about me

I am a retired IT product manager and live near Hamburg, Germany. I Played bridge in the Netherlands seriously 72-78, the last 3 seasons in the 2nd highest team league. BTW the NBB is the second largest bridge association in the world! Systems were KS, Roman Club, Precision, our homegrown LOB (M-openings 8-13 and a 14+ Precision like 1C), Romex, then back to KSU again. Moved to Germany because of a lovely women and stopped playing bridge until retirement at 60. Now playing German standard Forum D and first KSU then homegrown system based upon An Unassuming Club (courtesy of Don Varvel and David Goldfarb) with my regular partner. As you can see from the list, my motto is "Bridge is a bidders game".

Your Ideal Opening Structure
I‘m perfectly happy with my QUC based upon Polish Club, but with WNT. Further: 2 never with 4M, 1 always unbalanced and possibly longer , 2/ transfers with weak two or strong 2-suiter, 2 both minors either subminimum opening or strong, 2N subminimum m-1-suiter ...
Can this sequence exist?
If opps are silent we play 2, but if they bid, I give pard a choice between 3 on a possible 3-3-fit or 4. I call that inconsistent.
Can this sequence exist?
Of course I also assume W to have 3crd , nevertheless the bidding is inconsistent with whatever W has.
What is minimum requirement for Maxi Unusual 2NT hand?
I abstained, because from his comments in the first post as well as from this poll I have the impression that Yu Chang doesn‘t really know what he is playing. Options 3-5 describe continuous range and ask for the border line between minimum and maximum. This is not the ...
Your Ideal Opening Structure
Regres IS fun to play.
ATB - Bidding after Unusual 2NT
For the discussion it doesn‘t matter if you base your two ranges on points or LTC, what matters is that there ARE two ranges plus an inbetween range where you would not bid 2N. If that is the case IMO you have to treat it as a maxi-2N once ...
ATB - Bidding after Unusual 2NT
OP: „The agreement for value of 2NT is mini-maxi, either a weak hand (8-11) or a very good hand (15+).“ Above: „yes, I do play continuous range“. I am confused! Are there two Yu Chang here?
ATB - Bidding after Unusual 2NT
IMO playing mini-maxi you MUST bid if you are maxi, otherwise you might as well play continuous range.
BW 2/1: Opener's 3NT Rebid
The problem is, that after 3N in this style, you still don‘t know what strain. If you want to cater for responders possible 5-5, 5/6m is still in the picture. Probably best to play Mulberry over 3N.

I prefer irony, sarcasm is wasted on me.
