No reason to beat around the bush. You need the Franklin’s Official Scrabble Players Dictionary because you're weak. You can't hack in the wild world of gladiatorial wordsmiths. So you cheat. Weak! Weeeak!
If you must use one, at least the Franklin’s Official Scrabble Players Dictionary won't do you wrong. It can resolve 100,000 different words in mere seconds after you punch in what letters you have, and sorts them by score so your feeble mind won't get overloaded by the possibilities.
At least I'll get the satisfaction of knowing you spent $50 on your handicap.
