Some questions about Mo Ngai Tze's go game:
1. Was it actually possible to solve the game using conventional go tactics, or was Hui Juk's way (blind luck) really the only way to solve it? Deun Yu and Deun Yin Hing were among the finest go gamers in the world at the time, and neither one had an answer for it. If the two Deuns couldn't handle the game through conventional tactics, then maybe nobody could.
2. Why did Dr. Sit die from attempting to solve the game? People either win or lose games, but generally don't die just from playing them.
