Defense Against Short Minors
There is a good chance RHO has a weak notrump, and if you also have one, it's more likely your hand than theirs (you have position), so start by overcalling 1NT with some weak NT range and a balanced hand. RHO starts 1 short, you would overcall 1NT ...
Bidding Problem in Real Time
That hand should perform very well. It has a 5-card suit and awesome spot-quality. The two T9’s are worth a point and a half. That hand should perform very poorly. It has two very attackable weak suits. Often the best-performing hands are 4333 with all suits stopped. Since the ...
Splitting in 2nd Seat: High or Low?
High if you wouldn't mind partner leading the suit should he ever get the chance, otherwise low.
Settle A Bet
It’s an instructive hand. A little shape goes a long way. Say opener has 14 HCP. If opener is 5332 and responder has that hand, game makes ~ 38%. Make opener unbalanced (not 5332), and percentage making shoots up to 74%. Now make the spade 7 the club 7, so ...
Settle A Bet
I learned that a limit raise asks opener to proceed to game unless he is plainly minimum. I tested a few opener holdings with a double dummy solver which might shed a little light because we're just blindly stumbling around lol. The hand looks to me like a good ...
Quality suit value
I think it is problematic to value most hands, before you know which strain you will be playing. You hold AKQx/QJTx/xxx/xx. Partner opens a 12-14 1NT. If you find an 8+ major fit, you’re close to being a favorite to make 4M. But if you don ...
Mathematic question
Two 50K sims (to see ~ error margin), opener has 5+ spades and 11+ HCP. Overcaller has 11+ HCP. Spade lengths: > 5 0.73% (0.70) =5 4.37 (4.30) =4 14.60 (14.93) =3 29.22 (28.59) =2 30.87 (30.84) =1 16.86 (17.05 ...
Best Use of 2 Diamond Opening
For the HCP ranges specified in the post, the frequencies for 2 are about as follows, for first seat: Flannery (5 or 6 hearts) ~0.9% Weak (6-suiter, max 4M) ~ 1.9% Multi (6-suiters, max 4OM) ~ 3.9% BAL (any 5332, not 5422) 18-19 ~ 3.2% Prec ~ 0.6 ...
After 1!C (P) 1!H (P) 1NT (P), under what conditions should you bid 2!H with a five-card heart suit?
David: Thanks for verifying. I'm getting roughly comparable matchpoint results. For example for AKxxx suit, 1NT wins/ties/loses 44/26/30%, and average IMP win 0.54.
