This might help you understand 9×9 openings.

I should note that a number of go players assert that 9×9 does not have any strategy. I believe that this statement is made in comparison to the highly developed strategical nature of 19×19 go. In order to resolve differences over this issue, I will try to make myself as clear as possible by defining what I mean by strategy: Monteo 2D Good strategy is NOT a deep sequence of future moves that push or attract the opponent to move in your way and end up with your victory ”Chapter 11, The Art of 9×9 Go.

That is a tactic.

9×9 strategy

Strategy is an overall plan on what you want to achieve in the long term and on the whole board. Your strategy comes from your ideas on what you want to get and what to do.

Tactics comes from your experience on how to do what you want do. You can clearly see the opponent’s strategy only after the game ends. That said, it is clear that 9×9 is best characterized by fighting, and I believe that the opening will not generally last more than five moves In other words, the first fight should break out by the sixth move, at the latest.

However, I also believe that there are a number of distinct consistent plans of play that can be implemented. By this, I mean standard light invasions of corner enclosures in which invader is satisfied with destruction of some part of opponent’s territory.

This is probably the most important technique to learn in 9×9. All beginners are familiar with the Invasionbut to progress in 9×9 and later in 19x19you will need to know standard invasion-reduction techniques for other corner enclosures. The big difference will be that, unlike the invasion, the invader is not guaranteed life, but must make light moves, that is, be prepared to make sacrifices.


Switching goals from guaranteed life to sacrificial tactics, gaining something elsewhere, represents a big conceptual breakthrough. White’s move is a typical example. This move is a probeand White’s idea is to either get the corner or compensation elsewhere.

Black has defended his corner, but it looks like White has excellent prospects of the bottom left quarter of the board. Note that Black seems a little overconcentratedthat is, a lot of his territory is occupied by his own stones as opposed to the territory that White intends on making on the left side.

It is important to note that White’s second move is a cross-cut which is one of the fundamental techniques used to implement this strategy. As usual in go, don’t take this sequence in isolation, imagine other stones on top, for example. That was just one of many continuations a large number of variations is typical when a cross-cut occurs. Other possibilities are given on the probe page here. In particular, Black has the line below as an alternative the hane. When one side of the board is open the top in this casethis Black move or one point above or below at a or b is a miai invasion.

This means that if White attacks from the left, Black can live on the right, and vice-versa. Black must be very careful that fighting on the bottom does not spill over to the top, as the urgency of the fight could prevent Black from following through with the miai strategy.

This is a game between professionals Kozue Mukai and Daisuke Murakawa 18 and 12 years old, respectively! White 8 leaves a and b miai, so is an example of such an invasion. For a complete analysis of the game, see the Rob van Zeijst column https: Indeed, if you’ve mostly been playing 19×19 go, you will be surprised, and maybe confused, by the frequent use of contact moves in 9×9.

In this case, Black is using an influence strategy this will be explained below and the idea of the contact move here is to implement this strategy as forcefully as possible. You will note that this violates the principle which says don’t attach when attackingmarking the special nature of 9×9 go. If you are overwhelmed by such contact moves, then I recommend you consider the following technique, which seems to work in many situations.

White’s response is quite flexible as it threatens to pull out the White stone 2 by playing at a or b. So Black, who wants to contain White with a single blow has to contend with some problems of his own. For more about this, see the page explaining why you don’t attach when attacking.

I learned this response by looking at Cho Chikun ‘s 9×9 games on this site http: I do not know the basis for the statement, but could you specify what is incorrect about it?

That way, the page could be improved. Black’s first move leaves the top 9×99 empty, so White implements the miai strategy. Black then takes care that White doesn’t do the same to the bottom.

Which White does anyway! This move is gobban probe and White is ready to sacrifice it. The idea of this move is to leave it as a potential problem technical term is ajithat is, White might later use this stone to make sabaki by either making life or helping neighboring White stones.

Warranty & Support

White does not try to save his stone, which he treats lightly. Attempting to save this stone would be perfect for Black. For example, Black could humor White by letting him live while developing power to later overwhelm the top an application of the principle of leaning attack.

Likewise, Black will not try to capture White’s lone stone outright, as this turns out to govan slow and inefficient. It is true that Black would ensure territory at the bottom, but he would be overconcentrated there, and White will have had time to map out a larger territory more efficiently at the top. For various continuations from this opening position, gobn at the games of Cho Chikun which can be found here http: The same principle applies to 9×9, but on a smaller scale and with an effect that is easier to spot.

I’ve found that if one player has more than two groups on the board, 9x other player should be able to win and probably kill everything.

I modestly yoban this ” Alexander’s Law for 9×9 “. So, split the opponent’s groups enough on 9×9, and you’ll most likely win. See also the page about Splitting Attackit applies even more for 9×9. Responding to a contact move. Three groups can’t win. Four groups can’t win either. Edit page Discuss page.
