In bridge there are four suits, and they are ranked: spades (highest), hearts, diamonds and clubs (lowest). The ranking is for bidding purposes only. In the play all suits are equal, unless one suit has been named as trumps, then it beats all the others. Suits are sometimes shown as symbols, or abbreviated: S, H, D, C.
The cards of each suit are ranked from the ace (highest) through the two (lowest). The exact order, using common abbreviations, is: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2. Note that the ace is always high, unlike some card games, such as poker or gin rummy, where it can be low.
