Jump responses at two-level to one-level suit openings are slam tries. Since there is no chance for opener to show his limit, the player who made the jump response must have a standard hand and describe his distribution with his rebid. The jump responses can be used with limited strength and either single suited hands or balanced hands with good five-card suit. In addition, it is possible to use the jump response with good five-card suit and fit to the opening suit. Jump response with two suited hands beside the opening suit creates problem by shortening the bidding space and not giving chance for each side to show their limits. It is best to start the bidding at one-level with this type of hands.
