▲５三龍 △４一玉 ▲３二金 △同 玉 ▲３三馬 △２一玉 ▲２二歩 △１二玉 ▲２三馬
Why this move works
The answer is ▲５三龍 △４一玉 ▲３二金 △同玉 ▲３三馬 △２一玉 ▲２二歩 △１二玉 ▲２三馬. Drive the king toward the 1-file with dragon, gold, and horse, cap the escape with a pawn, then mate with the horse — a nine-move tsume.
Sacrifice the gold to pull the king to 3二, drive it to 2一 with the horse, seal the retreat with ▲２二歩, and finish with ▲２三馬. The dragon on 5三 rakes the third rank to defend the horse, and the king on 1二 has nothing to capture with. A textbook edge-driving finish.
