Sandbagger

The best seat is in front of players who open freely and raise freely, and behind any sandbaggers (players who pass strong hands and then raise when someone else opens). “Openers to your left, sandbaggers to your right.” This is especially true in a limit game.

Now I don’t wish ill will on any golfer — well, maybe that one sandbagger in my weekly league — but there’s something about watching players with perfect swings and the utmost talent intimidated by an expanse of water just like the rest of us.

The poker sandbagger would, upon being dealt a fantastic hand, delay upping the ante in order to lull the other players into a false sense of security.

The Day-Globe, Waco, Texas, July 5th., 1893, writing on "The Conscienceless Juror," says: […] 'Red Farrel' a notorious sandbagger and robber was on trial in Judge Moise's Court.

The American sandbagger, like so many others (including the mugger), evoked the street robber's violent technique. It was from sandbag, to ambush or hit without warning: whether an actual sandbag ever entered the picture was irrelevant.
