TransPup lebensohl
(Page of 3)

TransPup lebensohl was developed after a local club game when interference precluded finding fit with 1NT opener’s 5 card major - no awareness if similar method already exists. As with std leb: this applies only for one known suit interference, ‘systems on’ over double/2, 2NT force to 3 is retained. No game testing to debug has been done yet. Thanks to co-author Craig Cordes, who made excellent improvements. Ned Irving and Steve Mackay also helped.

Advantages vs. standard lebensohl:

- GF responder specifies stopper or not

- GF responder uses Puppet Stayman to ask about 4 or 5 card major

- Invite or GF responder with 5 card major uses normal transfers (different paths distinguish invite vs. GF)

- Initial responder double promises GF & stopper – if advancer passes: opener often bids 2NT ‘waiting’, but can pass for penalty or bid natural 5+ card suit

- GF responder has the ability to show a quality minor suit

Part 1: GF Hands

Note: bids shown assume opener bid 2NT after responder initial double. If opener bids 2 or 2 showing 5 card major, transfers are off - responder major would be natural checking for 5-3 fit in that major.

3 is always Puppet Stayman: direct denies stop, after initial double shows stop

3 is transfer to : direct denies stop, after initial double shows stop [exception: when opp suit is , 3 direct shows partial stop]

3 is transfer to : direct denies stop, after initial double shows stop [exception: when opp suit is , 3 direct shows partial stop]

3 direct or after responder double is always quality suit: direct denies stop, after initial double shows stop

3NT direct denies stop, after initial double shows stop

 

The only suit not shown by GF responder so far is :

2NT as initial responder action forces 3, then 3NT follow-up shows quality suit without stop, 3 follow-up shows with stop

Part 2: Invite Hands

The only invite bids are transfer to major after initial 2NT, no info about stop. Other invite hands must decide whether to go for game or not.

Responder starts with 2NT:

3 after forced 3 is a transfer to (when not opponent suit)

3 after forced 3 is a transfer to (when not opponent suit)

Part 3: Pure Competitive Hands

Competitive bids (non-invitational) are just one-suited hands

- Responder can bid a suit direct at the 2 level

- Responder can bid initial 2NT, then pass forced 3

- Responder can bid initial 2NT, then ‘transfer’ into opp suit which shows natural

Part 4: If Opps raise intervention to 3 level after responder initial double or 2NT

4A) When opps raise interference to 3 level after responder initial double or 3

When opps raise to 3 level, opener knowledge of responder hand may be limited. When responder initially doubled: opener knows only responder is GF with stop. When responder initially bid 3 Puppet Stayman: opener knows only responder is GF without stop & without 5 card major. (bids shown for responder 5 card major only apply for initial double case). In a few cases, responder who initially doubled will bid 5 card major natural, as best way to allow check for 5-3 major fits either way.

Opener actions:

1) Direct suit bid by opener promises 5 card major

- After (3) if opener has 5 : 3 shows it, then responder 3 shows 5

- After (3) if opener has 5 : 3 is 5 w/ 2 , 3NT is 5 w/ 3 (responder accepts with 4 when bid was 3NT, responder with 5 accepts with 4)

- After (3) if opener has 5 : 3 shows it

- After (3) if opener has 5 : 3NT shows it (responder accepts with 4)

2) Direct double denies 4 or 5 card major

3) Pass shows 4 card major

Responder follow-up actions:

1) If opener showed 5 card major: other than bids already shown, 3NT is to play

2) If opener denied 4 card major via double: Responder can pass for penalty, bid 3NT to play, bid 3 or 3 natural 5 card, after (3) - responder with 5 must decide from penalty/3NT/4 – 4 would transfer to 4

3) If opener showed 4 card major via pass: responder can double to offer choice to defend or bid 3NT, when opps bid (3) or (3) - opener’s major is known or over (3) when responder has both majors - responder accepts major with 4, when opps bid (3) - responder can bid 5 card major

4B) When opps raise interference to 3 level after responder initial 2NT

Opener direct actions:

     Pass (2NT responder does not promise a good hand)

Responder follow-up actions:

1) After (3): Double shows invite hand with five , 3 shows invite hand with 5 (simple accept by opener denies game interest)

2) After (3) or (3), Double shows invite in other major

3) After any 3 level interference: 3NT shows GF with (3, if available, would show with stopper)

4) Pass shows less than invitational hand

----------

Method Comment:

If willing to add complexity, responder could immediately show GF five card major with stop or not. Direct cue bid denies stop & unbid 3 level suit shows stop. Note that unbid does not count 3, which is reserved for Puppet stayman. Major is always defined except when cuebid is 3, major fit could be sorted out when opener is interested.
