Yet another system style

[mike777]

In the spirit of the other system posts and New year eve's drinking.

 

Here is my buddies 2/1 style which he is teaching me. I do not know 2/1 or any Bergen, so for me all of this stuff is now "standard 2/1".

 

1) light opening, all 11 HCP and some 10's and rare 9/8/HCP.

2) 2/1=14+ (conservative 2/1) shape showing rebids as opposed to strength.

3) 1nt=14-16 off shape ok, gadgets etc.

4) 2d=18-19 bal. off shape ok, gadgets etc.

5) 5 card majors with bergen raises(conservative upgrade) and other gadget raises.

6) minor suit openings with gadget (conservative) raises and cosmic gadget weak 2 suit major showing convention.

7) forcing nt(13hcp) over majors (conservative)

8) over minor suit openings nt resp. are upgraded.( conservative)

9) gadget kickback stuff.

10) weak 2h/2s (Jimmy will love this part).

 

Advantages

1) makes me play the hands better since we get up there pretty fast.

2) Light openings sometimes makes opp. overbid or underbid.

3) 14-16 nt has a bit more preemptive effect compared to 15-17.

 

Disadvantages

1) makes me play hands better since we get up there pretty fast.

2) Light openings sometimes makes opp. overbid or underbid.

3) 14-16 nt openings may not work out.

Out of curiousity, just how often does responder have a hand suitable for a 2/1 response to your light 1 level openings???

[the hog]

Are you asking for comments on this?

If so - some of the disadvs you pose are actually advantages eg opps overbidding. The worst aspect about which Richard has already intimated, is the 14+ 2/1. This means your 1NT response will show from 6-13 balanced. I don't see how this is playable.

 

I also don't like your 2D opening at all - you will be playing in 2NT when those who have sound structures will be playing in 1.

[mike777]

Yes, looking for comments.

 

Ty for your kind and prompt replies.

2D, we can get out at 2s if partner has weak hand with spades, if not and p has 0-4 hcp balanced hand and if opp do not overcall(they frequently do) we will play 2nt with 18/19 across from 0-weak balanced.

 

1nt forcing range over majors: natural rebids but gadget 1s=1nt=2c.

Only limited experience, so far opp seem to overcall if they have pts or we are able to stop at very low level when both hands very weak. Good concern though, interesting to see how such a wide response works out in practice.

Looks nice.

The 2d 18-19 bal is played by many italians ,boochi dubin switch between the 2c and 2d (2d is GF, 2c is 18-19 bal) so i guess its alright.

The special part is your light opening, its just normal that your 2/1 will need more hcp.

Your adv is opening light which might be good in competetive.

Your disadv is that your 1 level opening are witdh and handling it wont be easy, especially the 1nt forcing which is 6-13, but maybe its possible.

It might be a good idea to try and unload some of those hands which bids 1nt in your system. The are some ways i know to do this are :

1: 2/1 are GF except rebid.(or maybe its just better to play only 1RF when openings are so light)

2: add the invite 3 card supprt into your bergen's bid (ex. bid 3c with either 6-9 4 card supprt or 10-11 3 cards support)

3: Ben posted his 2c over 1M which is kind of a weak relay, i think some play 2d as all invitationals realy.

[mike777]

Thanks for input Flame.

 

2D can be a double edged sword.

 

1) Buddy insists all 2/1=100% game force. I like it because it is clear and simple if not best in theory.

2) p has a full range of major suit raises. Some are, assuming opp. pass: 1s=2s around 7-10hcp with 3 trump. 3c= around 7-10hcp with 4. Understand many now switch 3c and 3d for a small theory gain.

3 comments:

1) I briefly tried 2/1 with light openings, but switched to forcing for one round (Standard), because of the infrequency of the 2/1 responses which Richard and Ron alluded to. In fact, Richard made the same comment when I first posted what I was doing.

2) I have been playing light openings for a while now (currently a bit lighter than what you are doing now - we open 10 counts with 5 cards, except 5m332, or when they are bad). They have a high upper limit - anything not good enough to bid 2C. I've come to the conclusion that invitational and GF responses should be a little light. The occasional thin game you bid won't kill you, and you will make some of them. These will be more than compensated for by increased accuracy on other auctions. I think you should consider making a 2/1 response with 13 (12) hcp, reducing the 1NT forcing range to 6-12. If you switch to Standard, make 2/1 responses with 11 (10).

As responder, what is your invitational (versus pass/signoff) range after 1M-1N-2x?

3) You might consider Gazzilli after 1M-1N. 1M-1N-2C is 2 way, either 17+ hcp or natural clubs. Other rebids are limited to 16, allowing jumps to be 14-16 with extra playing strength. Responder rebids 2D with 8+, forcing to game, other rebids are weak. I haven't played this, but it seems to me that it may help you with range problems after 1NT. If you are interested, download the AMBRA notes from Dan Neill's site:

or Google rec.games.bridge for Gazzilli:

or start a new topic here. I believe a couple of regular posters play it.

 

Lauria/Versace play 2/1 with 10-21 openers, and play this.

Wow, lot of good info and sites there, ty.

 

Good comments on 2/1 range and therefore 1nt forcing.

If "standard 2/1"=Good 12, then we are off by 1.5 -2pts.

Few questions for all "standard 2/1" forum gurus:

1) Does 2/1 come up that often?

2) Do expert opp. overcalls, etc, reduce your 2/1 frequency even more?

 

For light 2/1 openers:

1) Would guess here, we have even more contested auctions and less 2/1, so great need for full Bergen/ competitive gadgets/toys.

Yes, you will go down once in a while, but not as much as you think.

OTOH, if you don't make GF or invitational bids aggressively playing

light openers, you will miss games. I prefer to be on the side of

thin games rather than missed games. You also get the bonus of

more 2/1 auctions and fewer 1NT forcing auctions.

 

"For light 2/1 openers:

1) Would guess here, we have even more contested auctions and less 2/1, so great need for full Bergen/ competitive gadgets/toys."

 

1) To turn this around, when you play light openings, your opponents have more contested auctions.

2) If you open 1S (say) light, then your opponents may choose to make unsound 2/1 overcalls. Fine. It will sometimes make life tricky for opener's partner, but OTOH the opps will have distorted their overcall structure. A net gain for you, IMO.

3) You need to be able to handle interference, whatever your minimum opening requirements.

What do you do with flat 17s? I think you should play a 14-17 NT, or maybe a 17-19 2♦ opener.

[mike777]

found 17-19 too wide range, so went to Jump rebid =17 Then you can use a simple 2 way checkback/slam try or game force// or complicated Baron.

"found 17-19 too wide range, so went to Jump rebid =17 Then you can use a simple 2 way checkback/slam try or game force// or complicated Baron."

 

Having the 2NT rebid show a 1 point range is inefficient, IMO.

 

If you are going to use both a 2NT rebid and the 2D opener for balanced hands,

why not have 2NT rebid = 17-18, 2D = 19-20, and 2NT = 21-22, taking the 22 hcp balanced hands out of 2C?

What I found is that if you make very light opening bids and heavy 2/1 bids then you can agree to make weak two bids that overlap your 1-bids.

 

The responses are therefore made on the assumption that opener has no more than 5 (or 6 terrible) if he is minimum.

 

1♠ - 2♦ - ?

* 2♠ = Any minimum (at most 6 bad ♠ see above)

2NT = GF 6+♠

3♠ = Balanced range #1

3NT = Balanced range #2

New suit = natural not minimum

 

After 1♠ - 2♦ - 2♠: 2NT and 3♦ are to play, anything else shows extra's and is GF.
