BO gives a player a consonant and a vowel, and unusually the same vowel often returns in the third position. That repetition is what makes BO harder to narrow than the size of the field alone would allow, since a large part of the 5 letter words starting with BO carry a doubled O.
O leads the third position, ahead of R and N. Books, Boost, Bored and Bonds cover both patterns, so a guess that avoids the second O removes more candidates here than testing any other letter.
There are 173 five letter words starting with BO. Board, Bound, Bonus, Boxes and Bones are the strongest Wordle guesses because none of them repeat a letter. BOO and BOR hold the deepest runs, so test O and R in the third slot first.
