Coping with interference over the ace ask

 

This is a simple no-memory approach.  Doubles are always ignored.

            Pass means the teller would have made a lesser bid.

            Double shows that bid.

            Bids higher than that are unaltered.

 

Over a cheap next-step interference, double says "that's my bid" (1 ace or 3 or 4 less the Q) and opener asks as usual.  Higher bids are as they would be without the interference.

 

Over a 2-step interference, double says "that's my bid" (2 aces) and higher bids are the usual.  Pass says "I would have bid lower than that" (1 ace or 3/4-Q) and asker doubles ("that's my bid") to ask for 1 or 3, or as normal bids the one below the trump suit to ask for 4.

 

Over a 3-step interference, there is now no room to distinguish the Queen.  Assume your side has it.  As before pass means "I would have bid less than that (1 or 2 aces), double says "that's my bid" (3 aces) and higher bids are as normal.  But now there is a special bid - if teller makes the pass to show 1 or 2 aces, asker can double to ask whether 1 or 2.  Teller now signs off with 1, or shows kings with 2 aces. 

 

If there is an interfering bid immediately after the teller’s reply :

            Pass means the asker would have continued by making a lesser bid       

            Double means the asker would have made that bid, which must therefore be an ask

            Higher bids are as normal

Teller then makes the logical pass, double or response to the further ask.

 

Coping with interference over the king ask

 

This is the same simple no-memory approach.  Doubles are always ignored.

            Pass means the teller would have made a lesser bid.

            Double shows that bid.

            Bids higher than that are unaltered except that if you have 2 kings to show, including a bypassed king, you bid the grand.

 

Over a cheap next-step interference, double says "that's my bid" to show the cheapest king.  Other kings, or no kings, are shown as usual as if there was no interference.

 

Over a 2-step interference, double says "that's my bid" that shows that king, but denies the one bypassed.  The other king, or no kings, are shown as usual as if there was no interference.

 

Over a 3-step interference, double shows that king and no lower.

 

Over any interference that bypasses a king, teller bids the grand with any 2 kings including the bypassed king.  If neither of his kings is bypassed, he shows the cheapest in the normal way.

 

If there is an interfering bid immediately after the teller’s reply

            Pass means the asker would have continued by making a lesser bid.  As this would have been a further king ask, it asks teller to bid the grand if he has that king.       

            Double means the asker would have made that bid, which must therefore be asking teller to bid the grand with that king.

            Higher bids are as normal

 

If the interference bid jumps to a level higher that your small slam, then double unless you were going to bid the grand anyway.
