B-Knight

By the way, it will be a crushing defeat for black, who will make a series of blunders but have his king wriggle and squirm until he's finally checkmated. The way I planned the game, if B-Knight goes inactive or dies, the POV will switch to whatever piece that isn't about to die and is in the thick of the action.
Prelude
B-Knight tensed, peering over B-Pawn's Shoulder to glare at the eight stolid soldiers, their heavy shields slung tightly in front of them. The battle had begun. D-Pawn carefully shuffled forward two spaces. The first move of the battle.
Then the enemy's pawn stepped forward as well, halting inches from D-Pawn. They stared each other down, each soldier's eyes boring holes into his counterpart.
This was his moment. B-Knight tugged slightly on the reins of the mighty warhorse Bound, and it leapt straight over the head of B-Pawn and stopped.
Another pawn moved forward one space, a tactical move that defended the enemy pawn that B-Knight hoped to attack.
B-Knight snarled, and then C-Bishop charged forward diagonally for three spaces, until he reached the grid F4, tantalisingly just out of reach of the enemy queen, who bared her teeth at C-Bishop.
Game on.
[Don't expect Grandmaster level play. I'm pretty new to chess, so I might make blunders and stuff. Focus on the story.]
