I tackle LinkedIn Crossclimb #906 in three passes — middles first, ordering second, combo ends last. This 4-letter board runs LOVE → … → FEST with combo clue "A compound word for a gathering where people praise and appreciate each other.".
Middle phase: I work clues in board order — "Peaceful bird on a United Nations postage stamp" → DOVE; "Amount of medicine" → DOSE; "Something a fashion model "strikes"" → POSE; "Put online, like a LinkedIn update" → POST; "Irritating child or insect" → PEST.
Ordering phase: the valid middle chain is DOVE → DOSE → POSE → POST → PEST. This permutation is the only valid one-letter chain for these answers.
I verify LOVE to DOVE — L→D at the first letter (LOVE → DOVE).
I verify DOVE to DOSE — V→S at the third letter (DOVE → DOSE).
I verify DOSE to POSE — D→P at the first letter (DOSE → POSE).
I verify POSE to POST — E→T at the fourth letter (POSE → POST).
I verify POST to PEST — O→E at the second letter (POST → PEST).
I verify PEST to FEST — P→F at the first letter (PEST → FEST).
Finished chain: LOVE → DOVE → DOSE → POSE → POST → PEST → FEST. Combo ends LOVE + FEST clicked once ordering locked. Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
