Equip Guding Blade to punish an empty hand — your range-2 Attack deals 2 instead of 1 the moment the target holds no cards. It shines when an opponent has just dumped their hand, or in a thin late game where everyone runs bare. The gold play: strip a target down to zero cards first, then swing for the heavier hit.
Pair it with anything that empties a target's hand — Steal, Dismantle, Zhang Liao (Pilfer), or dragging them into a Duel — then swing for 2. Add an offensive mount or Horsemanship (Ma Chao) to reach a bare-handed seat anywhere on the table.
The easiest answer is to keep at least one card in hand — the +1 evaporates instantly. Draw engines like Sun Quan (Balance) or Zhou Yu (Gallantry) are rarely caught empty, and it is still a plain Attack, so a single saved Defense cancels the whole hit.
