A straight in poker is five sequential cards in order, non-suited. A full house in poker is when you hold both a pair and three of a kind in your hand. For example, suppose you playing at 888 NJ and you have JhTh. If the flop comes QsKdAs, you have flopped a straight. If you hold the same cards and the board comes JsJdTc, you have flopped a full house. A suited straight is what is known as a straight flush and is so powerful that it can only lose to a royal flush, which is a straight flush with cards ranked from ten to ace.
