The text accompanying R186-R188 is: The proof games R186-R188 have ended in a draw in accordance with the Codex rules. Article 18 says: A position is considered as a draw if it can be proven that an identical position has occurred three times in the proof game combined with the solution. The draw ends the game immediately. This implies that no earlier triple repetition of position can occur.
