    A tad unconventional, but who can deny the playing strength of either hand?


    2N 4S; 20-21 balanced // Optional keycard in Ds
    5H 5S; 2 keys, no Q, accepting slam try // King ask
    7N AKQJxx looks like enough

    2NT? South only has 18 HCP.

    This board fits our system like a glove.

    N.       E.       S.        W

                         1Club-small      -

    2Diamond-small    -          2Heart-small     -

    3Diamond-small    -          3Heart-small     -

    4Club-small    -          4Diamond-small     -

    4Spade-small    -          4N.      -

    5Diamond-small    -          5Heart-small     -

    5Spade-small    -          5N.      -

    6Diamond-small    -          7N.      - 

    -         -     

    Where:

    1Club-small - <= 6 L 0 - 37 HCP any shape

    2Diamond-small - <= 8 L 5+Diamond-small. No 4M. If only 5Diamond-small will have 4Club-small.

    2Heart-small - Shape asking relay

    3Diamond-small - 6Diamond-small3Club-small2Heart-small2Spade-small 10 total losers

    3Heart-small - Loser asking relay

    4Club-small - 6 L

    4Diamond-small - CROSS (colour, rank, opposite, same, same)

    4Spade-small - 0 or 3 key card

    4N - CROSS continuation K ask

    5Diamond-small - 0 or 3 K

    5Heart-small - CROSS continuation Q ask

    5Spade-small - 1 Q

    5N  - Q suit ask

    6Diamond-small - QDiamond-small

    7N - to play

     

    After North’s hand shape, 10 total losers, and 6 losers are revealed then from the rule of 18 a Grand Slam appears possible with North having 3 or 4 cards higher than a J from law of total losers. After North shows 3 A and QDiamond-small South can count 16 tricks on top in NT if Diamond-small and Heart-small break or 13 tricks if either Diamond-small or Heart-small breaks so bids 7NT.
