Mike Lawrences advocates using the double of a splinter as calling for teh lead of the lowest unbid suit. I saw someone else use a different meaning, asking for teh higher unbid suit.

 

 

I'll take a guess -

 

I think XX indicates first round control of hearts (since pard has a stiff), or it might mean 1st or 2nd round control of Clubs (the lowest unbid suit - if opps are using that agreement. It may be a control in dealers suit)

It shows Slam interest.

 

4S is the weakest, denies slam interest.

 

As for Pass, hmm.

Pass also probably shows slam interest, because declarer could bid 4S.

I don't think declarer wants to play in 4 Hearts Doubled.

Pass is probably slam interest, with no Heart control, but why not cue bid or Blackwood? Is declarer worried about trump quality? Or has another open suit? In that case responder should cue bid a minor suit ace, or at least the one matching the X.

XX from opener shows 1st round control and slam interest (unless opps double ask for a lead in a specific minor).

 

Pass from opener show slam interest, but denies 1st round control. XX by responder will then show a void.

 

4♠ from opener denies slam interest.
