JAZZ BRIDGE 1NT

 

12-15 honorpoints, balanced without a 4 card major.

 

  • Opponents who double the opening could be a problem but also here a sufficient re-action exists : (Helvic-convention) 2x means a two suiter (4-5 /4-5) in x and x+1. Pass means either 9+hp, either weaker with a 2 shape-suiter (♠♦ or ♥♣). Redouble means a 5 card in unkown suit and expects opener to bid 2♣ only if his RHO passes.
  • a partner with a relative weak hand and with a 5 card can escape with 2♣ (DUKE-convention), forcing the opener to bid 2♦ . Partner will now pass or bid his 5card suit.
  • a partner with 10+hp without a 5 card major will bid 2♦ (relay). The answer of opener will reveal his hand with a 6-step answer. ("sixpack"-convention)
  • a partner with 10+hps and a 5+card major bids his major : 2♥/♠

The opener who ALWAYS holds 2-3 or 3-3 major shows via a 6 step answer whether he has a fit (3card) and his strength (min/:max).

General common sense

 

  • Bridge is about scoring either by finding and making the best paid contract, either by making the opponents to score less
  • In descending order of priority we search for
  • the highest major contract
  • the highest NT contract
  • the highest minor contract
  • when making choices along the bidding lines we take into account the highest probabilties.
  • the stronger the hand, the lower the openingsbid, creating bidding space.
  • simplicity before complexity

 

1♣- NEOSQUEEZE

 

All hands from 16+hp onwards or equal via a special distribution : Zarpoints 32+ zp.

 

The opener is the leader of the auction and takes initiatives. His partner answers his questions. The bidding space is optimally used via steps .Without overcalls and before 3NT is reached, the opener will know the distribution and strength of his partner. This is possible to due to a strict first-round answering scheme and the Relative Suit Code convention that allows the partner to indicate suits in a stepwise, abstract manner.

2 level MULTI bids

 

  • 2♣

- or weak with both majors (4-4, 4-5, 5-5) , <26zp

- or strong, balanced, 22-23 hp

 

  • 2♦

- or weak with 6card major, <26zp

- or strong, balanced with 20-21 hp

 

  • 2♥/♠

- or Muiderberg (5c ♥/♠ + 4+c minor, weak)

- or weak 6c♥/♠ with 4 card OM

JAZZ BRIDGE 1♥/♠

 

  • A natural five card opening from 12 till 15hps (< 32zps). We apply 1 strong (10-15hp) relay bid : 2♣

A stronger partner (15+) with fit can show this hand via the DUKE-convention.

 

  • We define a gate for long weak suits (the DUKE-convention of the 1 major opening) : 1NT . The opener is obliged to bid 2♣ P/C.

 

  • A weak partner will enhance the opening bid also with a 2 card fit. With less (sn or void) he applies the Duke.

 

  • In stead of Bergen-raises we apply an alternative : the Jazz-raises.

JAZZ BRIDGE 1♦

 

  • It is important to find a majorfit as soon as possible. After all, major contracts pay best and.. they have the highest hierarchy in the bidding level. Therefore, we place all hands with a 4 card major behind the 1♦ -opening in order to allow partner to bid very economic his 4+ card major, already from 6hps onwards . More, also unbalanced hands without a 4 card major are bid via 1♦.
  • The partner with a 4 card major always replies with 1♥ (hearts OR spades). The opener rebids his 4 card major with 1♠ if spades and 1NT if hearts. The major fit, if any, is found very fast.
  • A partner without a 4 card major will either bid 1♠ (DUKE-convention) either 1NT/2♣ to show 10+hps with 5c ♣/♦

 

 

Jazz' Ace Request 4NT

 

5♣ : 0-3 aces

5♦ : 1-4 aces

5♥ : 2 aces with 0-3 kings

5♠ : 2 aces with 1-4 kings

 

the DUKE-convention

 

  • designed for showing a weak 5+card at partner or a two-suiter with 10-11 hp
  • only possible after 1♦ with 1♠ , after 1M with 1NT and after 1NT with 2♣ .

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  • After a 1major opening the Duke is typically applied when having a sn or less in openers major. The partner wants to play in another suit on the 2-level, hoping for a better fit, NF. Via Duke he can also show all remaining 2 suiters. Because the 3-level is reached, a minimum of 10hps is required.

 

  • After a 1♦ and a 1NT opening, no suit is known at openers side. Therefore, the Duke-bid announces either a weak 5+card in one of the suits , which will be bid after openers obligatory response. Also here, partner can show all remaining two suiters of 10-11hp.

Duke Ellington

 

Duke Ellington (°1899) was a famous coloured bandleader and jazzcomposer with more than 2000 songs in his songbookt. He experimented often with mutes and growling saxofones to discover new tonalities. He also made (1960) a big band version of the Peer-Gynt–suite. He died in 1974.
