• In "Coercion", the color of cards refers to their suit color (red or black), not the card type. You may target any player with a hand card, and the choice of whether to take the revealed hand card or a non-armor equipment is yours. 

• Cheng Yu can take horses and weapons with "Coercion", but he cannot take whatever armor they have.  

• Cheng Yu cannot use "Foresight" if he has more or the same amount of cards in his hands than health.

• "Foresight" lets you replenish your hand at the end of your turn. If your health is low, the number of cards you can draw will be limited to your current health. 

• Cheng Yu excels at controlling and manipulating other players' cards, both in hand and in the equipment area. "Coercion" offers direct disruption and resource stealing, giving Cheng Yu a tactical advantage.

• With "Foresight," Cheng Yu can keep his hand size healthy, ensuring he always has cards to play or defend with. This is especially useful in long games, where card management is crucial.

• Cheng Yu’s abilities allow for diverse strategies. He can play aggressively by stealing key cards or focus on a more defensive approach by maintaining a large hand.

• The power of "Foresight" depends on Cheng Yu’s current health. If he is injured, his ability to replenish his hand diminishes, making him vulnerable in the later stages of the game.

• "Coercion" can only be used once per phase, meaning that while it is impactful, it doesn’t provide constant disruption.

• Cheng Yu relies on his hand size to stay strong, so being repeatedly targeted and losing health can severely weaken his ability to draw cards and maintain momentum.

• Supportive Characters:
  Cheng Yu works well with characters that can help him maintain his health, which in turn strengthens "Foresight." Characters like Hua Tuo, who provide healing, allow Cheng Yu to make the most out of his card-drawing ability.

• Card Revealing Mechanics:
  Cheng Yu can combine well with characters who manipulate the contents of other players’ hands, such as Jiang Wei or Guo Jia. With better knowledge of opponents' cards, Cheng Yu can maximize the value of "Coercion."

• Equipment Synergy:
  Characters who rely heavily on equipment, such as Sun Shangxiang, are prime targets for Cheng Yu’s "Coercion." By targeting their equipment zones, he can strip them of their gear and reduce their effectiveness.

King

• • Cheng Yu is an average King choice. His ability to draw cards with "Foresight" provides him longevity, but his abilities do not directly support loyalists or control rebels. His impact may not be strong enough to protect himself from aggressive rebels.

Loyalist

• • As a loyalist, Cheng Yu can disrupt rebels' plans by stealing key cards, whether from hand or equipment zones. His ability to maintain a full hand allows him to defend his King efficiently.

Rebel

• • Cheng Yu can be a strong rebel due to his ability to target the King directly with "Coercion," taking away key cards or equipment. His constant card advantage through "Foresight" ensures he can remain a threat throughout the game.

Spy

• • Cheng Yu’s card manipulation and self-sustaining hand size make him a strong spy. He can strategically disrupt both sides and adapt his gameplay based on the evolving situation.

Cheng Yu is a flexible general who excels at disrupting opponents' strategies and maintaining card advantage. His "Coercion" lets him control key resources from opponents, while "Foresight" ensures he never runs out of cards. However, his reliance on his health for card draws and his once per turn ability per turn make him vulnerable to aggressive opponents. Cheng Yu performs well in longer games where strategy and resource management are crucial.

Cheng Yu was a key figure during Cao Cao's campaigns, especially known for his strategic brilliance. One of his most famous moments came when Lu Bu launched an attack on Cao Cao's base in Yan Province while Cao Cao was away on a campaign in Xu Zhou. As Lu Bu seized control of much of the region, many officials surrendered, leaving only three counties—Juancheng, Dong'e, and Fan—holding out in defense.

At this critical moment, Cheng Yu was stationed in Juancheng with Cao Cao’s chief strategist, Xun Yu. Realizing that the defense would only succeed if the remaining counties worked together, Xun Yu asked Cheng Yu to take charge of Dong'e County, where his influence as a native could rally support. While Xun Yu oversaw Juancheng’s defenses, Cheng Yu set off for Dong'e, but on the way, he passed through Fan County. There, Lu Bu’s official, Si Yi, was attempting to persuade the local prefect to switch allegiances.

Cheng Yu acted swiftly. He met with the prefect and, through a combination of persuasion and strategic insight, convinced him not only to reject Lu Bu’s offer but to kill Si Yi. After securing Fan County’s loyalty, Cheng Yu continued to Dong'e, where local officials Xue Ti and Zao Zhi had already begun organizing the defense. Cheng Yu further reinforced their efforts by deploying his cavalry to secure Cangting Ford, a key position against Chen Gong.

Thanks to Cheng Yu’s quick thinking and coordination, the three counties were able to hold out against Lu Bu's forces until Cao Cao returned from Xu Province. This victory not only preserved Cao Cao's control of Yan Province but also demonstrated Cheng Yu’s ability to unite factions and defend against overwhelming odds.

This moment in history directly ties into Cheng Yu’s "Coercion" ability in Sanguosha. His use of clever tactics to manipulate opposing forces and protect vital resources mirrors his card-stealing and disruption abilities in the game. Additionally, his "Foresight" ability reflects the calm, calculated planning he displayed, ensuring the long-term defense of Cao Cao’s stronghold.

Later, when famine and repeated losses to Lu Bu wore down Cao Cao’s forces, Cao Cao even considered surrendering to Yuan Shao. It was Cheng Yu who boldly rebuked him, declaring that it would be disgraceful for someone as talented as Cao Cao to submit to a man of inflated reputation. Cheng Yu’s words, combined with his earlier success in defending the region, reinvigorated Cao Cao, convincing him to continue the fight despite overwhelming challenges.
