a score of 21 is achieved. Strategy Basic strategy Basic strategy in tressette revolves around gathering as many Aces as possible because they are worth three times the value of any one face card. As such, players typically attempt to "strip" their opponent of the Three and Two in the suit in which they themselves hold an Ace; at that time, the ace may be played safely and a point scored in their favour. Hence, when holding several lower ranked cards in a suit plus the ace you may play the lower ranked cards in the hope your opponent is forced to play the three or two of the suit allowing you to play the ace. Obviously, holding Ace, Three and Two of a suit (called a "Napolitana", "Napoletana" or a "Napoli") is a particularly powerful holding as it allows you to play the Ace with impunity, careful not to surrender it to an off-suit card. As picking up the last hand garners a point, players try to organize their card play for this purpose near the end of a round. Partner interaction When playing in partnerships, any verbal communication between partners regarding the game is considered cheating, unlike in briscola (oral tradition has it that "tressette was invented by four mutes, briscola was invented by four liars"). There are, however, three conventional signs that can be exchanged between partners: Busso ("Knocking"): The player knocks or raps on the table. This sign can be used only by the first player of the trick. It instructs that player's partner to play the highest-ranked card of the suit being played, in an attempt to win the trick. If the partner does win the trick, that partner is supposed to play any card of the same suit. This strategy allows a player who has a strong card in a suit (i.e. a 2 or 3) to check whether their partner has the other one, without risking to play both cards on the same trick (thus squandering one high-rank card) and keeping the flow of the game under their control. Volo ("Flying"): The player lets the card drop or "fly down" from a few centimeters above the table. This sign signifies that the player has just played their last card of this particular suit. Striscio or Liscio ("Sliding"): The player slides the card across the table before playing it. This sign signifies that the
