Lesson Notes: The Negative Double

NEGATIVE DOUBLES (RESPONDER’S DOUBLE)

When partner opens one of a suit, and right hand opponent overcalls, e.g.1 (overcall 1♠), a double by the next hand (opener’s partner, the responder)is a negative double. It’s meant for take-out, not penalty. It shows somepoints, but often not enough to bid naturally at the next level. A negativedouble asks partner, the opener, to bid something, so the higher the level ofthe double, the stronger you need to be. Remember “pass” is an option too…
A negative double denies three things, so make a mental check that thesethree conditions are present, and if so, the answer will be “double”.

You won’t have:

  • a fit for partner. (in competitive auctions, showing a fit is first priority)
  • a stopper in the overcall to be able to bid no trumps
  • the ability to show your suit/s at the appropriate level, either because youdon’t have enough points, or you have two suits, and would like to showthem both

NB: With a five+ card suit and 10+ pts, responder bids their suit rather thandoubling e.g. 1 (overcall 2♣) 2♠ by responder shows 10+ points and isforcing. If responder doesn’t have enough strength to do that, start with anegative double, planning to bid the suit at the next opportunity. NB: 1♣(overcall 1) X would show four spades, and that leaves a 1♠ bid to showfive + spades.

Opener’s Rebid After a Negative Double
(Opener must show their own strength when rebidding)

  • With a minimum hand (13-15), opener will rebid at the cheapest levelavailable. Opener may pass if the next opponent competes after thenegative double. 1 (overcall 1♠) X 2♠ Now opener passes. This shows aminimum hand where opener couldn’t bid over the opponents’ 2♠.(Responder’s negative X showed the minors)
  • With a medium hand (16-18), opener jumps a level, or bids even if the nextopponent competes after the negative double: 1 (overcall 1♠) X 2♠.Opener now bids 3♣/ = medium hand, could have passed, but didn’t.
  • With a maximum hand (19-20), opener takes the partnership to game, cue-bidding the opponent’s suit if in doubt about the best contract: 1 (overcall 1♠) X 2♠. Opener now goes to game if they know which minor toplay in, ie 5♣/ OR
  • 1 (overcall 1♠) X 2♠ 3♠. Opener’s cue bid here, of the opponents’ suit,shows a good hand, but not sure where to play.


Quick Tips:

  • A negative double, responder’s double, is made after an opponentovercalls opener’s bid
  • The higher the overcall, the stronger the doubler needs to be; each levelhigher requires the equivalent of a king more (ie 3 points)
  • A negative double denies a fit for partner because showing a fit is firstpriority in competitive auctions
  • A negative double denies a stopper for no trumps
  • A negative double shows a hand that’s hard to describe (not enoughpoints to show the suit, or two suits)
  • If responder passes, opener should try to reopen with double, becauseresponder may hold the opponents’ trumps
  • 1♣ (1 overcall) X (double) = precisely four hearts and four spades
  • 1♣ (1 overcall) 1/♠ = four + hearts /spades
  • 1♣ (1 overcall) X (double) = four spades
  • 1♣ (1 overcall) 1♠ = five + spades
  • 1♣ (1♠overcall) X (double) four + hearts (denies enough hearts, or points,to bid a forcing 2)
