Shooting is an approach in bridge to the bidding or play of a hand which aims for a favorable result by making a choice that is slightly against the odds. A player might decide to shoot toward the end of a pairs game, when he judges that he needs tops to win, not just average-plus results.
Shooting is generally considered an ethical maneuver when it is used sparingly in an attempt to improve one's score. It is regarded as contrary to the proprieties if a player, perhaps angry with his partner, starts bidding and playing every hand in ways that disregard winning technique.
In contrast, a player who is shooting makes a bid or play that is only slightly inferior, in the hope that the cards lie in such a way that the normal, percentage action will lose. In the long run, even slightly inferior actions lose to the better bid or play, so it is not sensible to shoot unless the only hope left is an unusual situation, such as a 4–1 instead of a 3–2 trump break, or a normal 3NT contract that goes down on normal play.
Although it is possible to shoot in either the bidding or the play, authorities disagree on whether it is wise to do so in the bidding. For example, Marshall Miles has written that "There is no way to estimate the effects of weird bidding on a particular hand, and it is almost impossible to start shooting in the bidding without having partnership confidence suffer."[1]
On the other hand, if shooting, Hugh Kelsey recommends[2] a pass with ♠ 6 ♥ A J 7 2 ♦ K J 8 4 3 ♣ K 4 2 over RHO's opening bid of 1♠. Kelsey notes that everyone else will double, because in the long run it is the best call. But if LHO has a good redouble, or if the takeout double leads to an unmakeable game, or if declarer misguesses because you pass, then you might get a very good result (more often, you'll get a bottom). Notice that Kelsey's suggestion conforms to the basic notion of taking an action that is slightly against the odds. To pass with a much stronger hand would be far too extreme an action.
