Chop-Chop poker
1) Split a pot in a high-low game.
2) Make an agreement among two (sometimes, rarely, more)
to split a pot without having a showdown.
3) Put a chip up for the dealer (as a toke), and instruct the
dealer to take half.
For example, a player wins a pot, throws the dealer a dollar
chip, and says, "Chop-chop";
he wants the dealer to take 50 cents and give him back 50 cents.
