When can a player concede or mutually agree to draw a match?

A player can concede or mutually agree to draw a match at any time until the result slip is filled out. This allows players the flexibility to make decisions based on the unfolding game state, their own assessments of whether they are likely to win the match, or other strategic considerations up until the official match result is recorded.

Once the result slip is filled out, the outcome becomes official and cannot be changed. Therefore, the window for conceding or agreeing to a draw closes at that point. This is why the correct choice highlights the importance of the result slip as the determining factor for when a concession or agreed draw is no longer possible.

Being aware of this timeframe is essential for players to understand their rights and options as the match progresses.
