a trick contains any trump cards, it is won by the highest-value trump card played, not the highest-value card of the suit led. In most games with trumps, one of the four suits is identified as the trump suit. In the simplest case, there is a static trump suit such as the Spade suit in the game Spades, or a dedicated trump suit in the Tarot family (in addition to the other four) is featured. More often, a dynamic trump suit is determined by some means, either randomly by selection of a card as in Oh Hell and the original form of Whist, or decided by the winner or winning bid of an auction as in contract bridge and some forms of Pinochle. In certain games, such as Rowboat and Rage, the trump suit may change during the course of the hand, even from trick to trick. Some psychological variety is added to the game and makes it more difficult to cheat if the trump suit is only chosen after dealing. In some games, in addition to or separately from a trump suit, certain fixed cards are always the highest trumps, e.g. the Jacks in Skat, the Jacks or Jokers in Euchre, and the Rook Bird card in Rook. They are called matadors after the high trumps in Ombre. Matadors either have high point values or special abilities as in Spoil Five where they can revoke legally. Some games have more than one trump suit, such as the quasi-trick game Stortok, in which there are two trumps, with one superseding the other. Other games have no trumps; Hearts for instance has no provision for a trump suit of any kind (the Hearts suit for which the game is named has a different significance). Though trump is part of contract bridge, teams can make bids that do not specify a trump suit, and if that is the winning bid then there is no trump suit for that hand (making such a contract is regarded as harder to accomplish). Declarations In some games such as Piquet, Tarocchini, and Belote, before the taking of tricks commences, players can expose certain cards or melds (combinations) that they possess for bonus points. While this phase may seem to award players for pure chance, those who do declare risk letting their opponents develop strategies to counter the cards that they have revealed. Follow suit In many
