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".

Paul Maris's bidding problem: KQT942 --- Q8 AK632
The question was directed at the overwhelming majority of the 1-bidders.
Ideas on Raptor
„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“.
Ideas on Raptor
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 ...
Ideas on Raptor
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.
Control-Showing Responses to Strong 2!c Openings: General Thoughts?
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.
Control-Showing Responses to Strong 2!c Openings: General Thoughts?
John, I asked the same thing a while ago: https://bridgewinners.com/article/view/follow-up-to-raptor-1nt-explained/ I went for Rosalinds solution and we are quite happy.
It's your bid
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.
