Jacoby 2 Nt

[nilbes]

I've been using jacoby 2nt for years now rather effectively and always thought it as a unvariable standard convention like bergen, reverse bergen, forcing nt,etc.....

This is how I play it:

1 M -2 NT

?: 3 C.....14+ with singleton or any 17-19 balanced hand

3D......5/5 ,5/4 hand or a hand that wantd to know more about P distribution

Partner's 3 H shows dbl. clubs, 3S dbl.D and so forth where you can

even later find out the exact cards of that dbl.

3H......any void

3S......min.hand with singleton

3NT....14+ 6 card suit no sing.

4C......control in this suit min.hand 13-14

4D......same

4H.......same

4S.......lousy hand sign-off

And i haven't found a single person who played it like that so I really think of taking it out of my profile card and that brings me to the topic of how much to write on those cards and then assume that whats written on mine or partners card will be understood equally like an international language lol

some cards have just 2/1 written so I use forcing nt and get a grandious PASS as response ????????partner??????? forcing nt I wail...... response; oh I play 2/1 but no forcing nt!!!!!!

Well this was just the fun part.....

What I really would like to know is how you use jacoby 2nt how it is mostly used by bbo players so that I can adapt myself

i use j 2nt like this

3 clubs/dimonds/other major =(14)15+and 4+cards suit

3 in tromf=6 cards 14+

3 nt=18-19 bal

4=splinter,14(15)+

4 in tromf=minimum

 

but im not sure if all use it like this:)

I have become very fond of the Jacoby Plus system, where the jump to 2NT shows a limit raise in the major OR better. The particular scheme I like is part of the ETM victory system. You can read the response scheme to their JACOBY PLUS system at the following page....

Copied from sayc ok bridge style I think most play this way.

 

If responder jumps to 2NT over a 1♥/1♠ opener, it is J2NT asking opener to show a singleton or void. It shows 13+Points, good support for opener's suit and is game forcing. Opener rebids as follows:

 

1♥/2NT!

3♥! max hand, 18+Points and strong suit

but denies short suit

 

3♣/3♦/3♠! singleton or void in bid suit

 

3NT medium hand, 15-17 Points, denies

short suit (artificial)

 

4♥ minimum hand and denies short suit

 

 

4♣/4♦/4♠! strong 5-card side suit

Either signoff in gameor lookfor slam

Hi Nilbes and all friends,

 

The version of 2NT you've posted was from the excellent book "Better bidding with Bergen". I used to play it for some 4-5 years and it worked pretty well. The only problem was that it required too much memory and might lead to funny contracts when somebody from the pair had forgotten a single bid. Speaking generally I've seen more than 10 different types of developments after 2NT Jacoby raise (most of the world leading partnerships have their own version) so it's hard just to say: "hello partner we play Jacoby 2NT". Anyway the modern tendencies are to use some lower forcing as 2♣ relay and freeing 2NT bid for more limited hands.

Hi Rado :unsure:

Is there any source to check the developments of an efficient version of the 2♣ relay ?

Thx !

Hi Chamaco,

In my view the best way to improve your bidding and play skills is to study world top pairs and to try to develope your style. You may look in CC from last Bermuda Bowl: http://bridgebase.com/yeshoney/

 

Where Italian pairs (Bocchi Duboin for sure) as well as some others use differend kinds of relay 2♣

Chamaco,

von Arnim - Auken, arguably the best women's pair in the world, play the following, but bear in mind that they play a 4 card M, strong C system, with frequent use of canape.

 

1H 2C

2D....5H + 4S or 5H+4C/D or bal 11-13 vul/12-15 NV or s/suited

2H....4H + 5C

2S....4H + 5D

2N....4H + 6C

3C....4H + 6D

3D....6H + 5S

 

May I also suggest you have a look at the structure that Ben, (Inquiry), posted for the use of his 2C/2N structure. I think this is really neat.

Thanks a lot !

I am interested to the 2C relay to be included in a Precision framework, 5 card major, since I believe it it is more justified that responder becomes captain of the auction when the opener is known to be limited.

 

I will check Ben's scheme, do you suggest it also for a strong club system ? Or do you think the von Arnim - Auken scheme can be efficiently moved to a 5 card major system ?

 

Thanks !!! :rolleyes:

First, my treatment using 2♣ is not a relay system. Since you are interested in relays, no need to visit mine. Also, my 2♣ does not irreversibly establish a game force, so opener may indeed be the "stronger hand".

 

My 2♣ bid is basically a part of my bidding philosophy that I want to raise immediately with support and weak hands (my 1M-2M and 1M-3M are both "weak", showing 3 and 4 card support each...although 1M-2M can be some 4 card support hands). My 2NT and jumpshifts are good support hands of one type or another generally with 4 card support. My immediate 3NT and 4NT immediately are strong balanced hands with 3 card support (4NT is not forcing). My 1NT response 100% denies as many as three card support, and is described as "semi-forcing", and never includes even fair game invitational values if balanced. So far, I have had good results with passing this bid when I am weak in my major and balanced.

 

This leaves my first seat 2♣ response. This can include all good three card raises and some weaker constructive 3 card raises (set your limit to whatever you think a constructive raise of 1M-2M should be. What, 9 or 10 hcp? or better). So it can be three card support 9+ hcp (not balanced with 13+ cause 3NT/4NT are available). In addition, it can be a constructive balanced hand without 3 card support (say good 10 up), where you rebid some number of notrump over partner's intial rebid (and taking the good "balanced hands" out of 1NT). Finally, it can be a true 2/1 GF with a real ♣suit. It is easy to separate between these three hand types (fit limit, 2/1 GF, balanced constructive or better). For instance to show balanced guys, rebid NT, to show support and less than GF pass your partner "negative" rebid of 2M, with 2/1 GF bid something else, or if your partner makes the negative rebid, raise the major (showing gf value now with support).

 

I actually think this structure works well within the confines of a precision 5 card major system. It helps with those nagging hands where your partner just feels the urge to open with 9 or 10 hcp as well as the 11 point hands, because now you paly in your 5-3 fit at the two level (after 2♣) and partner's "I have real junk reply (think reverse drury type answer)". It also helps because you can get the clarity on the 1M-1NT auctions (no big balanced hands, no hands with a fit) so you don't have to make 2/1 on some hands that well, might be a stretch but if you bid 1NT first, there is no way to differentiate the near 2/1 GF from the bad ones... remember if your partner can open not only 11 counts but many 10 counts, your 2/1 GF values without a fit really should be stronger than the 2/1 GF response played by other systems.

 

Anyway, if there is interest, I can post my notes on the 2♣ structure. It really is quite different from the use of 2♣ as game force, where the theory is to keep the auction low and allowing maximum room to explorer best strain for game or slam. It takes a different philsophical appoach, wanting to improve low level bidding when light opening are allowed.... something that might interest precision players more than standard 2/1 players. For instance, we end in 2M on a lot of auction that go at other tables 1M-1NT-2m-3M (limit raise values, 3 card support).... our auction goes, 1M-2C-2M-Pass where 2M says, if you have 3 card support and even a limit raise of 11-12 points, 2M is enough. This bid has been remarkably successful for me as the field plays in 3M, which often makes or even makes an overtrick, but when there are only 8 tricks, we clean up. And balancing against this is also dangerous, as responder may have 2 card support and balanced hand and decide to play in the major (or three card support but 11-12 points and balanced).
