Answers.Text: Maybe I should have mention regarding the big tournaments where the game is being recorded with many cameras and digitally distributed over the web instantly, so the first point is irrelevant. But what if I just keep my own notes whenever I want to and instead of writing down the exact moves I only keep notes of last pawn moved or a capture.. or simply counting the number of moves..! Is that ok? Can I do whatever I want to with that piece of paper that is in front of me or there are rules that you have to or otherwise there is somekind of punishment

Answers.Text: @Lipis In tournaments I believe there are quite strict rules for what you can and can't write on a scoresheet. If I remember correctly GM Wesley So forfeited a game last year for "writing notes" on his scoresheet, which is expressly forbidden I think. Taken to the extreme, you could theoretically write down several possible continuations and save yourself the difficulty of remembering "have I checked that?" - clearly an unfair advantage.

Answers.Text: @JonathanGarber in the 21st century, the chance that "many cameras" fail simultaneously is **much** lower than the chance that the players make a mistake when writing the moves. It is probably more about trust: the scoresheet was written and signed by the players, so they cannot claim later that they do not agree with it.

  A scoresheet allows for a number of different things.
  
  **1. The scoresheet allows reconstruction of the game.**
  
  This is important for several reasons. Imagine that an earthquake occurs and upsets the board. (Or, more prosaically, the table was set up incorrectly and is upset by a light touch.) If there is no record, how would you reconstruct the position?

  Additionally, with modern storage and retrieval abilities, each game is seen as something to learn from. Every single recorded game is one that can teach us new things.

  The two player's scoresheets are the record of the game, and they should "match."
  They prove how the game went, and players' signing them show that they agree on the end result and outcome.
  
  If for some reason, the scoresheets don't match, the game will have to be "reconstructed" by other means, (the position on the board, eyewitness accounts, etc.) Even so, it's likely that one of the scoresheets will "make sense" in this context.
