I held this hand yesterday: ♠ AQT ♥ A9xx ♦ xx ♣ ATxx MP - First seat, vul. Playing in a intermediate field - I choose to upgrade this hand. The reason for doing it, was that if I opened 1♣, and partner said 1♠, I felt that I would be to strong for a 1NT rebid... Another thing - I don't use Zar points all that much, but when thinking about upgrading/downgrading, I tend to use it to get a "second opinion" - here I have 14+10+6=30zars - which may be 1 point short - but... swap the cards around, and I believe one can construct numerous hands where 1NT is the "obvious" choice. Do you agree? What is your criteria for upgrading a 14hp balanced hand to a 15hp - so you can open a strong 1NT?
