The challenge this week is as follows (you can download the workbook here):
It is you to start in a game of Scrabble, and your rack of letters (cell Q2) is DGTAROZ.
You are a strong enough player to have deduced a list of all possible words from the Engligh language of two or more letters which can be formed from this rack. Given that list in Q5:Q77, derive a single formula to return the word from that list which returns the highest score when placed on the board (A5:O15).
