Wow! I think I actually just had a small ‘aha’ moment.
Okay, I was thinking up until now, of the Queen or Jack 1st or 1st and 2nd as a flip of the hundreds place digit (representing suit) to the tens place digit.
I thought if queen first then:
Queen, Suit, Number
4, suit (base 8), 0-9 (base 10)
If queen first AND second:
Queen Suit Queen (but didn’t understand how this worked)
but if it is queen first and queen second it is actually:
Queen, Queen Suit
(in other words, 4,4,Suit)
So to show Qx4x vs QxQx is the difference between:
4, Suit, 4
4, 4, Suit
So if 4/8 is first you know the first card is one of those combinations!!
And if in the tens place, the numbers are 0, 1, 2, 3, 5, 6, 7, 9 it is a suit pair value, and if 4 or 8 then it is a face card, with the suit in the ones place!
I see now that it’s not a trade but the use of the word “supersede” is very literal here.
Is what I’m reiterating as you meant it?
