NT Range announcement
A book came out a few years ago about a method for evaluating NT hands. Banzai was in the title. A partner and I have adopted Banzai evaluation and this is on our convention card. However it means that sometimes we open 1NT with an 11 or 15 point hand, pass with a 12 point hand and sometimes bid one of a suit on a balanced hand with 14 points even though our stated range is 12-14 points. Someone suggested we should announce it as 11-15 points. On another occasion when we announced it as nominally 12-14 points and explained our upgrade/downgrade method they said that announcing it as nominally 12-14 is not necessary as everyone upgrades/downgrades in one way or another. I always use Banzai to evaluate my NT bids of which most partners aren't aware. In the interests of full disclosure what should we do?
For those interested, Banzai evaluation of balanced hands can be summarised as:
Count Ace as 5 points, King as 4, Queen as 3, Jack as 2 and 10 as 1. Holding a 5 card suit add 2 to the total. To make life easier for us we take two thirds of the resulting total to give an equivalent Milton work point count. It may sound complicated but a little practice makes this an automatic and easy calculation - and it works to a large extent. With 10 or 16 points we don't open 1NT even if the Banzai equivalent comes within the 12-14 range.
