Here is the personaliy of the week.Several years ago, I read the book "Chappelli", an autobiography of Ian Chappell (A really good read for cricket fans) where he eulogised "X". Later I dug up more info and watched several videos of this amazing cricketer whose career was unfortunately cut short by Politics.

Clue # 1 : Rated as one of the best cricketers the world has ever produced, he unfortunately played just 4 international test matches and zero one-day matches.

clue # 2 : A criticism often levelled at X is that at times he found the game of cricket too easy and became bored.

clue # 3 : Endowed with immense natural talent, he has scored scored a century before lunch nine times in his career!

clue # 4 : His opening partnership with Gordon Greenidge in English county cricket is one of the best opening pairs the world has ever seen.

clue # 5 : His most memorable moment came in Australia in the early 70's when he scored 300+ runs in a single day against the likes of Dennis Lillee, Graham McKenzie.

clue # 6 : Sir Donald Bradman, described X as “the world’s best-ever right-handed opener”.

clue # 7 : Needless to say, Bradman chose X as one of the openers in his best ever team, published after his death.

Who is X ?
