Before the third and fourth are played, players run a pre-round, declaring whether they have matching cards (Pares). In this pre-round, the players announce by turns 'Pares sí' (they have matching cards) or 'Pares no' (they don't have matching cards). Having matching cards means that two or more of the cards in their hands have the same face value. If none of the players in a team can play, the whole round is skipped and the other team will score the round in the scoring phase. If none of the four players has Pares, the whole round is skipped altogether.
