Save Principle
- Critical and playable cards should never be discarded.
- They can be moved off your partner's chop by giving them a safe action, such as a Referential Play Clue.
Sieve Principle
- Cards that will become useful should be sieved in, while trash cards should not.
- If a trash card is on your partner's chop, let it be discarded before giving them a safe action.
Since Alice's chop is trash, Bob should play p3 and wait for Alice to discard, instead of getting r2 to play.
Good Touch Principle
- When cluing, only cards that will eventually become useful should be touched.
- As a corollary, all clued cards are promised to be useful cards and not trash.
Alice should play slot 5 as g4, since that is the only good touch identity it can be. She does not have Permission to Discard.
- Sometimes, a card cannot be targeted without violating good touch. This is acceptable; it is much more important to save or play the targeted cards.
- However, a clue should be given revealing the trash card as soon as possible.
