Hi all.

I have been thinking.

In the sequence 1♣ 1N 2♦, with 2♦ as a Jacoby transfer should responder's rebid depend entirely on his strength in ♥s.

Eg

2♥ if minimum with 8 hcp and no fit
3♥ if minimum with 3/4 card support
4 ♥ if 9-10 and with 3/4 card support.

I came up with this schema rather quickly but I am sure if it is any good it is being used and if it is not then I need to know what is.

Any thoughts on either point.

All relevant responses much appreciated.

I don't get the point. When will opener want to transfer a suit he can hardly have, and when will responder ever have 4 card support in a suit he already skipped?

Hi,

#1 I guess 1C is artifical, in a strong 1C system context
#2 1NT showes 8-10 and a bal. hand

This takes the forum into account, but it may behelpful to
write it in the post.

I have no experiece with strong 1C systems, but given the
conditions, it may make sense, to play the same system after
a 1NT reponse as after a 1NT opening.

The only difference is, that the systems after a 1NT opening
bid usually let responder describe his hand, and than the 1NT
oening bidder becomes captain.
This translates to the fact, that the strong hand describes his
hand, and that the weaker hand becomes captain, usually strong
1C system make the 1C opener captain.

So if you dont care a lot about right sidening the contract and
telling the opening leader too much, ... the response scheme after
a 1NT opening will work in the given situation.

With kind regards

Why are you transferring to make the weaker hand the declarer?

Yeah. This is very bad. Also, the 1N response should not be used for a hand that is likely to end up in no trump.
We use it (in a relay system) to show both majors. A lot of people play that a 1N response shows clubs (which is ok when opener gets to play club contracts but again not so good for NT contracts).

Here's Meckwell's structure (from what I recall). It's just one example of how to organize so that opener frequently gets to play the contract.

1D-0-7
1H-8+ with 5 spades OR 11-13 balanced
1S-8+ with 5 hearts
1N-8+ with 5 clubs
2C-8+ with 5 diamonds
2D-8-10 balanced
2H-14+ balanced
etc for 4441s etc

Relay responses are probably more efficient if you want to go there. An example of this (not the best one) is...

1D-0-7
1H-4+ spades, unbalanced
1S-balanced or minors
1N-4+ hearts, unbalanced
2C-hearts and diamonds
2D-clubs
2H-3-suited with both minors
etc-diamonds
