[blml] Two UI/AI cases

[Alain Gottcheiner]

Dear blmlists,

Here are two cases from last saturday's tournament.

1.	pass	1C	pass	pass
	1S	1NT	...pass	pass
	?

Would you allow : a) a double  b) a new-suit bid  c) a 2S bid, each time on 
a well-textured
9-count?  In other words, what is suggested by the slow pass ?

	W		E

2.	1NT	p	2D	p
	$$$	p	4D	p
	...4H	p	4S etc.

East put on the table "stop-4D", only to be told that he shan't do that, as 
4D isn't a skip bid : now he realizes partner had bid 3D.

May East bid again, assuming that he had told about everything with his 
"splinter" ?
Would you admit the following arguments ?
a) The slow pass isn't related to West's hand, but to the unusual situation 
created by the alert, and West was wondering what would be ethcical and 
what wouldn't.
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 encouragong bid on the round before, something 
he didn't know at the time, as his use of the "stop" card shows.

Thank you for your advice.

   Alain.
