Body: <p>I am wondering if there are any statistics on rejected draw offers (say of GM games). Namely, what are the following percentages of the following results when a draw offer is declined:</p>
  
  <ol>
  <li>The side that offered the draw offer wins.</li>
  <li>The side that declined the draw offer wins.</li>
  <li>The game ended as a draw.</li>
  </ol>
  
  <p>Technically there is a fourth result: the game has not ended yet at this moment. We may ignore this case for simplicity. For game with multiple draw offers, we may only consider the first draw offer.</p>
  
  <p>By the way, this statistics may be useful in determining whether it is wiser to accept most draw offers or not. If the side that offers the draw wins more than the side that declines the draw offer, it might be wiser to accept a draw offer in an even game. (Here I am assuming that almost all GM's will not offer a draw if he/she has a clear disadvantage.)</p>

  1. The side that offered the draw offer wins.
  2. The side that declined the draw offer wins.
  3. The game ended as a draw.

  The simplest answer is "No" because draw offers are not retained. By that I mean that although the players may record draw offers on their scoresheets, that information is thrown away when the games are transcribed and saved.
  
  In all events where norms are possible the organizer has to send the records of the games in electronic (pgn) format to FIDE. When the game inputters input a game they do this by using a program like Chessbase or Scid vs PC which gives the ability to enter a game using the mouse. Many of you will be familiar with doing this with your own games.
  
  Adding extra information like draw offers is very time consuming and not a requirement. Hence no game inputters do this. The information is lost.
