Solving problems is like learning words when mastering a foreign language. The more words you add to your vocabulary the more comfortable you feel speaking the language. Solving Go problems has nothing to do with sitting behind a Go board in a cold and dark attic, sweating for hours while trying to solve one position. Again it is quite similar to learning foreign words: you go over them, read the translation (solution) and once the whole list is completed you check how many you actually remembered. You repeat this as long as you feel like it.
This set of problems is solved at a glance by dan players, which implies dan players have these patterns permanently stored in their mind readily available when needed. So, if you are a kyu player go over them and learn them and you close some of the gap which separates you from a dan player. Dan players shouldn't skip these problems but should use them to warm up the brain to solve other problems or maybe go over them before playing a Go game, just to get sharp. My estimation is that the problems are around the 9 kyu level. There are two sets of 15 problems each: 1-15 and 16-30. Good luck!
These problems come from a Japanese problem book which features 80 pages with 30 problems each. The problems published here were taken from an advertisement in the Kido monthly magazine February 1998. Once I have more information about the book I will include it here.
