Over Blind ( poker )

1) Put in a blind when one is already present. In a traveling blind game, this could mean someone putting in an optional blind in addition to the mandatory blinds. In a game without mandatory blinds, this would be blinding a pot (putting in a blind) after someone else has killed it. (To put in an over blind is sometimes called to kill.) Sometimes called go the overs.
2) The blind put in by the person who over blinds. In a 3-3-6 traveling blind game ($12 limit or $12 minimum bet no-limit), John might put in $12 before getting his cards. He has doubled the limit (or the minimum bet) to $24, and he gets last action before the draw. Someone might say, "John acts last; he has the over blind." Also straddle, for both meanings.
