Straight
Five cards in a row (suit does not matter). For example, you have 89, and the dealer deals 2-T-5-7-J. Your combination is a straight from seven to jack. Here, the ace plays an unusual role, which is allowed to be both the highest card in a poker combination (T-J-Q-K-A) and the lowest (A-2-3-4-5). However, the combination K-A-2-3-4 is NOT a straight.
