The jump shift response (17 February 2010)

Jump shift responses (eg 1H-2S) are fairly uncommon, and should be restricted to two types of hand, both showing at least 16 hcp. The first type is where responder has a long solid holding of the jump shift suit, whilst the second is where responder has at least 4 card support for opener, together with at least 5 good cards in the jump shift suit. Jump shifts should not be used where the responder has 2 good suits of his own: these are better shown by reverse responses or Fourth Suit Forcing etc.

In the above Board, the ideal bidding sequence would be: 1H-3C (jump shift)-4C (South can show club support and slam interest immediately)-4D (cue bid showing AD)-4H (AH)-4S (AS)-5D(KD)-7NT (Once South has shown KD, North can count 13 tricks and can bid 7NT rather than 7C).

An enterprising East might butt into the above sequence with a pre-emptive 4S bid, possibly restricting North/South to 6C. If West joins in the action by raising East’s bid to 5S, sacrifices of 6Sx-4(-1100) or even 7Sx-5 (-1400) could be reached, which would probably give excellent match-point scores at tournament level, if the North/South field were generally bidding grand slams. Not for the faint-hearted!
