This will be idealized...
- 1♦ - natural, nonforcing (yes this is the non-natural system thread)
- 1♠ - natural forcing (what more natural)
- 3♠ - 30 to 32 Zar points four card support (2NT is stronger ♠ raise)
- 3NT - Serious slam try
- 4♣ - first or second round ♣ control *
- 4♦ - first ir second round ♦ control (not stiff or void in partners suit)
- 4♥ - Last Train, I can count 5!D tricks with the 4♦ cue-bid, last train neither denies nor promises a ♥ stopper, but shows a hand willing to try for slam (in light of the ♦ king in partners hand.
- 4NT - over 4♥ east knows that when he bids 4NT (kantar rkc) his partner will bid 6♣ (1 or 3 keycards, club void) or 5NT (2 keycards, "unknown void"). 4NT however does promise a heart control here or 5NT Lackwood would be used.
- 5NT - two keycards and an "unknown void"
- 6♥ - jospehine. 6♣ would ask for void, and responder knows the response will be 6♠ to show ♣ void. And 6♦ might be misunderstood as option to play ♦'s. 6♥ can not be natural and must be looking for the missing ♠Queen
- 6♠ - I don't have the ♠ queen
- 7♦ - pass is also an option, but here, 7♦ is clearly possible option, see logic below
Why 7
♦ on Kx in a suit partner never rebid?
Partner has
♣ void, clear. So
♦ is his longest suit, minimum of five. Partner showed 30 to 32 Zar points with his 3
♠ bid, and his 4
♥ last train showed the diamond cue-bid improved his very narrowly defined hand for the 3
♠ bid. He would not be excited about about his hand if he had something like S-Kxxx H-QJxx D-Axxxx C-void even after the 4
♦ cue and he would return to 4
♠ and probably would have with Kxxx QJxx AQxxx void as well. So the 4
♦ had to solify his suit as a source of tricks. If he had has AQxxx in diamonds, you will need !Ds to split or partner to have the !DT as well, but odds are he will be 4-3-6-0 with AQ or 4450 with AQJxx.
But seriously, probably just play 6
♠ like everyone else.
