Using the King - getting him mobile
A recurring trouble for the white player is getting the king mobile, and it’s not just the black warriors who get in his way. One of your problems as white is that your strongest piece starts the game stuck behind your (weaker) warriors, and it will be at least the third move, and more likely the fourth, before you can move him anywhere at all.
The king is usefully out of the starting position on or after the fourth move.
That gives black at least four moves to prepare for your king’s emergence.
You must be prepared to sacrifice a warrior or two in order to get your king to a useful position.
