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".

A matter of style ?
A matter of system, not style. Not my choice though, but then I don‘t open 1M with a 5crd M either.
Your preferred defenses vs. 1NT
It is:-)
Defense agains natural 2!c
I too like MH‘s answer and have already propos3d to play it. I wouldn‘t use 3 to show reds because opps have a no-risk X to show . How about 3 reds non-forcing and 4 +M FG?
Your preferred defenses vs. 1NT
I play Woolsey now, but would prefer X in direct position as opening bid strength with a good suit to lead. Partner can pass with 8+ hcp and stoppers in at least 2 suits, bid 2 as p/c or bid own suit. Others Multy-Landy. I‘ve forgotten the ...
Your preferred defenses vs. 1NT
What do you mean by penalty? Partner is supposed to pass >90% of the time?
