Live betting hockey offers edges that don't exist pregame if you can read game flow and momentum shifts. Waiting for information - which team has legs, which goalie looks sharp, how refs are calling the game - provides advantages worth the increased vig on live lines.

Reading Momentum

Hockey momentum shifts visibly. When a team dominates possession for 5+ minutes without scoring, the live total often hasn't adjusted despite likelihood of imminent goals. I bet overs when possession dominance hasn't translated to goals yet but clearly will.
