As Paul noted above, 2 then 3N is not as unilateral as a direct 3N.

The TD should have explained all options before asking your partner if s/he accepts the bid.

The question was directed at the overwhelming majority of the 1-bidders.

„We just played our overcalls as normal“…and X if you are to strong for an overcall? That is what I (maybe erroneously) call „power double“.

The idea is attractive, but the there is a difference in bidding space. Keeping the structure as over. a 1-level opening you would have to pass 2N. Also you would have to bid 3N over 3m with a classical 2N-overcall. You can‘t use leb because advancers 2N as a negative should be passible. All in all I think there are to much disadvantages, but I admit I haven‘t worked it out.

Then a) what do you bid with a strong notrump overcall? and b) do you play unlimited suit overcalls? You are not old enough to play strong jumps (incl. 2N) and cue:-)

I don‘t play Precision, but open all 11 and most 10 if I have a 5crd M. Were I to play Precision, Ican and would open all hands that I consider to be worth 11. The hand given is a good 9 but not more.

John, I will translate a survival tree from our book. I don’t think that I can copy it in the article. I’ll try and send it to you by private mail if it doesn’t work.

John, I asked the same thing a while ago:

I went for Rosalinds solution and we are quite happy.

1, but with my regular partner I could bid 2. We play that Michaels can be bid on 5-4, so a 1-overcall practically denies 4crd . I would C only when playing ELC.

A big advantage from Raptor is the implications if you don‘t overcall 1N. If you combine Raptor with allowing Michaels over 1m with 5-4 (as Rosalind and I do) your overcalls in a suit never have a higher 4crd with the exception of (1M)-2. Rosalind has a good overview on https://rosalind.home.xs4all.nl/bridge/romi/tegen1x.htm#verdernaraptor (as a survival tree in Dutch).
Either Rosalind or I could turn it into an article (we play more or less the same, but I got the ideas from her). The article should also include follow-ups on double, because X now includes the natural 1N-overcall.

Anything is better then 2 „waiting“. Control showing responses is part of KSU where 2N shows 3 Ks, limiting the wrong-siding problem.

That fits IMO, 3 is a playable spot. 3 (or any other bid) is trying to find the right strain for game and therefore forcing. With 3 nf responder would have to make the decision between possible games.

S is not to blame, but 100% N seems unfair. OTOH if N wants ro play 5 why not bid 3 on the way. As an aside, we play 2 as leb and 2N as 7-10 with denying 4crd M.

As Kit Woolsey often observes, finding the right strain is more important then playing at the right level, especially in a competitive situation. Playing in the wrong strain will often leave you helpless, whereas playing in the right strain gives you a chance even if you have overbid.
