Modified Landy

Overview

In Modified Landy:

• 2♣ shows both majors
• 2♦ shows a 4-card major plus a longer minor
• 2♥/♠ promises a minimum of five cards in the bid suit
• 2NT shows both minors
• 3♣/♦ promise a minimum of six cards in the bid suit.

This differs from Multi-Landy [and its close relative Cappelletti] in that there is no artificial bid to show a single-suited [min 6] hand. However, it has the advantage that the 2♦ bid can be used where competing pairs might be using Aspro/Astro etc, whereas the Multi-Landy/Cappelletti players will frequently find they have no [legitimate] bid to make holding a 2-suited hand with only four cards in the major suit. Single-suited hands are handled by bidding the suit in question.

Responsive Bids

Advancer bids 2♣  [no interference]:

This is no different from any other form of Landy, it's just that we normally play the responses by ear rather than having them properly specified.

• Pass is to play, showing a weak hand with long clubs
• 2♦ is a relay, asking advancer to bid his longer major [a rebid of 3♦ by responder is weak with long diamonds]
• 2♥/♠ shows 3+ cards in the bid suit [0-9]
• 2NT is forcing, showing 13+ points with no 4-card major
• 3♣/♦ are forcing bids with length in the bid suit
• 3♥/♠ show 4+ cards in the bid suit [8 losers]. Advancer raises to game with a 6-loser hand.
• 3NT/4♥/4♠ are all to play.

Rebids by Advancer after 2NT from Responder:

• 3♣/♦ shows 5/5 in the majors, 7-10/11+ points respectively
• 3♥/♠ shows 11+ points with 5+ cards in the bid suit, 4 in the other major
• 3NT shows 12-14 points, 4/4 in the majors

If 2♣ is doubled:

•     Pass denies 3-card support for either major
•     Redouble is a forcing relay asking for Advancer's better major, then:
  
  • 2♦ shows equal length
  • 2♥/♠ shows 5+ cards in the bid suit, 4 in the other major
•     2♦ is natural and non-forcing
•     2♥/♠ are to play
•     2NT is natural and invitational, with a stop in doubler's implied suit [if any]

After 1NT - 2♣ - 2♦:

•     Pass shows no interest in competing
•     Double is the same as a 2♦ relay
•     2♥/♠ are to play
•     2NT is the same as the 2NT relay without interference

After 1NT - 2♣ - 2♥/♠:

•    Double is for penalties
•     2NT is natural and invitational
•     Other bids are natural and non-forcing

After 1NT - 2♣ - 2NT [Lebensohl]:

• Double asks for better major
• Pass followed by double is for penalties
• Other bids are natural and non-forcing

Advancer Bids 2♦ [showing a 4-card major with a longer minor, 10-14 HCP, no interference]:

• Pass is to play, weak with long diamonds
• 2♥ shows 3+ cards in hearts [0-10]: to play opposite four hearts; advancer passes or bids 2♠
• 2♠ shows 3+ cards in spades [0-10]: to play opposite four spades; advancer passes or bids his minor
• 2NT is a range ask: advancer bids his minor with a minimum or his major with a maximum
• 3♣ is to play in advancer's minor; advancer passes or corrects
• 3♦ asks for advancer's major
• 3♥/♠ is forcing with 5+ of the bid suit
• 3NT/4♥/♠ are all to play

    After interference:

• double or redouble asks for the major or shows the other major
• 3♣ is pass or correct for the minor
• after 2♦ is doubled:
  • pass is to play if advancer's suit is diamonds
  • redouble is a relay for advancer's major
  • 2♥/♠ are to play
  • 2NT is natural and invitational with a stop in doubler's implied suit [if any]
• after 2♦ is overcalled with 2♥/♠:
  • double shows 4+ cards in the other major
  • 2NT is natural and invitational
  • 3♣ is to play in advancer's minor
  • other bids are natural and forcing
• after 2♦ is overcalled with 2NT [Lebensohl]:
  • double asks for advancer's major
  • pass followed by double is for penalties
  • 3♣ is to play in advancer's minor
  • other bids are natural and forcing
