Courtesy Bet poker
A bet made in a situation in which a bet is not mandated, and
sometimes implying a bet that should not be sensibly made. In
a no-limit lowball game, Jim opens and Curly raises. Jim calls
and draws two cards, and Curly draws one Jim makes a smooth
8, and says, "I'll give you a courtesy bet." The bet
is small, and the implication is that Curly will now raise.
A courtesy bet often occurs in the same situation in which a
protection bet is made.
