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".

Strike Gold
IMO this is not an opening bid in a 2/1 context or even my system, where we open 1M withh 11-18. You have to discount Q7 and cannot fully compensate with K9642, so I rate this as a bad 11. In a Precision context I would open 1.
What is the best use for this bid?
„In doubt i like keycard“, the most misused convention in bridge.
What is the best use for this bid?
If you want to bid a marginal slam, you should have a source of tricks and/or no wasted values. I assume that you can find out about wasted values with a self-splinter if responder has a 6-bagger or bidding a second suit with 5-4-3-1 and also can bid a ...
Your Ideal Opening Structure
If you play a good Scrambling Stayman, you have lots of opportunities to find M-partscores.
Your Ideal Opening Structure
What‘s in a name? A rose with any othe would smell as sweet. Quickborn Unassuming Club. Basic ideas from Don Varvel and David Goldfarb called An Unassuming Club. Enhancements by me, Quickborn is the township where I started playing QUC.
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 ...

Regres IS fun to play.
