Strategy for this list
B is worth 3 in Scrabble and starts a moderate share of the dictionary (~4,000 words). High-value B-openers include BAZAAR, BEZEL, BLITZ and BLAZE — B lets you score for both the leading tile and the vowel that follows. In Wordle, B-starters cluster around BREAD, BRAIN, BLACK and BROWN — testing a B in position 1 confirms both the letter and one of the most common English opening consonant clusters (BR-, BL-). The two-letter B-words (BA, BE, BI, BO, BY) are all valid and BY at 7 points is a top-value two-letter play.
