Before I became hooked on Sudoku, I was a keen player of the oriental board game Go. Similarities between the two, include for example, the requirement to "calculate" ahead, albeit in differing ways, and the advantage gained by developing overall "sight" of the grid / board so as to minimise the necessity for a brute-force approach. A new web site at http://2.10e.net will include unusual items on Sudoku, and so if anyone has an opinion on whether or not Sudoku is more challenging than Go, I would be interested to hear from you.
