Microsoft Word vs Scrabble Champions

The 2018 Scrabble World Championship is over. How does the Microsoft Word spell check fare against the Scrabble champs?

Microsoft Word has slightly different dictionaries for many English language variations (US, UK, Australian etc).  Word’s English dictionaries different from the official Scrabble dictionary.

Among the words in the final rounds were:

• Groutier
• Zonular
• Phenolic
• Maledict

MS Word recognizes the middle two words but not ‘Groutier’ (means sullen, sulky or cross).

Maledict (utter a curse) is known to the US English dictionary for Word but not the UK English or Australia dictionaries.
