Usage:

This occurs most frequently in lowball, in which a player draws one or more cards and, on the second round of betting, bets before receiving the card or cards. This is done usually for the purpose of stimulating action, but sometimes to discourage an opponent from raising. Sometimes players claim to bet blind but have actually seen their draw card or cards; doing this is considered bad form, and gives the claimant a bad reputation. The term is also heard in seven-card stud, with a player betting before receiving the river card, or in hold'em before the river card is dealt.
