Handling variance in poker, particularly during a losing streak, involves maintaining emotional discipline and sticking to a solid strategy. It’s crucial to focus on making correct decisions rather than short-term results, keeping perspective that variance is inherent in the game. Managing your bankroll conservatively can help endure downswings, and taking breaks can prevent frustration from affecting your play. Reviewing your hands and learning from mistakes can reinforce confidence in your strategy, helping you navigate tough periods calmly.
