I understand that after a double of weak 2 bid Lebensohl can be employed to distinguish between weak and strong bids by advancer.I request all to suggest continuations by advancer and doubler after the double .

'Request' is a slightly odd word to use here. You are basically asking for a favour from us.

to make up for my grammar Nazism, I will try to describe as well as I can my favourite structure:

2♦-x-p-2NT=natural

2♥-x-p-2NT=lebensohl, then (p-3♣-p-):
3♦=weak hand with clubs
3♦=weak hand with diamonds
3♥=4 spades and a ♥ stop
3♠=4-5 spades, invitational
3NT=choice of games with 4 spades (I think! I read this on the forums at one point)

instead of 2NT:
2♠=weak
3♣=about 8-10 with clubs
3♦=about 8-10 with clubs
3♥=GF. two places to play or looking for a heart stop. or some other hand that I can't think of right now.
3♠=forcing with spades
3NT=to play, with a heart stop
4♣=forcing with clubs
4♦=forcing with clubs
4♠=non-forcing with spades

2♠-x-p-2N: just about the same as above. there is more of a need for the 2NT..3♠, 2NT..3NT, sequences because there's less space to bid hearts. 2♠-x-p-3♠ definitely does not promise four hearts, doubler should bid suits up the line or 3NT with a stop.

Doubler should decline to bid 3♣ if he has a long suit and extras, or cuebid if he has a very strong double (like 17+).

Here's what I like to play:

(2♦)-X-(P)-...

2♥/2♠ - a non-invitational hand, natural
3♣ - 8-11ish, if I only have 8, I'll have a redeeming feature, like a decent 5 card suit
3♦ - game forcing, strain in question or some slam interest
3♥/3♠ - invitational, 5+ in the bid suit
3N - to play
4♦ - bid your better major


(continuation of previous auction)
2N-(P)-3♣-(P)-...

P - bad hand with clubs
3♦ - slam try, strain in question
3♥/3♠ - invitational (9-11 ish) with exactly 4 of the bid suit
3N - a 3N bid with extras, something that would have slam interest if you broke the lebensohl relay
4♣ - strong slam try in clubs
4♦ - slam try both majors
4♥/4♠ - mild slam try with single-suited major hand

You can probably extrapolate what I'd do with lebensohl over all other openings than 2♦ from this, it's all very similar.

That's what "request" means.

To make up for my mistaken grammar nazism let me add that jdonn plays 2NT as always a weak hand and non-forcing (says nothing about stoppers). Sometimes doubler has a slightly offshape hand and 2NT is not a bad contract.

After 2♥ dbl pass we play as follows:

2♠ weak
2NT lebensohl
3 minor natural, constructive, NF
3♥ game forcing, if only to game denies a heart stop and promises 4 spades but might have slam interest without 4 spades
3♠ invitational with 5 spades
3NT to play, not expecting partner to bid again without a slam try
4 minor natural and forcing
4♥ good 4♠ bid
4♠ to play no particular slam interest
4NT natural invitational
5m to play
5♥ 2-suited spades + a minor slam force
5♠ random slam try (4♥ either weaker or stronger)
5NT pick a minor
6 non-hearts to play
6♥ undiscussed


After 2NT, doubler bids non-3C with extras; 3D♦ is strong but NF; 3M is forcing. Advancer has to make his own arrangements if he didn't have a weak hand.
After 2NT-3C then
P/3♦ to play
3♥ game forcing, 4 spades & heart stop (usually just COG)
3♠ invitational with 4 spades
3NT to play, but suggests doubt (usually only one heart stop and a 5/6 card minor)
4♣/4♦ game forcing, 6 card suit + 4card spade suit
4♥ 5 spades + 5 card minor
4♠ mild slam try
5 minor mild slam try (a bit obscure as you could have bid 4m forcing last round)

others undiscussed, sorry(!)
