Currently on Sensei's Library there are many problems and exercises on various topics, including life and death, endgame and tesuji. One has to have a reasonable grasp on shape and those more fundamental topics to study josekis effectively. Exercises on josekis themselves, however, seem to be rare.
Although josekis are sets of moves that are kind of fixed and result in a relatively fair result for both players in a local area, Go players learning josekis should also understand the meaning behind the moves:
- Why is this move played this way ?
- What if this move is played here ?
- . . .
Another reason to look beyond the fence is that it is common to have players deviate from the joseki sequence - intentionally or because they do not know it. Sometimes new josekis are created this way.
These exercises discuss how to react when the opponent decides not to play according to the joseki.
