BART CONVENTION

This concept was devised and developed by Mr. Leslie C. Bart. The original Bart convention was devised to distinguish between a 5-card or 6-card Heart suit after a forcing 1 No Trump resonse. The concept of the Bart convention is an artificial forcing 2 Diamonds bid used in the following sequence.

According to the partnership agreement, this sequence shows various hands, many of them including a 5-card Heart suit. If this is the partnerhip agreement, then the opener will make this assumption. He will then bid 2 Hearts with only a doubleton.

The five hand patterns or types are explained below:

1. The responder has a 5-card Heart suit and a 2-card Spade suit and approximately 8-10 points. The responder plans to pass after any rebid by the opener. The options of the opener are also shown in the example.

2. The responder holds a doubleton Spade honor with 9-11 high card points. The responder will correct a rebid by the opener of 2 Hearts to 2 Spades, pass a rebid of 2 Spades, or raise a 2 No Trump rebid to 3 No Trump. The options of the opener are also shown in the example.

Immediate bids of 2 Spades or 3 Clubs by responder are similar but weaker.
