  1. Improvers Week 14 The Use of Doubles (Part 2)

  2. Doubles • Last Week • TOX • Negative Doubles • This Week • Protective/Balancing Doubles • Lead Directing Doubles • Doubles over NT bids • Lightner Doubles • Penalty Doubles

  3. Protective or Balancing Doubles • Same thing – 2 names • A form of TOX • Leaving opponents in 2 of an agreed suit is a losing strategy • Especially a major • They usually make it • Often you have as many points and a fit • If you pass in 4th seat it will be their contract • But your hand does not fit the usual TOX requirements • We make a protective double

  4. Protective Double Example • The bidding goes: • 1P 2 • P P ? • If you Pass now they play the contract • You have 10 HCP • What do you bid? • * • Protective so they have to go to 3 for the contract • Pass whatever partner bids • Almost certainly one of the majors  K  7  6  Q  8  3  A  5  3  J  T  9  3

  5. Protective Doubles • Natural TOX not alertable • Just to push opponents up a bit • If you play you make it half the time • The other half go 1 off • Better than them making a part score • Beware known under-bidders • Let them play • If partner makes a protective double bid your longest suit and never go on unless partner makes a strong bid • Do NOT punish partner for competing

  6. Lead Directing Doubles • RHO makes a bid • And it is a conventional bid • E.G. 1NT P 2announced as‘s • You have good‘s • And would like partner to know that you would like them led • Double the 2bid • Partner alerts as a lead directing double • Cannot be TOX – partner would not know which suits you mean

  7. Lead Directing Doubles • Very straightforward • Just says “Please lead this suit” • A safe bid • Opponents must bid again • You have made life easier for partner • Who never seems to lead your suit! • Now there’s no excuse

  8. Lead Directing*- example 1  7  6 • LHO opens 1NT • Partner Passes • RHO bids 2announced as‘s • You * • Partner will lead a • Which should also signal what to lead back! • Less than 6 for low suit • More than 6 for high suit  8  3  2  A  K  T  3  2  J  T  9

  9. Lead Directing*- example 2  7  6  3 • The bidding goes: • 2P 3P • 3P 4P • 4NT P 5? • 4NT is RKCB • 5shows 3 or 0 key cards • What do you bid? • * Lead directing • They must bid again  J  T  6  2  J  T  6  3  A  Q

  10. Lead Directing Doubles • Very easy to tell partner which suit to lead • Do NOT do a lead directing * if they have bid this suit naturally • Because they might Pass • Any double of a conventional bid is lead directing and should be alerted if below 3NT

  11. Doubles of NT Bids • All doubles of NT bids are for penalties • Considered the norm and does not need alerting • With 16+ HCP you should always double a 1NT bid for penalties • In 4th seat after 1NT P P you should double with 14+ HCP

  12. Doubling NT Bids – example 1  A  Q  J  9  3 • RHO opens 1NT • You have 17 HCP • You should * for penalties • Not bid 2 • More profitable if they play and go off  A  T  6  K  9  K  7  2

  13. Doubling NT Bids – example 2  Q  J  9  3 • LHO opens 1NT • Partner and RHO Pass • You have 15 HCP • You should * for penalties • If you Pass they get the contract when your side may have more strength • 1 or 2 off may be a good result for them  A  T  6  K  9  K  Q  6  2

  14. Doubles over 1NT • If your partner doubles 1NT • You should only bid a suit if very weak (Less than 6 HCP) • Any suit bid shows a weak hand • NB If your side doubles a suit bid after already doubling a NT bid that is also for penalties.

  15. Lightner Doubles • A special double against slam bids • When partner is on lead • Says “Lead an unusual suit” • Usually first bid by opponents

  16. Lightner Double – example  T  7  2 • The bidding goes: • P 1P 3 • P 3 P 4NT • P 5P 6 • ? • They stopped in 6 so partner may have an Ace • If you can get a ruff they go 1 off • So * for an unusual lead • Tells partner to lead a  8  6  5  4  2  8  6  5  3  2

  17. Penalty Doubles • The Doubles we have looked at are mainly used where we would not expect to make a penalty double • We can still double for penalty: • Over NT contracts • When opponents over-reach to game • 5 level contracts – especially if opponents are sacrificing • 3 level contracts when you have pushed them too far

  18. Doubles • We have looked at a number of types • You should use • TOX • Negative • Lead Directing • It would be good to use • Protective/Balancing • Perhaps a step too far • Lightner
