 6-9  points - dont
10-12 points - dont

               (or 12-14 HCP)

After opening 1 in suit - responder (WITH 4 or more trump fit)
--------------------------------------------------------------
Recount your DPs (5-3-1 instead of 3-2-1). Add a point for each trump
more than the 4.
 0-5  points - dont (unless partner opened at 2 level)
 6-9  points - 2 in openers suit
10-12 points - 3 in openers suit
13-xx points - 4 in openers suit

IMPORTANT NOTE TO THE ABOVE: You can only answer in openers suit if you
have the minimum 4 cards in that suit.

After opening 1 in suit - responder (WITHOUT 4 trump fit)
---------------------------------------------------------
 0-5  points - dont (unless partner opened at 2 level)
 6-9  points - 1 in suit or 1 NT (only if 1 in suit is impossible).
10-12 points - lowest possible new suit (1 if possible but 2 is allowed)
13-xx points - bid new suit. You may jump in new suit if that is long
               enough and you have nothing else playable. Or you may
               wait and do that later if there are more options to try
               out. Your new suit is forcing a round so you are sure to
               get another chance.


After opener has shown NT hand - responder
------------------------------------------
Ignore minor suits from now on. Check if there may be a possibility
for major suit fit. If there is, and you have 8 points then use
Stayman. If not, then count your high-card-points (HCP) ONLY, and
compute what you have together with partner. You will reach a "range"
defined by a lower limit and an upper limit. Do the logical thing after
that (pass, invite or go in game). Remember that one of openers points
is likely to be a DP which is of no value in NT so subtract that point
first.

General notes
-------------
You and partner are always looking for a "fit". A fit is minimum 8
cards in the same suit. 4-4 is good, 5-3 is better. You can therefore
only make a bid in a suit if you have minimum 4 cards in it. Each time
you re-bid a suit you add one card to its length (so second time you
bid hearts you show that you have 5 hearts). New suit from responder is
always "forcing a round", i.e. opener MUST keep the bidding going, new
suit from opener is NOT forcing a round. Responder is always allowed
"simple preference", that NEVER shows extra strength.
