It didn't take long for Tan Xiaotian to come, and under the orders of Old Lady Liu, the child was taken directly to the study, and when he saw Yuan Lang also there, Tan Xiaotian felt very surprised, and was busy greeting the two elders.

"Every day, let me ask you, last night, the big man put a life-and-death problem in the chess room of the Yuelai Inn, did you solve it?" Yuan Lang asked.

"yes, yes." Tan Xiaotian replied - he was studying Wuwu in the morning, and after finishing the homework left by the teacher in the backyard of the inn in the afternoon, he used the wooden Go given to him by Lin Lao Wu to set up chess and study, and he didn't know anything about what was happening outside, as for the dead and alive problem, he didn't take it to heart, in his opinion, the dead and alive question was interesting at best, and there was no need to pay special attention to it.

Old Lady Liu and Yuan Lang exchanged glances - the matter is true, and what Su Quan said is true.

"Every day, now I'll give you a question, you can give it a try and see if you can solve it, okay." Old Lady Liu asked with a smile.

"Okay." Hearing that it was to solve the problem, Tan Xiaotian's eyes lit up, and his two hands subconsciously rubbed together, looking eager to try.

Mrs. Liu's study also has chess sets, although it is not as expensive as the one in the garden pavilion, but it is also a top grade, open the chess book casually, find a problem from it, Yuan Lang grabbed a chess piece and laid out the problem without much effort.

What level of difficulty this question is in "Leisure Collection", Mrs. Liu doesn't know, and Yuan Lang doesn't know, because the author of this chess book can be so stingy that even the most basic hints such as "black first and white death", "robbery and killing" and "public life" are omitted, let alone leave information such as advanced, intermediate, low, etc., and with the chess strength of these two people, they can't solve most of the exercises in it, and naturally they don't have the ability to grade these questions.

It's really a bit funny to say, usually when the teacher asks the students to test the answer, the teacher already knows, or although he doesn't know, he is fully capable of solving it, and this time, the teacher who came out of the question is still full of mud, waiting for the students to guide him - Yuan Lang smiled bitterly and shook his head, his own teacher is really not very qualified.

After finishing the question, Yuan Lang withdrew his hand, "Every day, let's start doing it." He instructed Tan Xiaotian.

"Hmm." Lowering his head, Tan Xiaotian began to review the question, his expression focused and meticulous.

The children were reviewing the problem, and Yuan Lang and Mrs. Liu were also staring at the chessboard, but in addition to thinking about the solution to this life-and-death problem, they were also silently counting in their hearts at the same time, 'one, two, three', and before they could count to four, Tan Xiaotian's right hand had already reached into the chessboard, and then with a snap, he threw a sunspot into the board.

Unraveled so quickly?

Although they had long guessed that this might be the result, it was still a big surprise to the two of them to reach such a speed.

"I'll defend." Yuan Lang picked up a white piece and practiced as Tan Xiaotian's opponent.

Tan Xiaotian took the second way, and Yuan Lang responded to the third way.

Black chess two long - this place Mrs. Liu can also understand, if the black chess is broken in three ways, the white chess two way to eat, the black chess back, although the black chess can eat the three white chess pieces on the right, it is considered to have a considerable gain, but the white chess also lifts out a piece and does work, in terms of life and death problems, this kind of progress is too easy.

If the white chess is connected by two ways, the black chess turns all the way, and the white chess cannot make two eyes, Yuan Lang groaned slightly, and fell all the way to the pull - in his calculations, the two black chess pieces have one eye, and the white chess can stand to eat and live when the black chess is a little bit lower, and the two eyes are live.

However, Tan Xiaotian's next step is to dig in the second road, which is very sharp, and visually gives people a strong sense of impact.

"Is there a magic hand?" Seeing this move, Mrs. Liu asked with a smile with interest - this move is not in addition to his calculations, and his current thinking is still stuck in the small tip of the black chess second path or all the way to the turn.

White plays three ways to eat, black three ways to break, white all the way to mention, black all the way to squeeze in, white all the way to the air, black all the way to chase and play.

Placed here, Yuan Lang did not continue - on the surface, it seems that white has made two eye positions, but when black plays from behind, due to the tightness, white cannot catch the tail of the four sons, so that the eye along the way becomes a false eye, two eyes live, one eye dies, this is the basic rule of Go, so put here, even if the problem has been solved.

"Wonderful, I didn't expect that black chess can still chase and play from behind, if it were me, I am afraid that I would have given up long ago when I couldn't break the eye position on the side when the black chess squeezed all the way." Old Lady Liu stroked his palm and said with a smile - although he was only a child, he had indeed learned a trick from others.

"Hehe, that's good, but have you ever thought about any other ways to kill this question? For example, click directly all the way in? Although the question was set by himself, Yuan Lang also saw it for the first time, and he also made a silent calculation in his heart when Tan Xiaotian solved the problem just now, but his thinking was not the same as Tan Xiaotian's.

"Do you mean that? I've done the math, but it's not true. Stretching out a finger to point to the position in the middle of the white chess space, Tan Xiaotian replied seriously.

"Counted? Is it really not true? Yuan Lang was surprised - how strong is this little guy's calculation power, and how many changes have he calculated in his mind in less than four breaths?

"Hmm." Tan Xiaotian nodded very confidently and replied.

Since the conclusions of the two people are different, then one of them is always wrong, so the chess shape is restored, and the two of them once again simulate attack and defense, but this time it is Yuan Lang who attacks and Tan Xiaotian who defends. The black point is on the one side, the white two are blocked, the left side of the black is standing all the way, the white is on the top of the road, and the black is on the second way.

"Wonderful." Seeing this move, Mrs. Liu praised, and now he found out that the purpose of the black chess point on the road is to tighten the air, so that the white chess cannot be connected to the road, the white chess is mentioned in the second way, and the black chess is eaten all the way, and it has become a false eye here.

"Hehe, point first and then stand, this is one of the common offensive and defensive methods of the side road life and death problem." Yuan Lang smiled and said modestly.

Before the words fell, Tan Xiaotian's hand had already landed on the board, the same mention, but the white chess was not mentioned in the third way, but all the way!

Since white can complete two iron eyes one after the other, black must draw all the way, which is an inevitable hand.

However, the right side of the white chess piece blocked all the way, Tan Xiaotian took a glance first, and although the eye on the left side still owed a hand of chess, the black piece could not be put in, so just the direction of the white chess piece was different, and the result was completely different.
