[blml] Two UI/AI cases [SEC=UNOFFICIAL]

Richard Hills:

Case 2 is particularly interesting.

Law 21A states:

"A player has no recourse if he has made a call
on the basis of his own misunderstanding."

And in this auction it is clear that East
carelessly had a misunderstanding that West had
simply accepted East's transfer with a 2H bid,
when West actually super-accepted the transfer
with a 3D bid.

Alain Gottcheiner:

>b) Usually, one wouldn't be allowed to bid
>again after partner's slow bid, if it doesn't
>tell more than one knew on the previous round
>(as after a rejected trial bid). But here,
>East had more information : he knows that his
>partner has made a very encouraging bid on
>the round before, something he didn't know at
>the time, as his use of the "stop" card shows.

Richard Hills:

But this "more information" that East has
gained is _unauthorised_ information, since the
footnote to Law 40E2 states:

"A player is not entitled, during the auction
and play periods, to any aids to his memory,
calculation or technique."

Ergo, under Law 21A and the Law 40E2 footnote,
East must assume that the auction has gone:

WEST      EAST
1NT       2D(1)
2H(2)     4D(3)
4H(4)     ?

(1) Transfer to hearts
(2) Not a super-accept
(3) Splinter bid, slam interest
(4) Not interested in slam

The unauthorised information that East has
received demonstrably suggests bidding slam.
Therefore, if on the above authorised auction
a Pass is a logical alternative for East, then
that Pass is the only legal call that East may
select.
