Simon, aged 53, spent much of his career as an IT consultant. He has an interest in mathematical three-dimensional puzzles and in recent years he has designed and hand crafted a variety of new puzzles. He has also been playing Go for many years and is a former President of the Central London Go Club. Tournament playing for both Alison and Simon has taken a back seat in recent years to their growing family. They have two children, one cat and four chickens.
