{Here's a grand slam that's easy to bid, but only one other pair did.  First,
Gloria opened 1\S.  This is absolutely correct, a solid opening bid!  She has
six or seven playing tricks, and 2.5 quick tricks (AQ=1.5, A=1), in case she
has to defend.

Brian made a normal 3\D preempt.  At this favorable vulnerability, I might
have tried 4\D, although it might indeed go for a phone number.

Not time to fool around:  I launched into Roman Keycard Blackwood.  Gloria's
5\S response showed two key cards (aces or the \SK), plus the \SQ or extra
length.  Small slams are relatively easy - if you have reasonable values and
controls, just bid it.  The wiggle room of being able to lose a trick usually
gives you a play.

A grand slam is much less flexible.  Before I bid a grand, I want to be able
to either count 13 tricks, or count 12 plus multiple likely opportunities for
a 13th.  We have all the keycards - how to proceed?  One approach is to bid
5NT.  This asks for the cheapest king, but more importantly, it informs
partner we have all the key cards.  That way, partner can jump to the grand
with substantial extra strength or an undisclosed source of tricks.

That would be the wrong approach here.  Start counting:  if hearts run, 6
hearts, 5 spades, and 2 aces is 13.  If hearts take a ruff to set up, declarer
will get 13 by ruffing a diamond.  Yes, this grand is cold when pard has only
5 spades, on 4-x hearts and 3-1 spades.  Bid 7\S, the safest!

Emily might have put us to the test with 5\D.  We had no agreement; but I
would have assumed double=0/3, pass=1/4, bid remaining steps, a treatment
called D0P1:  5\S would again be Gloria's bid - if she were on the same
wavelength.  (I recommend double=even, pass=odd [DEPO], if the opponent bid 5
of our suit or higher, because it always lets us defend, if we wish.)  You
should discuss interference over Blackwood with <i>your</i> partner.}
