Blind Open ( poker )
1) A game in which the player to the left of the dealer (the blind) puts in
(usually) one
chip before getting any cards. After all the cards have been dealt,
the player to the left of the blind must either fold, call the opening bet,
or raise.
In some games, this player must come in for a raise (or fold).
2) An opening bet made without looking at one's cards.
