Everyone loves to gamble. Bridge is a gambling game, although it is considered unmannered to play for money. To take guessing out of the equation and the auction, conventions and logical treatments, etc. have been invented, devised and created. However, the Gambling Three No Trump Convention is used to obstruct the opponents because it takes up so much bidding space.

The Gambling Three No Trump bid is a feature of the Acol System and has been adopted by bridge players using the Two Clubs Strong Artificial Opening bid. The Gambling Three No Trump bid is an opening bid based on a long solid Minor Suit, with at least one, preferably two, outside stoppers. Take a look at the following hand.

3 No Trump
With this hand the opener would bid 3 No Trump.
