Using En Passant to gain a mental advantage

Knowing the rule of en passant is the mark of an advanced chess player. Now, I am at a stage between a beginner and an advanced player. I believe that aside from mere rankings, perception is also important in determining how good a chess player is. For this reason, every time I see an "en passant" opportunity in my games I take it. Even if its not the best move in the position. I do this to gain a mental edge over my opponent. It is possible that my opponent has never seen the move, and will proceed to complain in the chat about a glitch. I will then tell him that it's a legal move called "en passant". This will mentally bury my opponent because they will have to accept that they're not as advanced in chess theory as I am.

Now, lets say I didn't take an en passant opportunity. In this case I would be giving away the mental edge to my opponent. The opponent will think that I don't know the rule of "en passant", and will assume that his chess theory is actually more advanced than mine. This will allow him to grow in confidence. I understand that these sort of strategies are unimportant on the higher level, but the purpose of this blog post is to help beginners. 

So to all the beginner players looking to gain a mental advantage, look up en passant. Study the move, apply it, and you will see results.
