At this moment, a deep voice from a middle-aged man came to his ear: "Advance the pawn."
Grandfather raised his head with some puzzlement and saw the middle-aged man. He shook his head: "Advance the pawn? Won't the opponent's knight come over easily?"
"His knight won't dare to move."
"Huh? Why not?"
"If he moves the knight, the center will be open, and your rook can move straight ahead... within five moves, you can checkmate him." The middle-aged man smiled and spoke confidently.
Grandfather's face showed doubt, and opposite him, Jing Chaoyi also showed a confused expression. The middle-aged man rambled on, yet she couldn't see it.
The middle-aged man laughed: "One should observe a game silently... apologies."
Grandfather shook his head and stood up directly: "Come on, sit down, let's see how you checkmate him."
The middle-aged man didn't decline and straightforwardly sat down in front of Jing Chaoyi, then just as he had said earlier, he advanced a pawn.
