| 51 | #Looking at unsorted test 5, a typical way to solve this would be |
| 52 | #to add an edge Joseki pattern, such as this: |
| 53 | # |
| 54 | #Pattern EJ84 |
| 55 | # |
| 56 | #...... Atari before connecting |
| 57 | #..*... |

| 62 | #------ |
| 63 | # |
| 64 | #:8,J |
| 65 | # |
| 66 | #One should also add a pattern or two for followup. A pattern |
| 67 | #with type J is given a weight of 27 on a 19x19 board, which |
| 68 | #means that it is played automatically unless there is something |
| 69 | #really huge on the board. |
| 70 | # |
| 71 | #Unfortunately, this does not work. The problem is that the values of |
| 72 | #J patterns are scaled. From shapes.c: |
