In chess, direct opposition is the situation occurring when two kings face each other on a rank, with only one one square in between them.

These two were both Kings.  They postured as if there was going to be an epic battle.  Hooves striking the ground, nostrils flared, rearing before they even came together. Hell-bent on showing who was stronger. This is the moment contact was made, they took their time assessing each other with intensity, and as good men do, they practically bowed to one another, ending with a nod of approval.  Each one spinning on their haunches, a shake of the head and back to their mares they went. Recognizing and honoring the strength each possessed.
