This technique is typically used when a player wants to go heads-up with a weaker player who has already entered the pot. By raising, the player discourages other players from calling, effectively isolating the weaker opponent. The goal is to exploit the opponent’s weaknesses in a heads-up situation, giving the player better chances of winning the hand.
Isolate Example
For example, if a loose player limps into the pot and another player raises to isolate, the raiser aims to face only the limper, avoiding stronger players.
