Print the checker-profile reference
One concise sheet for interpreting a group.
One-group reference
Scope: one group of 3–5 cards. Up to two deck identities. C clubs, D diamonds, H hearts, S spades. 7C means 7C@1; 7C@2 is a different physical card. PJ1 and PJ2 are unique printed Jokers.
Run
Same suit, consecutive distinct ranks. Ace can be low or high; never wrap K–A–2. A designated wild rank may be used naturally as its printed face.
Set
Three or four cards of the same rank, all different suits. Two copies of the same suit do not make a set.
Our substitution minimum
At least two cards must be used naturally when any Joker substitutes. This teaching choice is not universal. A printed Joker always substitutes.
Examples: 4H 5H 6H is pure. 4H 6H PJ1 substitutes PJ1 as 5H. 7C 7D 7H is a natural set. KH AH 2H is invalid.
