The Bridge Convention is a world class event.
The card game contract bridge, also called Hamilton and Pottage, is a bridge bidding convention used to interfere over opponent's one notrump (1NT) opening.The origin of the concept is claimed by Fred Hamilton, John Pottage, and Gerald Helms.[3]
It is a defensive bidding convention that can be used against a weak 1NT opening.[4]
It maximizes the partnership's chance of finding its best fit quickly by allowing over caller to show a variety of two-suited hands.
The over-calling opponent makes one of the following bids over the 1NT opening.
A Double for penalties by Intervener is recommended if you have 15 or more points.There are points by partnership agreement.
This variant is similar to the Multi-Landy convention for hands with both majors.
The power of this convention, rather than making a simple overcall, comes from its focus on showing two suited hands to partner and finding the best partnership fit between those two suits.It's necessary to be aware of all 'conventional' bids and responses.
A Cappelletti overcall is usually made from second seat but if second and third seat pass, then fourth seat can also intervene.The fourth seat would want their holding to be towards the upper end of the Cappelletti points range in order to make such a call.
Over-calling opponent 'Intervener' makes one of the following artificial bids to indicate a one- or two-suited hand.
With a strong hand of his own, Advancer may think that the defensive partnership could call their own game.
Any bid by Advancer beyond the natural conclusion of the Intervener calls is an invitation to game.
If the advancer makes a 3-level bid in a suit ranking above the 'Cappelletti' suit, there may be no exit bidding short of a Game Call anyways.
When the defender's own game call is likely to be 3NT is the most useful circumstance for this.The following scenarios should be looked at.
If Advancer's holding is 14+ HCP and with stops in the other suits, they might ask Intervener if they are top.'.
Intervener can either pass or sign off by re-bidding his own suit.
Intervener advances to a game call of 3NT with a partnership holding of at least 25 HCPs.
If Advancer has a shortage in the Capelletti suit then 3NT is passed, but with support for partner's major suit, then sign-off.
If the Cappelletti suit is a minor, it is unlikely that you would want to go beyond 3NT.
Intervener should be asked if he is top or bottom of his points range partner if Advancer is holding 14 HCP+ and three cards in hearts.'.
Intervener now assesses his shortage points using the method of 'Losing Trick Count' and decides whether to pass 3 or sign-off with a game call of 4.
