A coup[le of times recently I asked about the ditloid 2 H in R , and nobody out there was able to help. You all might like to know that the answer was 2 - Hooker in Rugby. One for the database there.
Perhaps the main reason this answer was not forthcoming earlier owes much to the fact that there is only one hooker in a rugby fifteen, although there would be two involved in a match! ;0)
