Wander through the forests of baseball and soccer with strategists from the Three Kingdoms

Prologue.
In baseball and soccer, the outcome is determined by the coach\'s tactics.
To maximize performance and profits, it is necessary to delight customers and fans with quick information gathering and accurate analysis based on vast data.
The coach, who is responsible for the entire game, must respect the individuality of the players, acknowledge the unique authority of the coaches, and accommodate the demands of the audience, while also considering the strategy for player placement based on the opposing team.
Despite the limited capacity of the coach, the responsibility for poor performance is absolute, so fundamentally, leading players and coaches to victory and success requires deep knowledge of baseball and soccer.
We approach baseball tactics through an understanding of pitching, catching, hitting, defense, and base running, and examine soccer tactics by analyzing the four-back formation and three-back formation.
In the Major League and Premier League, a manager is a condensed version of a strategist.
We wander through the forests of baseball and soccer while reflecting on the fierce lives depicted in the Romance of the Three Kingdoms.
