What it means
Lifting the shin to block a kick so the incoming leg hits bone instead of ribs or thigh. Done properly it hurts the person kicking more than the person blocking.
It is a timing skill rather than a strength one, and it is the difference between sparring being fine and sparring leaving you unable to walk for two days.
Learning to check is also the fastest way to make experienced partners take you seriously, because it is the thing beginners never do.
