S E F

[Double !]

I have seen many people from France who have S E F written on their profiles but I have not been able to find a good descriptions of the system (I assume this is the standard bidding system in France). I have found "Majeur Cinquieme" online, but I could only find it written en Francais, pas en Anglais. Without having to use a babblefish or some other strange aquatic creature to translate this (I'm not very skilled when it comes to using many aspects of a computer), does anyone know of a site where I can find a reasonable description of S E F in English so I might be able to play with people who only play this system? I speak and understand some French, but I have also forgotten a lot and don't have the knowledge to translate this by myself. ( I can barely speak English coherently!)

 

Thanks a lot in advance.

It is just a simple 5 card major, thik of it lie a sayc, but that has no stupid dark bids who nobody know if they are forcing or not hehe.

 

Ok now to business the system goes this way:

 

5 card major

best minor

 

1/1 is forcing till 1NT

2/1 is forcing till 2NT unless the bidding is 1M-2m-2x-2M wich is 10-11

 

after 1x-1M-1NT 2♣ is 10+ relay (step responses), 2X is weak and 2NT is transfer to 3♣.

 

2♣ opening is 22-23 balanced or semi GF hand, responses are normally natural with 2♦ showing 0-7.

 

2♦ is Gf hand, same responses as 2♣, but 2♥ is now 0-7.

 

michael's cuebid and unnusual NT is std.

 

also standard is toplay landy against opps 1NT (2♣ majors, rest nat).

 

After a reverse, everything but 2NT 'moderateur' is GF

 

I'm not fully sure but I think every 2NT response from opener is GF, and could contain 4 card support. (the only possible exception is 1x-1NT-2NT, rest I am sure are GF).

 

This means that 1M-2x-2M can be 5 cards.

 

That's more or less how it works.

Thank you very much Gonzalo. I appreciate your response.

Also, a great difference with SAYC (as far as I know) :

 

1M - 1NT = NF ! :)

1NT over 1M is nonforcing in SAYC. (It's forcing in 2/1, and some people who play Standard American change it to "semi-forcing", but it's still non-forcing in SAYC. I have posted links to a SAYC card/system notes in other places, so I'll spare you here. :))

Yes, you are right ! Was still asleep ! :)

 

Tx Elianna :)

One or two precisions :

 

1m-1M-1NT-2♣ (it is called ROUDI)

- 2♦ : no support for the major, weak (less than good 13)

- 2M : three cards support, weak

- 2M' : three cards support, maxi (good 13 --> 14)

- 2NT : no support for the major, maxi as above

Beware of 1m-1M-1NT-2NT : normally it is a transfer for 3♣, but for many players, it is natural (11-12)

 

 

No, 2NT rebid by opener is not always GF and always deny four card support in the responder suit.

 

1x-1y-2NT shows 18-20 and denies support for y (if y=M)

1♦-2♣-2NT shows 13-15, responder could pass

(exception ; 2/1 is auto-forcing).

 

Good luck (I hate SEF lol).

mmm I think this is wrong, but I cannot be sure.

 

I've played for many years that 1♦-2♣-2NT is 14-15 or 17+ (when playing 16-18 NT), ,and 1♦-2♣-2♦ is nat or 12-13 balanced. Maybe this is out of the date, or never became standard.

 

for the 1x-1y-2NT thing I really think it is forcing, but I cannot be sure either.

1) 1♦-2♣- ?

 

No real standard, but two approachs :

2♦ to describe a minimum hand (11-13) and 2NT guarantee 14.

 

The point is what to do with a weakish hand over a 2♣ response.

 

BUT classically, the 2NT rebid shows a balanced hand not too good to be open one NT, that is the 12-14 range (almost everybody now in France is playing 1NT 15-17) and this rebid is non forcing (in practice, you pass only with a bad flat 11-count 5332).

 

It is a matter of partnership agreement.

For my part, I play after 1♦-2♣

-2♦ = 11-13, 5+♦

-2NT = 11-13

-2M = 11-14, local force , sole rebid forcing

-3♣ = 11-14, 4+♣

-3NT = 14-17, to play

 

 

2) 1x-1y-2NT

 

No problem with this sequence : it is absolutely non forcing and you deny a 4-card support for y major. Just 18-20 balanced, so responder pass with a bad five-count.

Big hands with support would be rebid with a direct raise (3 or 4), a reverse, or a splinter or 3NT.

For this latter rebid, two schools : either a big 5422 or a flat 4333/4432 (Bessis and Delmouly say 3NT = balanced, Levy says 3NT = 5422).

As you like it. lol

In SEF:

 

1♦ 2♣

2♦ = 11-15, may have 4 card maj or club support

 

1♦ 2♣

3♣ = game forcing, around 15-20

 

1♦ 2♣

2NT = 13-14 (with a balanced 12 or bad 13, open 1 CLUB)

 

1♦ 2♣

2♦ 3♦ = game forcing

 

1♦ 3♣ = 5 clubs + 4 diams, invitational
