There’s a saying in poker that your hand is only good or bad in relation to what the other player has. This means that you should always have a reason for your actions, whether it’s to call, raise, or check. For example, you should only raise when you have a strong value hand or as a bluff. Otherwise, you should just call to keep the pot size small and avoid being called by your opponents. A high card is used to break ties if no one has a pair or better. This includes two distinct pairs, three of a kind, straight, or flush.
