Backgammon is easy to play, suitable for all ages, and fun and engaging; It can not only enhance thinking ability and improve intelligence, but also rich in philosophy and help to cultivate self-cultivation and basic resistance. It has been applied on various gaming platforms. Below I will introduce you to a detailed explanation of the opening of the backgammon silver moon, welcome to read.

Bo Chun. A detailed explanation of the opening of the silver moon in backgammon

The picture shows the oblique finger of the silver moon opening, and the defense points below the white chess have a g (this column will only consider the stronger offensive and defensive means, and the white chess is too "absurd" to study the defense points), of which a point is the strongest defense point, and the silver moon opening was also a professional opening, but because later studies showed that the black advantage was still too large, it gradually withdrew from the professional stage.

General Diagram. The 4th hand of white chess is defended at point A of the general map, black 5 is inevitable, white 6 continues to defend, black 7 is a strong hand that is seen, and has done three live two, black 11 is a good hand with both offense and defense (it will be common in the future), and black 13 has become a must-win type. If the following white 14 plays A, black B does chess attack, white 14 is like defending C, and black D is a good move.

Figure A1 white 12th hand change to live three counterattacks, black 13 concise, the following inevitable, after which black go A, B, C win (can not be in B double kill, white can go A counterattack!) );In the picture on the right, white 18 changed to rush four first and then block the left to no avail, if not rush four, black go, d also four or three wins.

Figure A2 in Peng Jianguo's "Opening Guide" Figure 206 points out that black 1 goes white 2, white is 5 defense, and the following to black 27 hands become one son and four kills! I don't think it's as concise as this move).

White's 8th hand changed to F9, strong defense! Black good hand, to black 27 in A, B double kill.

Diagram A3 white 14th hand (Diagram A3) outside stop, black 15 magic hand, below to white 24, black go A, B one son double kill; If the white oak J-16 goes 18 defense, the black goes 21, C, D, how to defend the following white, the black is VCF (more troublesome, swing to see); White 16 goes 17 defense in Figure A5.

Figure A4 points out in Figure A4 that if white 16 goes J8, black can go to the following picture to win, how to block this live three in white, black is vcf win, if you use Milon's program earlier, I don't have to go so much trouble to study each block point again.

Figure A4 complements. White 16th hand K8, black 21 points, below to white 26, black go A, B four three wins; If white 22 blocks above, black has vcf, white 24 if it goes c, black goes d and wins three consecutive attacks.

Figure A5 black 9th hand can also go to i6 (recommended concise move), white 10 go H6 is the strongest, to white 18 after black A a son double kill, white 10 if go B, black go C is the same as Figure A1; In the picture on the right, White 12 takes i8 to the right to stop the live three, and also attacks Black A to kill a son, which shows that black has a variety of ways to win.

According to the position of the two black pieces, Japan divides the opening game of backgammon into three types: Lian, Ma, and Katsura.

Connection: Two black pieces on a line, connected openings. Eight types: Flower Moon, Pu Moon, Silver Moon, Pine Moon, Hill Moon, Oblique Moon, Cloud Moon, and Rain Moon.

Interval: An opening in which two black pieces are on a line, but not connected. Ten types: Rising Star, Cold Star, Loose Star, Venus, Long Star, Stellar, Star, Comet, Wandering Star, Meteor.

Gui: The two black pieces are not on the same line, but they are not connected to each other. Eight types: Creek Moon, Gorge Moon, New Moon, Mountain Moon, Famous Moon, Wanwan Moon, Lan Moon, and Water Moon.

The Japanese gave these openings names that were easy to remember, and gave them the suffix "star" and the suffix "moon" for Lian and Gui. Knowing the meaning of these opening names, it is easier to memorize ......

Backgammon has no history, it must be Chinese. What is the origin? My personal opinion is that they didn't want to make such a hassle, but they have to have a name, right?

So.. There's the flower moon, the cold star or something. It seems that backgammon was invented by the former prince to relieve boredom, right?

After playing a piece, it is called "one step" or "one hand", which is the name of a chess piece; Black makes a move and White makes a move, which is called "turn", which is the name given to each move by both sides.

"Kill" - can be understood as a name for victory. It can be more accurately understood as: after playing a certain move, a clear winning point such as four or three is formed, then this move can be called a killing move.

One or several moves before killing a move can be called "calling a kill" or "doing a kill". But this can generally be understood and used in a broad sense, for example, if your chess strength reaches a certain level, you can see that you can win after n moves and n changes, then you can say that the chess has been killed.

"Star" and "Month" are used in the 26 regular opening names to distinguish between rounds.

The relative position of the first and third hands. In the 26 regular openings, black 1 and black 3 are one or two points apart, when black 1 and black 3 are in the same straight line (horizontal, vertical or diagonal) and two points apart (that is, there is a point between black 1 and black 3, which can be empty or white 2), then the opening name has the word "star", such as Ruixing, cold star, long star, etc. Otherwise, this is not the case, and those with black or day glyphs have "moon" in their names, such as flower moon, puyue, etc.
