I very rarely guess (I did some guessing for this puzzle, and ended up with a lucky win: https://www.kakuro-online.com/leaders.php?d=21&m=2&y=2020).

But I do use the option that displays all combinations very often, especially for harder puzzles (and obviously not for easy combinations like 29 in 4 or 4 in 2).
