Me and my magician sister

Chapter 7 8. Backgammon Battle

Zheng Hong was very slow this time, she stared at Ning Jin's formation for a long time.

Ning Jin's array is now in a state full of "forbidden hands", and the sons and sons are related to each other, and it is not the kind with only one handover point.

"I'm screwed." Zheng Hong finally said a word after a long time.

Zheng Hong's eyes are very complicated. There is regret because of the wrong chess just now, a little bit of loss, and a kind of excitement.

After thinking for a long time, Zheng Hong placed a pawn on the side of Ning Jin's formation.

Ning entered the round and played a chess piece, resulting in three connected chess pieces.

Zheng Hong ignored it directly. According to common sense, the situation where three chess pieces are connected together should be stopped immediately, because if not stopped, the three connected chess pieces will become four connected together. At that time there is no chance.It's a pity that this is not a real "backgammon"

However, Zheng Hong ignored it directly and built his own formation on the side.

"Damn..." The pressure in Ning Jin's heart increased again.Zheng Hong suffered a loss before, and now she has mastered the essentials of this game. Is this... the first time playing this game?
This "backgammon" game based on "backgammon" proposed by Ning Jin is completely different from the way of playing backgammon.

The winning requirement of backgammon is simply to connect "five pieces into a line", and then there is no more.The outcome is determined directly.But this game is different. In this game, even if five chess pieces are connected in a line, there is still a follow-up action——remove the chess pieces, and then replace an enemy chess piece.This can lead to continuous outbreaks.

However, it is a probabilistic event that leads to continuous eruptions. When this probabilistic event occurs, another inevitable event will occur.

Assume that, before the chess pieces are collected, the number of chess pieces on both sides on the board is X.The first mover plays a piece, the number of pieces is X+1, and five pieces are taken away, the number of pieces is X+1-5, and another piece is replaced, the number of pieces is x+1-5+1, that is, x -3.Look at the chess pieces of the second player again, the opponent's chess pieces are only deducted by one, which is X-1, and the difference between the chess pieces of both sides is 2.

If the second hand collects some chess pieces first, the number of chess pieces will become X-4, and the difference between chess pieces will become 3, which will cause a greater loss.

Therefore, after collecting the chess pieces, although it is an advantage in terms of victory conditions, it is at a disadvantage on the chessboard.

Zheng Hong is now facing this situation.

Ning Jin continued to set up his formation, and from time to time set up four connected chess pieces, but Zheng Hong didn't bother.

This is also a very deterrent behavior.Because as long as four pieces are placed, it is equivalent to telling the enemy: "I have a chance to take away the pieces at any time." After the enemy knows this, if he continues to stop by the side, then after taking away a connected five pieces, As long as you replace the enemy pieces that are connected with you, you can continue to collect pieces and explode.

Since Zheng Hong took away the first wave of chess pieces just now, which led to her disadvantage on the chessboard, she has been careful with every step she takes.

Ning Jin, who had no pressure from the beginning, is now under a lot of pressure.

Zheng Hong put forward the condition that after closing one wave, immediately close the next few waves, which also gave Ning Jin a headache.

Now Zheng Hong has turned from defense to offense, and she has formed a four-piece chess piece that can be taken away at any time.

"This is forcing me to take away the chess pieces." Ning Jin thought to himself.

That's right, Ning Jin's current situation has improved, but he still can't collect five in one wave. When Ning Jin can collect five in one wave, Zheng Hong has no chance of winning.

Before Ning Jin can defeat Zheng Hong's strength without a wave, forcing Ning Jin to collect the chess pieces in advance is also a good strategy.

Looking at the situation here in Ning Jin, there are obviously many people who can be connected together, but apart from the few chess pieces that Zheng Hong played on the side of Ning Jin's formation at the beginning, Zheng Hong never went to Ning Jin after discovering the pattern. The chess pieces are placed on the edge of the advanced formation.

"How good is she? Can she win now only by the mistakes she made when she didn't know how to play at the beginning?!" Ning Jin bit his lip and fell into a tangle.

"If you want to accept it, you can accept it!" Ning Jin decided, and continued to place his chess pieces.

Why do we have to stand in a passive defensive posture?Obviously, this guy's situation is the same as mine. No matter how you look at it, if she collects chess pieces, she can only collect three waves at most, and I won't lose like that.But if she and I don't accept the chess pieces, I can rely on the large number of forbidden hands created at the beginning to quickly construct a situation where the whole game can be closed in one wave, but Zheng Hong is different, she did not construct in the early stage capable of continuing development.To put it bluntly, this is not a technical reason. I am definitely not as good as her technically. This is the reason why Zheng Hong couldn't play at the beginning.

Ning Jin has already made up his mind, and the only variable factor at present is the chess pieces she replaced after forcing Zheng Hong to take away the chess pieces.

"Patta." The chess piece landed on the cold chessboard.Zheng Hong has a son.

In a wave, a pawn in the center of Ning Jin's formation was replaced.Did not continue.

Ning Jin didn't understand, he was clearly confident, why didn't he know why she didn't continue.

Zheng Hong's face lost the tension just now, and replaced it with the same relaxed expression as when playing other games.

Ning Jin made a move tremblingly.

Zheng Hong accepted a son again.Changed the chess pieces in the center of Ning Jin's formation, but still did not continue.

Looking at the number of pieces on the chessboard, Ning Jin has an absolute advantage in the number of pieces.but……

After one move, Zheng Hong accepted another piece, this time the one replaced was still the central piece of Ning Jin's formation.

"What!!!" Ning Jin couldn't help standing up and shouting.

After working so hard to build the game from the very beginning, he was able to take down five waves at once with confidence, but Zheng Hong made him only able to take down four waves. After four waves were taken away, the advantage became balance of power.In a balanced situation, can Zheng Hong really be defeated?

Zheng Hong kept replacing the chess pieces in the middle of the formation just now, in order to transform her disadvantage into a balance of power, or even an advantage!

Zheng Hong smiled and said, "Stop yelling, little hairy kid, play chess quickly."

The current situation is that Zheng Hong has four Ning Jin's chess pieces in his hand, and he is short of winning by one, while Ning Jin has zero in his hand.

Ning Jin still has no harvest.

Zheng Hong easily clicked on the chessboard, and three consecutive pieces appeared.

"This..." Ning Jin realized that if he didn't accept his son, he would be defeated with a 0:5 ending without any suspense!
"Receive the pieces!" Ning Jin removed a four-in-a-row chess piece, replacing the chess pieces that Zheng Hong played when he didn't know how to play at the beginning, and took away another wave.

In this way, Ning Jin received four waves, and the game became a 4:4 stalemate.
