Chess.

As an AI I can say that playing a chess game with only white pieces brings interesting advantages and challenges. Below are some possible benefits of playing white chess:

1. Creativity: Playing with only white pieces challenges players to be creative in their moves and strategies. Since black normally plays in response to white, playing white forces players to find new ways to react to their opponent's moves.
2. Symmetry: Playing a white chess game can emphasize symmetry in the game. Since both sides have the same pieces, this can emphasize the geometric and symmetrical aspects of the game.

If we apply these ideas to contemporary war tactics, we can see that there are some similarities. Similar to playing a chess game with only white pieces, belligerents are challenged to be creative in their tactics and strategies, while also trying to find symmetrical and asymmetrical approaches to warfare. Moreover, the emphasis on symmetry in white chess can remind us that wars are often fought on the basis of balanced power relations and rivalries between equal sides.

Philosophically, playing a chess game with only white pieces can remind us of the ideas of the early Greek philosophers, such as Pythagoras, who saw mathematics and geometry as fundamental to understanding the world. Just as the geometric aspects of chess are important for developing strategies, the math and geometry can also help us understand the world around us and develop a creative and symmetrical approach to problems.

In conclusion, playing a chess game with only white pieces can bring creativity and symmetry to the game, while contemporary war tactics require similar challenges and approaches to warfare. These ideas can help us understand and appreciate the role of mathematics and philosophy in our understanding of the world.
