The first thing you should do on your turn is to look at the chop cards of everyone on the team.
Are there any cards on chop that need to be saved (or played)? If so, do you have to do it, or can someone else do it?
If no-one else can do it, then you need to give the Save Clue (or Play Clue), even if you have a card to play.
If someone else can do it, would it be better for you to save the card, or for them? If they have a card to play and you do not have a card to play, then it is better teamwork for you to save the card.
