Classification of positions
- early opening positions are mostly about occupation of corners and playing approaches and enclosures, until joseki start;
- late opening positions involve occupation of big points and the decision about who will invade first;
- early middle game positions feature invasions and running fights;
- in the late middle game it is very possible for groups to die, since the context is of positions that have become much more solid;
- the early endgame has some qualitative differences (thick plays, slow-moving attacks on weak groups) from the late endgame, in which every play can probably be counted precisely.
This, in contrast, probably does help. For example suppose there is no large framework. Then the game has become a 'game of small groups'. This type of game is normally won by the player with better reading, so it is best avoided (unless you are strong).
