Complete the Bet poker
When an all-in player initiates the betting with a bet that
is less than the current limit, the next player can complete
the bet by bringing it up to the limit. For example, in a $20/$40
hold 'em game, on the last round a player has only $35 remaining,
which he bets. If the next player puts in $40, he has completed
the bet. Clubs have various rulings on whether a player with
less than a full bet may even initiate the betting (or call,
for that matter) and also on whether succeeding players may
just call that amount,
must complete the bet, or are permitted to raise.
