44 points for one word is amazing! How did you manage that?
Triple word score and high points letters are key!
I've heard one strategy is to start building words around the bonus tiles and then wait till you have just the right letters to get a high score. Would you agree?
That is one of the strategies that I try.  It is hard to beat my husband!
Do you play together? Have you ever played the app game based on Scrabble called "Words with Friends", that could give you some practice time.
We do play together.  I have played words with friends and I believe it helped me improve at Scrabble.
Back in 2018 Scrabbles official dictionary added 300 new words. Do you ever have arguments over whether a word is allowed?
Oh, yes!  A lot of times my husband says my words are not "words", but they always are!
How do you sort that otu? Do you use the official dictionary or just argue until one gives in?
We use the official dictionary online!
