guarded hand as a ploy to make you think that their weak hand is awesome. That's rare, though, because most players realize that the manner in which a hand is guarded is not something most opponents observe.

Assume you're sitting two seats to the right of this player. You wouldn't have seen that he has aces-full, but you'd know he holds something pretty good. You should elect not to open the pot with marginal hands. If this player opens, you should pass with all borderline hands. If you hold an extremely strong hand yourself (say, a straight flush) in jacks-or-better-to-open, you might elect to check rather than open, knowing this player will open for you.
