HUD is an on-screen tool showing live stats on opponents during online poker sessions.
Explanation. Short for Heads-Up Display, HUD overlays player tendencies—like VPIP, 3‑bet rate, fold‑to‑c‑bet—onto tables in real time. The name parallels video game HUDs delivering metrics. These tools empower strategic adjustments by revealing opponent patterns quickly. Beginners use HUDs cautiously; intermediates harness them for precise exploitative edges.
