1. Early position: These are the positions to the left of the blinds, where players must act before most of the other players. This includes the small blind, the big blind, and the first few players to the left of the button. Players in early position have less information about the other players’ hands and may need to play more cautiously.
2. Middle position: These are the positions between the early and late positions. Players in middle position have more information about the other players’ hands than those in early position, but they still must act before the majority of the players.
3. Late position: These are the positions to the right of the button, where players have the most information about the other players’ hands and can use that information to make more informed decisions. These positions include the hijack, cut-off, and button.

It’s important to understand table positions in poker because they can affect the way players make decisions and the strategies they use during a hand. Players in early position may need to play more cautiously because they have less information, while those in late position have more information and can be more aggressive in their betting.
