A play that works 99%....if

[PokerEveryDay]

You and one other opponent see the flop and your first to act and have the lead. You bet out (continuous bet) and you get called. The turn comes and you check, now if your opponent also checks then your set. The river comes and now you bet, 99% of the time your opponent will fold. Is there something about this or is just that the guy doesn't have anything? Or, looking at it from your opponents side does this play mean trickery/strength and will get them off a hand?
