Money Talks

There are a lot of components to a bluff. Somebody who can face act really well does have a substantial tool in their personal arsenal, but so does somebody whose face moves about as much as a person who has botox running through their veins instead of blood. Tantrums, rolling eyes, twitches, etc are all components to try to sell the bluff, but the most powerful component to make your deception successful is financial. When you're bluffing, what you are fundamentally doing is playing chicken with your chips.
