For those interested in the latest high tech gadgetry, the following is a link to what Klinger, probably Australia's leading theorist, is currently playing in the Australian National Championships:

Note the 1C opening, which is 11+ .

any details regarding the 2♣ opening?

Haven't run into that before, but I heard that its gaining in popularity

[the hog]

No I haven't - will try to speak to rdk in the next few days; and "yes" it is gaining in popularity here.

The other interesting thing is the systemic differentiation between 5 card and 6 card weak 2 bids.

I'm thinking about trying this structure of 2 bids.
My last structure used multi 2♦, 2♥ 5+sp 5+m, 2♠ 5-5 minors, 2NT 5he, 5m. All weak. But the 5-5 hands never appear so we were giving up a lot of bidding space for free to the opponents.

I'm really interested in the 2♣ opening development if you get some infor please let me know and thanks a lot for the information!

I note that 2H in response to 1NT shows 4+S. That isn't part of Keri as far as I know. Any ideas when he transfers into a 4 card spade suit?

Transfers into 4 card majors are in the Kerri structure with 45 invit and gf hands with both Ms, EricK

[twcho]

As far as I know, Kerri 1NT structure for invitation hand is as follows:
1NT-2C-2D-2H/S: 4+ cards in the M, invite
1NT-2C-2D-3C/D: 6+ cards in the m, invite
1NT-2D-2H-2S: 44 or 54 or 55 in Ms, invite
but for 1NT-2H, responder promises 5+S

About the 2C opening as clubs intermediate or majors 44 weak. What are you going to do if pard opens 2C and you have

KQxx Axx xxxxx x

Pass or 2S? Both can be right or wrong.

Not sure the range on intermediate, but if it is 14-18 or the like, I suspect the bid with this hand might be 2♦. If parrtner has weak majors, he can bids 2♥ and you correct to 2♠. If he has good clubs and intermediate strength I guess he bids something other than 2♥ and if he shows more than minimum intermediate hand you have options of 3♣. 2NT and 3NT I suspect.

I guess at this knowing nothing about these methods. I think tis 2♣ bid would be ilegal in most ACBL event since the anchor suit is unknown (may or may not have clubs). But if you make this intermediate with clubs or weak with 4+ in a major plus clubs, it would be alright. I might be misreading the rules. If memeory serves me well, this has some similariaties to purple 2's is a way, were 2♣ is preempt in ♦ or major two suiter.

Club variant is 10-14. If the 2C opener were diams 10-14 or majors weak, it would be ok.

As it is, it puts responder on a guess when he has a hand similar to what I showed. If resp passes, you might end up playing on the opponents' 9-card fit with nothing on for them... oops. If resp bids, you could be going down in 3C when 2C would have made.

Opps are also under some pressure. That's the good thing of the bid, which otherwise would be unsound.
