A wet board is a term used in community card poker games to describe a board that provides several opportunities for making a strong poker hand. It’s most often used when the cards are connected or suited and is the opposite of a dry board.
For example, a wet board might be Ks Qs Jc or 9s 8c 6d. With these cards, players can already have two pairs or a straight and have multiple draw opportunities to make a flush or straight, even with a redraw to stronger hands.
