Weekly Hand Analysis - Mark Olsky - November 6, 2023- 1NT Response


 Question:  What is South's next bid and why?


Mark:

I think this is one case where there is a bid that describes the South hand very well, almost perfectly. 3 Hearts! The original 1 spade rebid was shape- showing and, at that point, still unlimited in strength. North is limited, between 6 and 10 points. North could have 4 or 5 hearts, more likely 4. Why can't North have more than 10? Because South is allowed to pass and most often will, North can go to 3NT with  with a mediocre 15. With anything more than 10, North is expected to make a forcing or at least an invitational bid, which 1NT is not. 

  South has denied 4 hearts by bidding 1 spade. Now he shows 3 good hearts and 16 to 18 points. Does that fit? Like a glove! By deduction, North knows that South is short in clubs, having opened 1 diamond, then shown 4 spades and 3 hearts. North can go to 3NT with excellent clubs and 4 poor hearts, pass with a 6 or 7 point minimum or bid 4 hearts with 8 to 10 points and 5 hearts or 4 good ones.
