Superb and classic 

Here are some thoughts. In my opinion, we should classify a tactic as an unpinning only when the ULTIMATE goal is simply to get rid of the pinning (because every pinning is dangerous and nobody wants to have it in his own game, right?). However, in situations where the ULTIMATE objective is not just to get rid of the inconvenience of the pinning, the tactical classification should be another one.  In the case of the position presented above, I think that the correct tactical theme is Distraction, which is applied here in order to take the Knight. It is not an Inpinning, achieved through the tactical theme Distraction, but on the contrary, it is a Distraction of a piece that (through a pin) is preventing the capture of a piece, which is the ULTIMATE goal. The definition of Deflection (or Distraction) here at Chess.com is: “Deflection is a tactic that distracts an opponent's piece from doing its job, such as defending an important square, pinning a piece, or blocking an open file or diagonal.”

 What do you think about this? Am I right or wrong? Please, comment!

But, read this: The definition of Deflection (or Inpinning) here at Chess.com is: “Deflection is a tactic that distracts an opponent's piece from doing its job, such as defending an important square, pinning a piece, or blocking an open file or diagonal.”

This is complex

Then the answer should be complex (as in more than one simple component). Your question is a false dichotomy and the two choices are basic tactics whereas the tactical situation is complex. I prefer removing the defender. It captures the complexity of the tactic while avoiding the dichotomy. It's a great example of thought process errors which is at the core of chess. And also the challenge of constantly trying to refute the choices your opponent presents you with by finding a better way (look for a move then look for a better one). I'm convinced it is removing the defender. I'm refuting the options you've given me. Sorry. 😁

No need to apologize. The purpose here is precisely to debate intelligently, which you do very well. I'm actually grateful for your comment, it helped me a lot. I am trying to do a serious study and I need to analyze all points of view to capture the essence and what is most important in different and complex situations.
