Hnefatafl - the Viking Game

How Hnefatafl pieces capture...part 3

Article text
In hnefatafl, a piece can also be captured by being trapped between one of the refuge squares (four corners and centre) and an enemy piece. In this diagram, the white warrior is moving so as to trap the black one between it and the corner refuge square, and the black one is captured and removed. So, it is NOT SAFE to put a single warrior right next to the corner square! The same goes for the centre (throne) square.
