Starting in 1968, Hook led the Virgin Islands team, and later the British Virgin Islands team, at numerous Chess Olympiads, mostly playing top board (the last one - he was playing at the age of 83!).

At the Malta Olympiad of 1980, Hook won the gold medal on board 1 for best percentage result of any national team member.

To commemorate this achievement the British Virgin Islands issued multiple stamps in his honor.

[2] During the preliminary rounds of the 1970 Siegen Olympiad, the Virgin Islands were paired with the USA team and Hook faced the legendary Bobby Fischer.

Playing the black pieces, Hook ventured a pet line of the French Defence whereupon an exciting encounter developed, culminating in a stylish rook sacrifice by Fischer.
