Robson rules: When a team wins all five tricks (normally or by going alone), they may choose to reduce the opposing team's score (by two or four, respectively) instead of adding to their own score. Additionally, if the dealer turns up a jack on the kitty, they may elect to go alone without seeing the rest of their hand. If all tricks are won via this "blind loner" hand, five points are awarded instead of the usual four; but a failure to win all tricks earns the defenders one point. This rule set was named for four-time Northern Michigan regional tournament runner-up champion James Robson.
