Spotter ( poker )

A card 4 through 10. When one of these cards is lying face down, and you lift the lower right corner, you can see spots in the corner (as opposed to a no-spotter, which has no spots in the corner, or a liner, which is a face card). Some lowball players couple the knowledge that a card could be one of these (but that they don't know which one) with game theory to decide on whether or not to bet. (Impartial observers might say they're just playing games with themselves, but we don't make judgments; we just define terms.)
