The different types of board
The boards can be categorized into several groups. Here are some types of boards for you. Note that these definitions are not exhaustive and that there are many other types of boards. These are only the most common ones.
The boards wet: Would translate as "wet boards" but the use is marginal. Even in French, it is called "wet board". It is a board that offers multiple possibilities (color, straight, full hand, etc.). For example 9-9-J-K-Q with 3 hearts.
The boards dry: On the other hand, it is a dry boards, which offers very few possibilities, for example: 8-8-8-A-2 without possible color.
The paired boards: A paired board is any board that has a pair, such as 2-2-A-K-Q. When you have a color, you want to know if the board is paired or not. If the board is paired, it will be possible for our opponent to fight with a full hand.
