Poker players only have four moves to work with, and all of these will represent what their hands are. It also helps you avoid challenging situations that may require you to put more equity in the game. However, if you’re only going to call a mid-range hand, it’ll save you more chips. Remember, once you run out of chips, you’re out of the game (tournaments and sit and go’s) or need to reload (cash games or rebuy tournaments). You have to consider many things when playing, but protecting your chips should always be your priority. If you want to play your hands, but you’re having doubts about it, a flat call will allow you to stay in the game without putting too much equity. However, this rule doesn’t always apply to everyone, especially if your hand isn’t that strong. If you’re only starting to understand poker, one of the first things you should learn is to play aggressively.
