Sure, he says that now.
I started reading another book today - Word Freak: Heartbreak, Triumph, Genius, and Obsession in the World of Competitive Scrabble Players. In the auttor's note at the beginning, I found a rule I had forgotten: If a player uses all seven of their tiles, making a valid word, during a turn, the player gets an bonus of 50 points to their score. I had never known about that rule. And apparently, the rules of tournament Scrabble are 23 pages long. So, it could be interesting to find out more about this aspect of Scrabble.
