The story behind this beautiful puzzle:
A few weeks ago, former World Champion Vishvanathan Anand was conducting a two-day workshop in Pune, India, which was attended by some of the most talented young players in the world.
To challenge these young IMs and GMs, as well as some of the strongest and experienced GMs in the world (eg, Vidit, Kunte, Puranik) – Anand gave them a puzzle that another former World Champion, Vladimir Kramnik, gave to Anand. The puzzle was composed by a Spanish composer and player, Valentin Marin y Llovet, in 1904.
