Professor of Pharmacy at Hogwarts

"The rule in chess is that white goes first," said Ron, looking across the board.

As soon as he finished speaking, a white pawn moved forward two spaces.

Ron began to direct the black chess to fight.Harry and Hermione silently followed his instructions.

Harry's knees began to shake slightly.

What if we lose?What happens if you lose?Or what happens to the captured pieces?

Can Ron do it?

Harry was suddenly frightened.

"Harry - move four spaces to the right." Ron's voice interrupted his thoughts.

Soon, Harry's questions were answered.

The white queen viciously knocks one of the knights to the floor and drags him off the chessboard.He lay there face down, motionless.

Harry turned pale with fear and looked up at Ron.

Ron was obviously not as calm as he appeared. His forehead was covered with sweat. He tugged on the collar of his robe, as if he wanted to take a breath, and it seemed that it was very hot here.

"I have no choice but to do this," Ron said calmly, "so that you can eat the bishop. Hermione, go ahead."

Hermione and Harry didn't dare to make a sound. They didn't dare to disrupt Ron's thoughts. They were afraid that the slightest sound would affect Ron and cause them to lose, and then be crushed to the ground and dragged out of the chessboard. …

Ron also acted more cautiously.

This was different from the wizard chess he had played before. There were two of his good friends on the chessboard. If he was careless, his two good friends would be eaten.

Look at those captured chess pieces. Ron didn't think Harry and Hermione could resist being crushed by such a big wife.

And because there are captured chess pieces for proofing, many sacrifice and pair tactics cannot be used at all.This caused Ron a lot of trouble.

Every time one of their pieces is captured, the white pieces act ruthlessly and show no mercy.Soon, a large number of lifeless black chess pieces were scattered across the wall.On two occasions, thanks to Ron's timely discovery of Harry and Hermione's critical situation, he found a way to save them.

Ron charged across the board himself, taking almost as many white pieces as they lost black pieces.

"It's almost there," he whispered suddenly, "let me think—let me think—" The White Queen turned her featureless face toward him. "Yes..." Ron whispered, "This is the only way...I have to be eaten."

"No!" Harry and Hermione yelled at the same time.

"This is chess!" Ron snapped. "Some sacrifices always have to be made!"

"I take one step forward and she'll eat me - and you'll checkmate the king, Harry!"

"But--"

"Do you want to stop Quirrell?" Ron's expression suddenly changed. He blushed and yelled at Harry. Sweat dripped down his cheeks and gathered into a small puddle. Flow onto the board.

"Ron—"

"Hurry up, if you don't hurry up, he will already have the Magic Stone!"

Harry didn't hesitate any longer.

"Are you ready?" Ron shouted, his face pale but his expression very determined.

"I'm going - pay attention, act immediately after winning, don't delay here."

He took a step forward, and the White Queen immediately pounced on him.She raised her stone arm and punched Ron hard on the head, causing him to fall to the floor.

Hermione screamed, shouting Ron's name, hoping to see him stand up.But the reality was not what she expected.

Hermione wanted to run over and see Ron, but just as she was about to take a step, she remembered Ron's instructions and could only pull her legs back.

The White Queen dragged Ron aside.It looked like Ron was knocked unconscious.

Trembling, Harry moved three spaces to the left.The White King took off the crown from his head and threw it at Harry's feet.

They won.

The white pieces bowed and stepped back, making way for them to move toward the door smoothly.Harry and Hermione gave Ron one last sad look back before rushing through the door and down the next corridor.

"Will he—"

"He'll be fine," Harry said, trying to convince himself of it.

"What do you think will come next?"

"We've passed Sprout's trap, the devil's net - it must have been Flitwick who enchanted those keys - Professor McGonagall deformed the pieces and brought them to life - and that's what's left Quirrell's magic, and Snape's..."

They came to another door.

"Okay?" Harry asked quietly.

"go in."

Harry pushed the door open.A disgusting stench hit their nostrils, and they had to lift their clothes to cover their noses.Their eyes were also filled with tears. Through their blurred tearful eyes, they saw a giant monster.

However, the giant monster lay motionless on the floor in front of him, unconscious, with a large bloody lump on its head.

"Great, let's go quickly."

Harry breathed a sigh of relief and pulled Hermione towards the door.

He opened the next door. For a moment, the two of them couldn't bear to see what was waiting for them next. However, there was nothing scary here.

There was only one table in the room, with seven bottles of different shapes arranged on it. The third bottle from the left was much smaller than the others, while the sixth bottle was larger than the others.

"Snape's magic," said Harry, "what should we do?"

As soon as the two of them crossed the threshold, a flame rose up behind them and sealed the doorway.The flame was unusual in that it was purple.

At the same time, black flames burst out from the door leading to the front.They're stuck in the middle.

"Look!" Hermione grabbed a roll of parchment lying next to the bottle.Harry stood behind her and read with her:

Danger is ahead, safety is behind.

There are two of us who can help you.

Drink them down, one leads you onward,

The other sends you back to where you came from.

Two contained nettle wine.

Three are killers, waiting in line.

Choose, unless you wish to procrastinate here forever.

We also provide four clues to help you choose:

First, no matter how cunningly the poison hides,

In fact, they all stand on the left of the nettle wine;

Second, the contents of the bottles at the left and right ends are different.

None of them will work for you if you want to move forward;

Third, you’ll notice that the bottles come in all sizes.

There is no death hidden in giants and dwarfs;

Fourth, second from the left and second from the right,

Although they look different, the taste is the same.

"That's great." Hermione breathed a sigh of relief. "It's not magic - it's a reasoning question. I think we have hope."

"Can you figure it out?" Harry asked.

"Give me a minute," Hermione said, picking up the parchment and starting to walk around the table.
