The Pulsating Vein Tell

[andyfox]

I don't see how it's the same as taking advantage of a player who has shaking hands and therefore can't protect his cards well. That player does it every hand and is actually showing his cards to his neighbor(s). The pulsating vein is a physical reaction, like breathing heavier, or dilating pupils, to a particular hand.

If the player with the pulsating vein would take lessons from a master reader, that teacher would pick up on the pulsating vein and train the player either to control it or to cover it up with some kind of headwear.
