[ QUOTE ]
If player A stands, however, this signifies to player B that player A's hand is greater, and that player B should now hit. To have an edge for this move as a bluff, player A must have a hand greater than .50, because it is very likely to induce Player B to hit.

Not necessarily. If I have .49 and B has .53, and I know B will hit if I stay, then staying is clearly the correct move. I'm an underdog either way this hand but staying makes me a 49% underdog as opposed to a 47% underdog.
