Zhou Zhimou is playing chess with his friend Song Bingqi, and this is also Song Bingqi's home, Song Bingqi and Zhou Zhimou are ordinary employees in the same company.

In a few days, there will be personnel changes within the company, so they are discussing how to get themselves promoted, preferably at the same time, but more than ten minutes have passed, and they still haven't been able to come up with a feasible solution, and the two have nothing to say for a while.

Then Song Bingqi proposed to discuss while playing chess, and Zhou Zhimou also agreed.

At this time, Zhou Zhimou casually picked up a chess piece rook in his hand, but he found that the front of the chess piece showed a few Chinese characters, probably the next move, he thought that he had read it wrong, of course, after a few seconds of careful reading, he found that he was not wrong, and then when he put the chess piece rook back in place, it returned to its original appearance.

Zhou Zhimou thought: Is this a special ability? Why not my own special ability? But the special ability of a chess piece?

"Why did you put it back again?" It seems that Song Bingqi is just subconsciously asking, "You still have to think about it before you take the next move." ”

Zhou Zhimou thought that he should be sure whether it was true, so he picked up the specific chess piece rook just now, and the front of the chess piece rook was like an electronic screen showing the instructions just now, Zhou Zhimou knew that the material of this chess piece was wooden, and there was nothing special about it, he felt that this might be the special ability of the chess piece itself, not a special ability that he owned.

Zhou Zhimou wanted to show what he saw to Song Bingqi on the other side, but he found that Song Bingqi didn't notice this at all, and he didn't seem to see anything abnormal, so Zhou Zhimou dispelled such an idea.

"What the hell are you going to do next?" Song Bingqi saw Zhou Zhimou pick up the chess pieces just now, and it seemed that Zhou Zhimou still hadn't thought of a specific move this time, "Your approach will disturb my judgment, you can't pick up the chess pieces and put them back directly, right?" Have you thought about it? ”

"Well, I figured it out, just take this one pawn." Zhou Zhimou said and walked out of the next step according to the instructions of the chess piece rook.

Zhou Zhimou saw that when he put the chess rook back on the chessboard, the chess piece rook would immediately return to its original appearance, and when he picked up the chess piece rook, specific instructions for the next step would appear.

Just as Song Bingqi was about to take the next step, Zhou Zhimou took the opportunity to ask: "Bingqi, this chess is yours, right?" ”

"Yes, I bought it before, it's just a chess game, am I going to borrow it from a neighbor?"

"Have you used both sides?"

"yes, what's wrong?"

"Which side will you have a higher chance of winning?" Zhou Zhimou then asked.

"It's not very good, it's chess skills, right? What does it have to do with which side of the game is played? These are all standard chess pieces, so what difference can they make? ”

Zhou Zhimou understood that Song Bingqi did not find any abnormalities, and naturally he did not see that the special chess piece rook had special abilities.

This time, when Zhou Zhimou picked up the chess piece rook, he saw that the instructions on it had changed, which was obviously different from the instructions just now.

Following the instructions above, Zhou Zhimou took the next step.

"Are you sure that's the way to go?" Song Bingqi looked at the chessboard and said, "Now I am in a favorable situation, but why do you seem to have changed your thinking about playing chess?" ”
