Same Direction Cannons
Basic Formation: 1. C2=5 C8=5.
As both Cannons are move from the same side of the board, it is called the Same Direction Cannons. If Red started with C8=5, Black would counter with C2=5 for the Same Direction Cannons. Technically, the correct word should be ‘ipsilateral’ to describe the movement of the Cannons.
It is one of the oldest opening systems in Xiangqi and is still seen in major tournaments.
The development of the Chariots, Horses, and Pawns will determine which variation is played. Generally speaking, there are three major opening lines:
a) Same Direction Cannons: Filed Chariot vs. Ranked Chariot ( 1. C2=5 C8=5 2. H2+3 H8+7, 3. R1=2 R9+1)
Same Direction Cannons: Ranked Chariot vs. Field Chariot ( 1. C2=5 C8=5 2. H2+3 H8+7 3. R1+1 R9=8), and
Same Direction Cannons: Filed Chariot vs. Deferred Chariot.
In the last opening system, Black chooses to develop his Chariot later on in the game and will usually play H2+3 or P7+1 ( 1. C2=5 C8=5 2. H2+3 H8+7 3. R1=2 H2+3/P7+1).

Diagram 3 Same Direction Cannons: Filed Chariot vs. Deferred Chariot (P7+1)
Diagram 4 Same Direction Cannons: Filed Chariot vs. Deferred Chariot (H2+3)
Opposite Direction Cannons
Basic formation: 1. C2=5 C2=5.
As both Cannons moved are from opposite sides of the board, this opening system is called the Opposite Direction Cannons. As with the Same Direction Cannons, if Red started with C8=5, Black will counter with C8=5 for the opening system to be called the Opposite Direction Cannons. Technically speaking, ‘contralateral’ might be a better description.
There are two major variations: the Major Variation of the Opposite Direction Cannons and the Minor Variation.
Unfortunately, the Major Variation of the Opposite Direction Cannons has fundamental flaws and has gradually become out of use and seldom seen in actual tournaments. Instead, if Black chooses to play the Opposite Direction Cannons, he will usually choose to defer playing C2=5 much later. Such a strategy is called the Deferred Opposite Direction Cannons. It usually results from Black playing the Left Cannon Blockade or the Left 3 Step Tiger before countering with the Opposite Direction Cannons.

This position is reached by playing:
1. C2=5 C2=5 2. H2+3 H8+9
Diagram 6 Opposite Direction Cannons, Minor Variation
This position is reached by playing:
1. C2=5 C2=5 2. H2+3 H8+7
Diagram 7 Central Cannon vs. Left Cannon Blockade with Deferred Opposite Direction Cannons
This position is reached by playing:
1. C2=5 H8+7 2. H2+3 R9=8
3. R1=2 C8+4 4. P3+1 C2=5
Diagram 8 Central Cannon vs. Left 3 Step Tiger with Deferred Opposite Direction Cannons
The position is reached by playing:
1. C2=5 H8+7 2. H2+3 R9=8
3. P7+1 C8=9 4. H8+7 C2=5
Central Cannon vs. Screen Horse Defense
Since Wang Zaiyue published the Plum Flower Manual, the Central Cannon vs. Screen Horse Defense has become the most commonly seen opening system in all major tournaments today. There are simply too many variations that can be played. For interested readers, the author has written a short article introducing the evolution of the opening system over the past few centuries. Please refer to the following link.
However, the basic formation for Black’s Screen Horse Defense is the development of both Horses as Proper Horses with the Cannons in their original positions. The resultant formation is a screen.
The Screen Horse Defense is very versatile and has been proven over time to be a viable counter against the Central Cannon. The various opening lines that can be seen nowadays are drastically different from Wang’s initial variations. Red’s Central Cannon has also been pushed to the limits, and many new ways have been developed to attack the Screen Horse Defense.
Generally speaking, Red can choose to attack the central file by linking his Horses on the central file. Red can also choose to play the 56 Cannons, the 57 Cannons, 58 Cannons, or 59 Cannons.
The development of the Horses for both colors will also depend on the Pawns that have been advanced.
It is impossible to include all the various commonly seen variations in this short article.
Diagram 9 Central Cannon vs. Screen Horse Defense. Basic Formation
Red will start with C2=5 followed by H2+3. Black will usually play H8+7 and eventually develop the other Horse as H2+3. However, it is very common for Black to develop the Chariots, Pawns, Cannons, et cetera before developing the second Horse as a Proper Horse. The versatility of Black’s counter is what makes it such a powerful weapon.
Central Cannon vs. Sandwiched Horse Defense
Although the Sandwiched Horse Defense had already been seen in the ancient manuals, Grandmaster Hu Ronghua is accredited with making it a popular and viable counter against the Central Cannon.
The basic formation of the Sandwiched Horse Defense is the development of both Horses as Proper Horses AND developing one of the Cannons as a Palcorner Cannon. Because the Palcorner Cannon is placed between the Proper Horses, it has been called the Sandwiched Horse Defense as if it was sandwiched between the Horses. This name was initially given in a wordlist provided by the Asian Xiangqi Federation in the 1980s.
Diagram 10 Central Cannon vs. Sandwiched Horse Defense
As with the Screen Horse Defense, the Sandwiched Horse Defense has evolved into a highly complex defense system of its own. There are many similarities with the Screen Horse Defense. The development of the Pawns (3rd or 7th Pawn), the Chariots, the Elephants, and the Advisors will determine the final variation that is played.
Central Cannon vs. Single Horse Defense
As its name implies, the Single Horse Defense has only one Horse that protects the Central Pawn. Thus, Black develops one Horse as a Proper Horse and the other as an Edge Horse.
As the Central Pawn has only one Horse protecting it, the central file is relatively weak in the Single Horse Defense. Although it is considered an orthodox opening, it is not commonly seen as a direct counter to the Central Cannon. Instead, a similar formation is frequently seen in the Pawn Opening with Central Cannon Variation vs. Thundering Defense with Left Elephant Variation.
The Single Horse Defense has been around for centuries, and the evolution of this opening system has suggested that Red will fare better by attacking with a Filed Chariot. It has also been proven that Black will be fare better if he develops his Chariot as a Ranked Chariot.
Diagram 11 Central Cannon with Filed Chariot vs. Single Horse Defense with Ranked Chariot
Central Cannon vs. Left 3 Step Tiger
The 3 Step Tiger is divided into the Left 3 Step Tiger and the Right 3 Step Tiger. While the former is considered to be orthodox, the latter is considered to be unorthodox.
The Left 3 Step Tiger is sometimes seen in tournaments. Black starts to counter with H8+7, C8=9, followed by R9=8, where the pieces from one flank are developed. Black will usually continue with the Deferred Opposite Direction Cannons or formations similar to the Screen Horse Defense.
Diagram 12 Central Cannon vs. Left 3 Step Tiger
Central Cannon vs. Left Cannon Blockade
The Left Cannon Blockade starts with Black playing H8+7, R9=8, followed by C8+4 as the first three moves against Red’s Central Cannon. From there on, Black can choose to play the Deferred Opposite Direction Cannons or formations similar to the Screen Horse Defense.
Black starts his counter aggressively and applies pressure to Red’s right flank, but this is done at the expense of inadequate development of Black’s right flank.
Diagram 13 Central Cannon vs. Left Cannon Blockade
Central Cannon vs. Mandarin Duck Cannons
The Mandarin Duck Cannons is an unorthodox but surprisingly popular counter to the Central Cannon. It is also occasionally seen in significant tournaments, which is quite impressive. There are many other Chinese names to the Mandarin Duck Cannons, but the most commonly used term is such.
The defining characteristic of the Mandarin Duck Cannons is Black using the Chariot to protect the Cannon with R9+2, which is an awkward way of doing so. The other Cannon would have retreated to the throat rank where Black will start his counterattack very early in the game.
There are two main variations to the Mandarin Duck Cannons counter: the 3rd Pawn Advancement and the 7th Pawn Advancement variations.
Diagram 14 Central Cannon vs. Mandarin Duck Cannons (7th Pawn Variation)
The Mandarin Duck Cannons demands a lot from Black as Black’s position can become very congested. If Black does not play his position very well, he can self-destruct very quickly. l
Central Cannon vs. Turtle Back Cannons
The Turtle Back Cannons was invented by the late Manchurian Xiangqi expert, Ba Jiren, who wrote about this counter in the Anti-Plum Flower Manual.
Diagram 15 Central Cannon vs. Turtle Back Cannons
This position is reached after playing:
1. C2=5 H8+7 2. H2+3 R9+1 3. R1=2 C8-1
Red will often choose to attack by playing P3+1, P5+1, or P7+1. Black will then move the Cannon to the relevant attack to start countering immediately.
Central Cannon vs. Tandem Cannon Defense
This unorthodox counter starts with playing C8+1 to protect the Central Pawn. C2=8 is the next move to prevent Red from developing his right Chariot as a Filed Chariot. It first appeared in the ancient manual Strategic Considerations.
Black aims to concentrate his forces on one flank very early for a quick counter.
Diagram 16 Central Cannon vs. Tandem Cannon Defense
Red starts the game with P7+1 or P3+1, but P7+1 is mainly seen in competition. The author regrets that the current ECCO system defines the Pawn Opening as P3+1 and the ECCO classification, thus names the various opening variations in a manner that is opposite to the literature seen.
It is a very versatile opening which allows Red to adjust his opening formation as he wants. Red can continue with the Central Cannon, the Elephant Opening, or the Horse Opening.
Black usually counters with the Thundering Cannon or the Pawn Opening for the Pawn vs. Pawn Opening. Less commonly seen counters include moving an Elephant to the central file, developing one of the Horses, or even using the Golden Hooked Cannons.
The Pawn Opening has been quickly become very popular in competition nowadays and is the second most commonly seen Red opening. The main reason is its versatility and the ability to keep the opponent from guessing. Players with a strong midgame and endgame would often lead the game into less common lines or variations.
The following diagrams show some of the most commonly Pawn Opening and Counters.

Diagram 18 Pawn vs. Pawn
Diagram 19 Pawn vs. Elephant
Elephant Opening and Horse Opening
The Elephant Opening and the Horse Opening are similar to the Pawn Opening, whereby Red keeps his options open and only reveals his plan a few moves later.
By default, Red will play E3+5 for the Elephant Opening, and Black will counter with the Left Central Cannon, Cross Palace Cannon, Palcorner Cannon, Pawn Opening, et cetera. Often, the opening will be led away from the beaten path.
As for the Horse Opening, Red will play either H2+3 or H8+7 as his first move. Red can adopt various variations of the Central Cannon, Screen Horse Defense, Sandwiched Horse Defense or Single Horse Defense, et cetera.

Other Unorthodox Openings
There are other unorthodox openings like the Advisor Opening (A4+5/A6+5), Chariot Opening (R1+1/R9+1), Edge Pawn Opening (P1+1/P9+1, as mentioned above), Riverbank Cannon Opening (C8+2/C2+2) et cetera.
This short article is meant to introduce the basic opening systems in Xiangqi that are commonly seen. It is by no means exhaustive. Some opening systems have been studied so deeply that the opening line is defined only after the 10th or even 15th move.
