How does a game of Go look like?
In the beginning of the game the Go board is empty. Then the players put their stones on the board one after the other. The player with black stones makes the first move. An example of the first moves of a game is shown on the diagram.
The game finishes when the players split the board and decide that no more sensible moves are available.

What is needed to play Go?
To play a game of Go one needs a Go board and a set of Go stones. The Go board might be of various sizes. The most important and prestigious Go tournaments are always played on a big board of size 19x19. Beginners usually use a small board of size 9x9. With such a board a game won't take too much time. However, it doesn't make the game less interesting. During big Go events, like European Go Congress, there is always a 9x9 tournament.
Usually a Go board is made of wood. Because the game of Go plays an important role in the culture of the Far East, Go boards are often made of high quality wood. Usually kaya, a type of yew tree, is being used. The Go stones are often made of glass or ceramic. However, the highest quality Go sets include black stones made of slate and white stones made of shell.

Weiqi – the surrounding game
Go was invented in China. In Chinese the name of the game is 围棋 (weiqi) and it means "the surrounding game". In Go, a move consists of putting a stone on any empty intersection of the board. The goal of the players is to surround as big territories with their stones as possible and not to let the opponent do so. It explains why the game is called weiqi. An example of the game is shown on the diagram.
Black surrounded a territory on the right, and white on the left. The one who surrounded more empty intersections (got more points) is a winner. On the diagram black got 35 points and white got 23 points, so black wins.
However, one could ask a question: what if white doesn't agree that the area on the right is black's territory? Can't white play a move in that area? That's true, white can put a stone there. However, it's not clear if the stone will survive. To understand it, we need to learn one more rule of Go. It's a rule of capturing stones.

Capturing stones in the game of Go
An important rule of Go says that when a stone gets closely surrounded by the opponent, it becomes a prisoner and it's taken off of the board. It means that to capture an opponent's stone, one needs to put one's stones on all empty intersections neighbouring that stone (so-called liberties). The same applies to chains of stones. On the diagram there are shown a few chains of black stones.
The marked intersections are their liberties. If white takes all liberties of a chain, the black stones forming that chain will become prisoners.
Knowing the capturing rule, we can understand what happens on the 2nd diagram. White can play on the right side of the board. Then black will try to surround and capture white's stone. If black succeeds, they will defend their territory.
Capturing stones also affects the final score of the game. Every captured stone is counted as one point, just like every empty intersection surrounded by a player. Moreover, according to the rules of Go, if a stone can potentially be captured, a player doesn't necessarily need to actually capture it. At the end of the game they can just claim that the stone is dead. Dead stones are taken off of the board and each of them is counted as one point. If the opponent argues that the stone is not dead, the first player needs to prove and show that they can capture the stone.

How to play Go against stronger opponents?
In many games there is a common issue. What if one player plays better than the other? The game might be boring because the result can be predicted beforehand. However, in Go it doesn't need to be like this. Handicaps can be used to make the game more balanced in a simple way. The players can decide what is a difference in their levels and based on their agreement the weaker player might have a right to play a few moves in the beginning of the game.
In the game the level of players is measured by a Japanese kyu-dan system. This system was invented a few centuries ago and later applied also to martial arts. To have the chances of about 50-50 for winning the game on the 19x19 board, the difference between the players' ranks should equal the number of handicaps in the beginning of the game.
For example, if a 4 dan player plays with a 1 dan player, there should be 3 handicaps. The 1 dan player plays the first three moves in the game and then they continue normally. Like this the game will be balanced.

Komi rule and impossible draws in the Go game
And what about a game between players of the same level? In such a game, the player with black stones has an advantage because of playing the first move. This advantage is balanced by komi - a fixed number of points given to white. It is usually set as 6,5 points. Komi serves also another goal. Because of the half point the game cannot ever end in a draw.

Ko rule - last from the rules of Go
The ko rule is the last of the Go rules. Thanks to the ko rule, every game comes to an end. The rule says that during a game a situation on a Go board cannot be repeated. It would be possible to repeat a situation in a position such as shown on the diagram.
White stone A has only one liberty – at B. If now Black plays at B, the white stone will be taken off of the board. Then the black stone B will have only one liberty - at A. In that situation the ko rule will forbid White to capture the black stone because it would repeat a position on the board.
