One of the key elements in the game is to take the initiative at the right moment. Mostly, this means taking risks.
However, sometimes risks are low, especially when the 3 selected cards offer no particular risk for you.
Example : If the pick is a lobster, a carp and a present, you may normally accept any gift card without hesitating.
At other moments, risks are high and can better be avoided.
Example : If the pick is a piglet, a poison and an umbra, you have a pretty chance that you will get a gift that you don't like.
Observing which cards opponents select and keep for themselves, gives you valuable clues on which goals your opponents have.
Example : If someone keeps a present, he might be particularly interested in presents. If someone gives a dagger away, he might be a conspirator.
Once you have an idea who has which objective, you have extra trumps to hinder your opponents.
Example : You can discard a present or a dagger to avoid that your opponents get those cards.
Sometimes, you might be forced to help an opponent.
Example : If there are 2 accepted daggers and you are not a conspirator, you must help Caligula by discarding a dagger which becomes available. Otherwise, you risk losing the game in favor of the conspirators.
