Renowned for his keen intellect and unwavering focus, Dosaku was respected by all who encountered him on the Wei Chi board. However, deep within his heart, he harbored a burning desire to unlock the secrets of the legendary Evanescent Water, a mystical substance said to grant unparalleled clarity of mind and profound insights into the game. Determined to quench his thirst for knowledge, Dosaku embarked on a perilous quest across the treacherous mountains and serene temples of Japan, seeking the elusive Evanescent Water.\n\nAs Dosaku ventured deeper into the heart of Japan, he encountered numerous challenges that tested both his strategic prowess and his character. From ancient riddles guarding hidden passages to formidable opponents who guarded the secrets of the Evanescent Water, every step of Dosaku's journey was filled with excitement and uncertainty. Along the way, Dosaku not only honed his Wei Chi skills but also discovered the true essence of the game—how it mirrored the intricate dance of life itself. Through his unwavering determination and unwavering spirit, Dosaku pushed the boundaries of his own abilities and, in the process, discovered that the true power of Wei Chi lay not in conquering opponents, but in finding harmony within oneself. And in the end, as Dosaku gazed upon the shimmering surface of the Evanescent Water, he realized that the true victory was not in possessing it, but in embracing the journey itself.", "schedule": null, "title": null, "tournament_type": "roundrobin", "handicap": 0, "rules": "nz", "time_per_move": 44226, "time_control_parameters": { "system": "fischer", "time_control": "fischer", "speed": "correspondence", "pause_on_weekends": true, "time_increment": 43200, "initial_time": 129600, "max_time": 259200 }, "is_open": true, "exclude_provisional": true, "group": { "id": 12473, "name": "LittleTongo Club", "summary": "Littleton based GO club.
