How To Play Go - Part 3- A Two-Player Go Fight Over Cocaine Supply Centers
If you are not already familiar with traditional Go, reading through this example will give you a sense of how a territory struggle between two players might unfold. If you are already familiar with Go, the part to pay attention to in this example is toward the end when the Kiss The Ring rule is applied.
Let’s start with the situation shown in Diagram 32 in which it is Red’s turn. Notice how the Red cell only has one liberty left. Red wants to save this cell so it must place another cell there and make a larger group to gain more liberties.
Remember: When your cell has all its liberties occupied by opponents, your cell is captured and must be removed. However, when you place a cell next to another one of your cells, they become one living group.
Red places a cell on the empty intersection immediately to the east (R1 in Diagram 33).
Now, the two Red cells form one living group and have three liberties. These are shown by the three hollow red circles in Diagram 33. In order to capture them, Blue has to surround the now growing group of Red cells.
Blue decides to place their next cell on the intersection immediately north of where Red had just placed (B1 in Diagram 34).
Now it is Red’s turn. Red decides to expand the group, making it harder to surround. Red places a cell on the intersection immediately to the east (R2 in Diagram 35) thereby creating 3 new liberties.
Blue decides to partially block a potential southward expansion of the Red group by placing cell B2 (Diagram 36).
Red extends northward with R3 (Diagram 37).
Blue cuts off Red’s northward extension by placing cell at B3 (Diagram 38).
Red decides to put some pressure on Blue with R4 (Diagram 39).
Notice now that one of Blue’s cells (B3) is suddenly in danger as it has only two liberties. Blue also now has a two-cell group that is potentially threatened with two liberties remaining.
Now Blue must consider defensive measures but at the same time wants to put pressure on Red.
Blue decides to aggressively press the attack on Red’s main group with cell placement B4 (Diagram 40). So as not to clutter the diagram too much, I have not included the small hollow circles to indicate threatened liberties. By now I’m sure you are familiar enough to spot the liberties yourself.
Red sees that its larger group is potentially in trouble, but also sees that it can put considerable immediate pressure on B3 and potential pressure on B4 by cell placement R5 (Diagram 41).
Blue defends against the immediate threat with B5. This saves cell B3 from immediate capture. (Diagram 42)
Red places R6, thereby threatening B4 with imminent capture (Diagram 43).
In desperation, Blue plays B6 (Diagram 44).
While Blue's move keeps the B4 cell alive for the moment, it is a mistake because now both B4 and B6 are doomed!
Red places cell R7 (Diagram 45).
At this point, Blue should abandon B4 and B6 since they cannot be saved, but the Blue player is a novice and mistakenly deploys cell B7 into a certain death situation (Diagram 46). What a waste!
Red places cell R8 (Diagram 47) onto the last remaining liberty for those three Blue cells. Now the three Blue cells must be removed.
The three Blue cells are removed from the board (Diagram 48) and are set aside, out of play for the remainder of the game.
Red now has the option of invoking Kiss The Ring. Red decides to use Kiss The Ring on the Blue cell that was immediately south of R7. Red places an unpurchased cell on that intersection (see Red cell designated KTR in Diagram 48).
Beware of Having a False Eye
In having placed the Red KTR cell where it did, Red has created a structure with one eye and one false eye (Diagram 49).
A false eye is an internal liberty that can still be captured because it involves a cell that is not part of the chain. In Diagram 49, the R8 cell could still be captured.
Now let’s pretend that Blue’s next cell deployment is B8 (Diagram 50).
Red responds with R9 (also shown in Diagram 50), and in so doing, Red has turned the false eye into a real eye. Now the overall structure of cells that Red has created has two eyes. With these two eyes, this structure cannot be surrounded and the Red cells that comprise it shall survive the rest of the game.
So, that was a Go fight between two players. Earlier you saw how it can look with up to six players placing cells on the board.
Now, to play GoCaine, you'll need to learn a few rules about the economic aspect of the game. The reason you are trying to conquer these territories is so that you can build an expansive network of supply centers, transit zones, and lucrative retail markets. Now that you know the basic rules of Go, and the special rules we've introduced for multiplayer Go, go to the Rules menu or watch the instructional videos and in no time you'll be ready to play! Cheers!
