The view of the board can narrow

A full-sized Go board is pretty big. A full 361 points. One of the key skills needed in high quality Go is to keep track of all groups, their interactions and weaknesses. This is a skill that is almost impossible for most kyu players. Especially for fast players!

The lazy habit evolves of a narrowing of vision to localised positions. Often, for example, lazy players tend to automatically respond near to the opponent's last move. They fail to step back to see the whole board. So they fail to evaluate first if they need to respond at all locally, and fail to see if there are bigger moves elsewhere even if a failure to respond is a local compromise.

This is one variety of what I term a gravity of attachment. When attention is automatically drawn to the opponent move, releasing the gravity of that attention can be hard, especially at speed. Playing slowly allows you to pause and step back to see the whole board view of the opponent's move - to get a view of where the move fits into the big picture.

Go is ostensibly a war game. Fast play can make you see just the battles within the war, and miss the global effect of those battles. This is especially the case when a group becomes endangered. Often, the build-up to that precarious status is missed as the eyes invariably only see each battle around the group, and not the effect on the group of those battles.

Key is to let the global war supply the context for local move decision making. Go is a trading game, so scale of trade is key - how can a player know if a trade in one area is the biggest on the board if they do not step back to see the whole board?

When playing slowly, and organising your stones efficiently across the board, you can build such attacks and observe with incredulity how the opponent can so readily miss the creeping endangerment of one of their groups. It can be quite funny to observe as if they were really not looking at what they were doing even though it was staring them in the face.
