After searching for grandmasters opinions in the internet, it became obvious to me that the only efficient way to learn coordinates is to play the game inserting the coordinates or at least solve puzzles inserting them. In other words, the solution is the aways good experience.

I need some chess puzzle app that allows me to solve puzzles by inserting the coordinates. If you can suggest a site that allows the player to play the game inserting coordinates, I would be grateful too. I already know that another site allows this.
