HUSNG refers to Heads‑Up Sit‑and‑Go tournaments—single-table heads‑up events.
Explanation. The acronym combines “Heads‑Up” and “Sit‑and‑Go,” describing a tournament with two players at a table until one wins all chips. HUSNGs are turbo‑paced and demand tight yet aggressive strategy. The term is standard in online micro‑stakes and high‑stakes environments.
