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".

Ronald Kalf's bidding problem: A AQ9874 J74 AK4
3 is AT LEAST invitational. Follow-ups as per Kit are 3=0-1, 3=doubleton, 3=3(4), higher (5)6.
How would you rule?
Michael „It's merely 'extra values in context'“. Exactly, but then I don‘t understand why you want to roll back to 4X. I‘d bid 5 no matter how long pard tanked before doubling.
What killed American Bridge--a Poll from the Year 2040.
1) Hey Buddy, bridge is played in lots of countries, survival is independent of the ACBL. 2) Options 4 and 5 are mutually exclusive (more or less), neither of them will stop the game. 3) Apart from Other, I don‘t like any of the options. So here‘s my ...
Since we are in a game force 2N is stronger then 3N. Give N one more in stead of a (which S can expect) and A in stead of K (although A probably is onsite anyway) and 6 is decent with K sure to be onsite. But ...
Ron the Greatest, I can hardly imagine that a player of your caliber would pass 3.
1) S double shows a trap pass willing to defend 1 (otherwise 2). N should pass. 2) 2 is FG. N should bid 3N with a minimum, 2N is stronger and the correct bid at this point. 3) S expecting 5-4 in the minors makes a slam ...
High level competitive auction- What went wrong?
I voted 5 but don‘t mind pass. Double of 2 would have been my choice too. 4 is … well … uhm.
How would you rule?
Who said that S thought 4 is going down?
Jump cue bid over a 1!D opening bid
Our actual choice, frequency might be too low to keep it though.
