While I am at it - the promised whammy for Ben. (This is a message I posted over at Yahoo,) Some things have been causing me problems with No Trump bids, especially since playing Weak NT. I am asking this rather as a standard question, not as "partnership agreement". 1. Opening NT - Over Opp's interference. a. If Opp's interfere, whether it be a double or a suit, should ALL conventions be OFF? b. If Opp's bid 2C and you were planning to bid Stayman, do you double to imply Stayman? c. If you have points, 2 4-card major suits but no stoppers in Opp's suit, what do you bid? If you doubled Opp's suit, would the NT opener know it was for take-out? ======================================== 2. Stayman/Transfers: a. I have heard of different types of Stayman: Forcing/non forcing, Puppet? Could someone explain them? b. If you are playing transfers, is a 2S bid always a minor transfer? To what suit? Or is it Stayman? Gosh, I am mixing things up now, I think. c. When people talk about "Jacoby" are they talking about just plain transfers or is it more? ======================================== 3. Overcalling NT: a. Is it always so, that when P bids 1NT, as an overcall, ALL conventions are ON? Happened to me last week and I didn't "recognize" 2C as Stayman ::D ======================================== 4. Doubling NT, a. If P doubles Opp's NT is this always for penalties?(not counting NT defence conventions where a double means something in particular.) b. So, if you have a balanced hand, are weak, but no long suit, it is ok to pass? c. If you have a weak hand and a long suit , you should take out the double? BTW One fantastic new feature at BBO is that little box you get when you right click onto someone's name. With so many people and so many quirks it is great to be able to include individual bidding agreements(quirks). This includes some agreements to the above questions. Orla
