Hi all !
Yet another question for a Precision 1D sequence.

Right now we play that the following uncontested sequence shows a natural 6D5oM (or better) by opener, with a maximum of 12 hcp (13+ hcp with 65 or better are opened with conventional "strong" 2-suited openers):

1D...1M
3oM

Sample hand:
QTxxx-void-AKxxxx-xx


The question is:
do you have simple suggestions for responder for slam investigation, enabling him to set trumps, check for side controls and ask keycards ?


Yes I know, I might use "Multireverse" (cheapest reverse, in this case, 2oM), to show several hand types, including this 65, enabling responder to investigate at a lower level, but right now tis would put my pard's memory under too much strain. :(

4♣ sets oM as trump.

That's simple, isn't it? :(

The main problem is that the 1♥ responder could be weak too. Thus 4♦ to play must be in the fraimwork. So an End Signal is difficult to use.

Underneath a suggestion.

3NT= to play
4♣= distribution asking
4♦= to play
4♥= not interested in void or 1/1 side suits and SLam Asking bid ♦
4♠= to play
4NT= not interested in void or 1/1 side suits and SLam Asking bid ♠
5♣= SLab♦ but only interested in AK ♦
5♦= to play
5♥= AK♠?
5♠= AKQ♠? and not forcing-> 5NT= side Queen, 6x=Side K,

4♣ - ?
4♦=void lowest side suit -> 4♥= SLab♦, 4♠= to play, 4NT=SLab♠,5♦=to play
4♥= void highest side suit -> 4♠= to play, 4NT=SLab♦,5♣=SLab♠,5♦=to play
4♠ en higher= 1/1 (will not be a disappointment for partner) and at the same time SLAB answers with ♦ provisionally as trump (if partner bids ♠= to play)

SLab answers:
step1= 1 Ace of 5 (or 4 if a void)
step2= 1 Ace + Trump Queen
step3= 0 or 3 Aces
step 4= 2 Aces
step 5 = 2 Aces + trump Queen

OR if you don't like Slab's then f.e. Spiral Scan (eventually with the restriction that Relayer still has set the trumpsuit with his bid).

====

I hope it answers your request for simplicity? :(
To have a possibility to inform -if important- for the right void is in my opinion a main issue. Reason why such an example scheme is hardly inevitable.
