Craig Williams
The author is an Ivy League graduate and a Big-4 Process Improvement consultant who was actually horrible at sudoku for an unmentionable period of time. However, he is tenacious about mental challenges, asks questions, records answers, and looks for what is missing (or not adequately explained) in everything he does at work and at play.
So clearly, sudoku was a great place to start.
He felt strongly that the joy of solving the more difficult puzzles was compromised by a lack of instructions...
