I'm looking for two things in this post/thread:

1) A general outlook/system/plan (to "How do people deal with
interference over their 1N openings)
2) Answers to a specific set of questions

The specific question is: Suppose you have a typical hand with 5 hearts
where strength is weak/intermediate/strong (where we interpret these terms
to mean "signoff/invitation/forcing" in the context of whatever your opening
1N range is). Partner opens 1N, next hand bids 2S, what do you do with each
of these hands? Note that in all cases, had there been no interference,
you'd have started with a 2D transfer. But now what?

Some of the more common characteristics of Asperger syndrome include:

* Inability to think in abstract ways (eg: puns, jokes, sarcasm, etc)
* Difficulties in empathising with others
* Problems with understanding another person's point of view
* Hampered conversational ability
* Problems with controlling feelings such as anger, depression
and anxiety
* Adherence to routines and schedules, and stress if expected routine
is disrupted
* Inability to manage appropriate social conduct
* Delayed understanding of sexual codes of conduct
* A narrow field of interests. For example a person with Asperger
syndrome may focus on learning all there is to know about
baseball statistics, politics or television shows.
* Anger and aggression when things do not happen as they want
* Sensitivity to criticism
* Eccentricity
* Behaviour varies from mildly unusual to quite aggressive
and difficult

I play weak no-trump without transfers,
but, for what it's worth ---

Weak
----
2NT (Lebensohl) 3C
3H

Invitational
------------
DBL (Negative) ?
3H

Game Forcing
------------
3H

I think this also makes sense playing
15-17 NT with transfers since you can
no longer show the strong minor suit
hands via Stayman and need 3m for your
minor suit slams.

Wow, 100% agree :)
Don't know how transfers come into all this, you do NOT play "stolen
bid" pls!

.................................................................

Play transfers from 2N to 3S:

2 of a suit = to play
x := T/O
2N/3C/3D/3H = transfer to next suit up
3S = values for 3N but dubious stop
3N to play

If your transfer is to the oppo suit it is stayman - without 4 cards in an
unbid major partner completes the transfer with no stop or bids 3N with a
stop.

If you transfer to a suit available at the 2 level it is invite+ else could
be weak so do not break without thought.

with 5-4 shape and GF transfer to 5 carder then bid the 4 carder.

Optional extras:
4 any = slam try (so always transfer and raise to play in 4M).

This allows you compete with weak hands and show good hands with 1, 2 or 3
suits and find 4-4 major fits and find if you have a stop for 3N.

Indeed, I usually play pretty much the same in a Strong NT auction

With five-only Hearts and a weak hand, I would probably go quietly via
a pass. However, I COULD sign off in 3H via a Lebensohl relay.
With an intermediate-strength hand that is not suitable for a penalty
double of 2S, I have to decide whether to treat it as competitive as
above or to force to game.
With a game-forcing hand, I bid 3H directly.

What I use is:
DBL = 8+, balanced -- opener can bid or pass as looks best
2 of suit = to play
3 of suit = forcing
cue-bid = Stayman
2NT: lebensohl, relay to 3C, typically planning to pass or correct to
another suit
3NT: to play, includes a stopper since a non-stopper hand could double or
make a forcing bid in a suit

In a set partnership I'd probably favor the Rubensohl approach (transfers
starting at 2NT.)

Incidentally, this is known (in the big bad real world) as Rubensohl, right?

Or did you change anything from that available in published sources (e.g.,
http://en.wikipedia.org/wiki/Rubensohl) ?

Wrong. It is only OCCASIONALLY a discussion group

Transfers into opps suits are staymanic and stopper asking. Immediate

The concept of playing 2NT+ as transfers is certainly known as
Rubensohl, but there are lots of ways to implement it. For example,
we play double as doubleton take-out so have no need for a Stayman
bid, instead we transfer to their suit to show a 3-suiter with a
singleton or void. The 3S bid ('transfer to 3NT') has various
meanings depending on the overcall e.g. after 1NT (2D natural) 3S is
5-4 majors game forcing but after 1NT (2S natural) it is a 3-suiter
with 4 hearts and the transfer to 3S is a 3-suiter with 3 hearts while
after 1NT (2C majors) 3S is FG both minors.

1. Pass if the hand is genuinely weak. If I have enough to want to
bid at the 3-level, 3D showing hearts, competitive values. I would
usually have 6 hearts for this, so it has to be a sensible suit.

2. 3D transfer to hearts and either pass or treat it as game forcing.

3. EITHER 3D transfer to hearts then either cue bid (with no spade
stop) or 3NT (choice of games), OR take-out double followed by 3H.
Depends on vulnerability and how hearty the hand is.

The weak/invitational type hand might also prefer to make a take-out
double, e.g. Jx 10xxxx Kxx KJx looks like a double of 2S to me.
