Chess Lesson # 56: Obstruction or Interference: the most elegant Chess tactic you will learn

Chess tactics are mandatory if you want to become a good player. In this lesson, you will learn about obstruction (also known as interference). In my opinion, this is one of the most elegant tactical themes out there. Your coach will teach you the pattern and of course help practice it enough for it to stick. In addition, you will see how you can practice obstruction and other tactical themes on your own. If you want to master this, you must practice consistently!

Chess is an intellectual battle where players are exposed to numerous mental processes such as analysis, attention to detail, synthesis, concentration, planning and foresight. Psychological factors are also present on and off the board; playing Chess stimulates our imagination and creativity. Every single move a player makes is the result of a deep analysis based on the elements presented on the battlefield.

Chess in its essence teaches us psychological, sociological and even moral values. In a Chess game, both players start with the same amount of material and time. The fact that the white pieces move first is considered to be practically irrelevant —especially because a player typically plays one game as white and one game as black. Consequently, the final result of the battle solely depends on each player. It doesn’t matter if you win by taking advantage of your opponent’s mistakes or by simply avoiding mistakes yourself. Truth is that Chess is an extremely individual sport and our defeats can only be blamed on ourselves and no one else. And this, in the end, only benefits us because we learn to be and feel responsible for our actions and never come up with excuses to justify ourselves.

We also learn that when it comes to our victories on the board, our opponent’s mistakes play a more significant role than our own skills. Let’s not forget that a Chess game without any mistakes would be a draw. This way, Chess provides us with another valuable life lesson: be humble at all times.
