Examples
The 3 bid shows possession of a club suit and support for partner's heart suit with playing strength comparable to a 3 pre-emptive bid. If, for example, West then bids 3, it is easier for North to judge whether to compete with 4 or not. The 4 shows possession of a diamond suit and support for partner's spade suit with playing strength comparable to a 4 pre-emptive bid. 4 shows possession of a club suit and support for partner's spade suit with playing strength comparable to a 4 preemptive bid. ==Variations==
Variations
The situations where this convention applies vary according to partnership agreement. One variation is to agree that it only applies to non-game jump bids; so, for example, in the auction, 1 - (2) - 4, the 4 bid is natural showing a heart suit and is not fit-seeking and does not show support for partner's spade suit.
