Defense against a BSC over 1!C
How would this fly? Pass 1 with hearts. X is negative X of hearts. Then transfers: 1 is 5+ spades, 1 is however you play 2, 1NT is natural because it has some situational value, 2 is diamonds ... etc
Defense against a BSC over 1!C
Frances: With those definitions I agree with you. When my pool of 1 overcalls is (1) 5-6 hearts and no other 5-card suits, plus (2) blacks 4-5 long --- it's very close to 50/50 When my pool of 1 overcalls is (1) 5-6 clubs and no other ...
Defense against a BSC over 1!C
And when opposite the 1NT opener, responder sees 5-6 spades in his hand, overcaller will have the 5+ heart holding 89% of the time.
Defense against a BSC over 1!C
Here are some frequencies, I think. For the 1 case, I assumed 1 included all balanced hands (including any 5M332), or was unbalanced with other suits not longer. Tweaking that definition won't make much difference. For the 1NT case, it includes all balanced hands. Overcaller bids 1 ...
Bidding after an artificial raise (Bergen)
Diamonds. Play transfers there. X = diamonds. 3 = unlimited heart support, 3 just competing.
Convention Analysis
I coded (badly) a little utility that kind of did some of the things you're trying to do. I used to include it with a software package that I used to sell. Some information here: I personally used it for a few weeks ...
Alerting in USA?
Previous discussion:
Alerting in USA?
We alert the 'strong notrump' rebid, and also the 2M raise as approx 'either 15-17 with 4 trumps, or unbalanced with 15+ dummy values'. And so also do all other weak notrumpers we encounter.
Weak NT's and Two Way Stayman - using "spare" bids
We play 11-14 with transfers. More than once we've been kind of 'gently scolded' for not playing 'obviously superior' 2-way Stayman. So eventually I just had to find out how eccentric we were. I checked the convention cards for a major international event (sorry do not recall which) for ...
4333 over 1NT
That's a super-sweet 4333 for notrump purposes, with no weak suits, and nice spots. I have that specific holding making 3NT opposite 15-17 5(332) at 76.7%, whereas 4 makes 65.0%. Repeating for a random 4(333), 3NT makes 56.2%, a 20% drop because random ...
