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".

Sorry, this user has no cards yet.
Break In Tempo
Agrre with Lit. unfortunately many ZDs do not understand the difference between a „reasonable bid“ and „no other logical alternative“.
Best use for artificial 2NT opening
2N natural is self preempting.
Another 1!h-1!s question
Weak, 5-8 appr.
Carding Problem
That is the wrong question: You don‘t want to tell your partner what to do. You want to give him the information, that you have a 6th . Probably playing your original 4th best is the way to show count. Your parner must decide if it‘s right to ...
FP situation? If not who should bid 5?
I agree with Richard on X by S, but not Pass by N. With zero defense and 7 cards in pards suits, I‘d bid 5.
Two ways to show an invite with 4crd !s
I know about Revision, but they don‘t differentiate either, it‘s all in 1N. I don‘t remember where I got the idea, not Revision, I‘m sure. The oldest reference in my notes is when we started playing Gazzilli after 1M-1N but not 1-1 in KSU ...
I should downgrade all 4 according to my rules, #1 is 17+. However downgrading produces more stress then upgrading and ATT I would not downgrade #1. Consequently I voted #2, which I rate at 17-.
Best use for artificial 2NT opening
I play 2N as 10-12 with a 6crd m. I don’t know if this is „best“, but it fits nicely in our polish based system. 1-1M;2 and 2 (always 6, not 4M) are more limited and still open light m-hands. If you want to adopt ...
Agreement over (1!S) - 2!H - (2!S) - ?
I play: X=t/o with -tolerance or strong balanced, no stopper, 2N=inv+ with -fit, unfortunately not always able to differentiate between 3/4, 3=Splinter with 4, 4m=fit-jump with 4, 3m= nat, F1. As always, I highly recommend Partnership Bidding at Bridge by Robson and Segal ...
Two ways to show an invite with 4crd !s
BTW, I found a nice idea on how to differentiate between 3crd- and 4crd-raises in an older thread Unfortunately it‘s not very detailed, just the basic idea. Basically it says 1-1;2 is 3crd support and normal raises are 4crd ...
