Where can I find strategy discussion about Dots?
Since the main rule of breathing is different, the players need to achieve completely different goals: In go a group can breath within another group, and the chips may get removed by being killed, while in dots a dot stays forever in game. Both games have the main goal to have the highest possible area, in where some strategies may be similar, but mostly your main goal in dots is to surround enemies dots/area and avoid having your own surrounded. Some of strategies that can be used, are:
Strategy #1: Keeping one dot free space
If the opponent is being surrounded and prefers to build walls, you will be able to catch him by building the perimeter with one dot empty space between every new dot, this helps surrounding faster and is more effective then just trying to catch at the same speed. However you still need to fill every dot you avoid at first to continue surrounding. (x and o are different colors)
x x x x x ...   -&gt; x x x x x
ooooooooooo ... -&gt; ooooooooox (Redirection of o’s)

Strategy #2: Know when you need o give up area
When your enemy has succeeded by occupying one of your zones, you need to know if you can fight for it, or can’t. There are not real parameters you can search for, as it’s very position-depended, but you can look at:

Size of your area
Shape
How much is occupied. (and how is it occupied? Keeping free dots? Any way to break through?)

Strategy #3: Building areas on top of areas
If you have a large area, you can build more small areas onto your large area as in example of green below

Green simply have an area and build all other areas using some of the dots of the main area.
