Strong Jump Shift

Show 17+ HCP with a 5+ card suit — game-forcing and slam-suggestive.

sequence

1x — 2y (y > x, skipping one level)

how it works

A jump in a new suit by responder — 1♣-2♥, 1♦-2♠, 1♥-2♠, etc. — promises 17+ HCP and a real 5+ card suit. Game forcing with slam interest. Opener rebids naturally (support with 3+, own suit with extras, NT with balanced) and the partnership converges on the best game or slam.
