Our 2 opening is 12-16 with 6+ clubs or 54M. If opponents overcall directly, what would you play? New suits NF at the 2-level and forcing at the 3-level, DBL for takeout, and 2NT invitational? How about over a takeout double?

Here's a hand (A): you have Jxxx Kxxx QTxx A, it goes 2-(2). Your call?

(B) You deal yourself JTxx Kx A9 AQJ9x and it goes 2-(X)-p-(2). Your call?

(C) You deal yourself KTxx QTx K AKJTx and it goes 2-(2)-X. Your call?

(D) You hold KQJ9x Txx Axxx Q. Partner deals and opens 2 and RHO rudely intervenes with 3. Your call? (Bonus question: if you choose 3 and partner bids 4, is it forcing?)

1. Pass
2. I would have opened 1N. If I opened 2, I pass now
3.3
4.3. Yes it is forcing and I would bid 5 or 4 50-50. 4 is best, if we have a CLEAR agreement that it is Choice of Games.

By the way, I like to play 2NT as Lebensol over 2M overcalls.

1. pass
2. same as the_clown
3. 2.5 depending on the phase of the moon... probably 2
4. 3, 4 is forcing (don't try to get out of a misfit at the 4-level) and I'll probably bid 4 over that, there's little risk of going overboard.

Funny, I thought hand (A) was between double and 2NT.

If you are going with the transfer option then you can keep the same structure as much as possible. So, after a 2 overcall, double can be 4+ spades and so on. If you did that then you get: A) X (4+ spades); B) Pass; C) 3 (max with 4 spades); D1) 3 (natural, system off); D2) yes, forcing. Of course you could also choose to defend on Hand A - that's more of a judgement call than system though. I think 2NT should tend to deny 4 spades here, unless you decide to play it as artificial anyway.

NFB and lebensohl, if we follow our agreements it should look like;

2C-(2D)-??

X = show cards at least 2D
2M = NF
2NT = INV or GF with clubs
3C = to compete
3D = H inv or better
3H = S inv or better
3S = please bid 3NT
3NT half a stop

Using 2Nt might wrongside a possible 3Nt, but im rightsiding many other contracts.
------------------------------
2C-(2H)--??

X = show cards at least 2H
2S = NF
2Nt = to drop in 3m or GF club raise.
3C = Diamonds INV or better
3D = stayman.. neg X
3H = S inv or better
3S = please bid 3Nt
3NT half a stop.

Its annoying but we dont have all club raise.

2C--(2S)--??
X = cards at least 2S
2NT to drop somewhere or GF club raise
3C = D inv or better
3D = H inv or better
3H = stayman
3S= please bid 3NT
3NT half a stop.
----------------------------------------
2C--(X)---???

XX = diamonds
2D = H
2H = S
2S = inv values bal or with some clubs

not too sure about 3 level bids however but they should be transfers INV or better (great suits).

Pass and X show close to 10 pts.
pass and bid is takeout

Bottom line is we never let that difference of opinion interfere with anything."

Thanks, but I wouldn't call what you posted Lebensohl, looks more like Transfer Lebensohl or Rubensohl. ;)

We use something very similar to this. The 2M is nf and 2N is a puppet, 3m is constructive and dbl is invitational+ without a great fit for partner's minor. I think all of this is strong. By giving up penalty doubles we free up 2N and get to handle awkward hands of GI+ strength.


We don't use 3-level transfers, opting instead for fit showing bids. We also use 2N to compete in a lower ranking suit and GF with six in a higher ranking suit. I think either approach is fine.

Our Precision-like 2 opening denies a biddable 4-cd major.

We use conditional transfers to show a good 5-cd or better major. Opener accepts with 2+ cards in the major, otherwise rebids 3 with minimum and 2NT with maximum. This works well for us.


Responder passes the example hand, no problem.

That's nice but you're in the wrong thread. ;) Perhaps look for one of the threads straube started?
