Actually...
...although everyone's analysis is correct [it is simply a semi-bluff followed by a check raise giving the strength of your hand away], "the move" is quite effective at lower limits. I can't explain how, or why, etc, but I have used it in the past ... and even at the $1/2 tables, it actually works pretty well.
Obviously, you're not going to stack off a world class player, but if you're a low limit NL grinder, it's a weapon that I've certainly used in my arsenal often.
