4x4 problems | 67 |
| You can't play on a 4x4 board, but there are some nice problems. Solving them, you always have to look after the "best result"; that means, a win by two points is better than a win by one, and even a loss by three is better than a loss by two (and therefore the solution). This is a bit unusual, of course, but since there is only a limited number of interesting positions, this is a natural way to increase this number. Please note also that all problems use japanes rules. | |

Xuan Xuan Qijing | 58 |
| This classic Chinese text dates from the fourteenth century, originally published in 1347 by Yan Defu and Yan Tianzhang. The problems take fanciful and historical aspects, with themes relating to stories and events. For example, in the 'Mother of Seven Sons' problem, the seven sons refers to seven white stones at the core of the problem. Known in Japanese as 'Gen Gen Go Kyo.' | |

GuanZiPu | 52 |
| This ancient chinese text contains 1454 challenging problems. It's know as KanZuFu in Japanese. The English translation is roughly 'Manual of Endgame Positions.' However, these aren't endgame problems in the typical sense: they're problems wherein if you could solve one in a game, the game would end, as you'd have just killed a large group or saved some crucial stones. The original book was split into three parts, a start, a middle, and an end. In referencing these problems, I've indicated from which part originated the problem, along with the problem number.

S and S Tesuji Dictionary | 7 |
| This two-volume tesuji dictionary was originally published by Kensaku Segoe and Go Seigen in 1971. For what I think were political reasons, it fell out of print, but has recently been reprinted. It's filled with challenging and fascinating tesujis that look like they've been lifted from games, all organized by general theme. | |
