Experienced Scrabble players will often face a dilemma where they have no U tiles, but need to get rid of the Q tile. In this situation the only way to not get stuck with the Q tile until the end of the game is to play words with Q but no U. Remember the words in this list and use them when all U tiles are gone.
The best way to use Q without U words in Scrabble is to play
2 letter words like Qi. Qi is worth 11 points and it is often used in Scrabble tournaments. If you won't play this word it is likely that your opponent will. Strategically it makes sense to play the Q tile as soon as possible.
