Hit 7k KGS for the first time today, woo. Now at 13k Tygem but haven't been playing there at all over the last couple of weeks.
In the mail a couple of days ago I got "Get Strong at the Endgame" which appears to be too hard for me at this stage, but I also received "200 Endgame Problems" seems much more accessible. I'm approaching that much like I do GS @ Tesuji- that is, spend a reasonable amount of time trying to find the answer, then trying to understand why my answer is wrong by looking at the answer given

.
I still feel like it's very important to be able to recognise the shapes in which tesuji (endgame tesuji and others) appear, even if you can't read out all possible variations. Endgame tesuji are particularly interesting as sente is such an important consideration there. Once I've worked through "200 Endgame Problems" it might be time to look at the Get Strong book.
Also bought "Step Up To a Higher Level", a problem book with 144 problems in it that I bought because it's supposedly for 7-8k players and it was only ten dollars. The sensei's page on the book mentions that the problems are quite easy- which they were, especially if you read the hints. I worked through the whole book in about an hour and a half, and didn't get too many wrong. I'd say it's about the level of GGPB vol.2, some of it probably being a bit easier than that, and some being a little bit harder, depending on any 'blind spots' you may have. The format is similar to the GGPB series of books, in that it gives problems in sections e.g. opening, life and death, endgame etc. There were a handful of "shape" problems included in there too, which I really enjoy (there are some similar problems in GS @ Tesuji) and they are seemingly under-represented in English problems books. I could be wrong there, maybe in Japanese/Chinese/Korean books the large majority of available books are L&D too rather than other types of problems.
Overall I'd recommended the book, the problems seem to me to be of a good quality, and if you can pick it up cheap like I did then it'd be worth it. I'll go back through and solve it again sometime, maybe upside down and not reading the hints. I think working through a fairly large number of easy problems over an hour or so can be very enjoyable and beneficial at times, especially if you're a bit burnt out on solving just a couple of harder problems.
So now my current study plan is;
- 9-18 l&d problems from 1001 L&D (currently on my first run through of 3- move problems)
- about a dozen of the 1 star problems from GS @ tesuji, once I run out of 1 star problems I'll move on to 2 star
- 2-4 Endgame problems from 200 Endgame Problems.
- Something I forgot to mention, watching lectures from Guo Juans internetgoschool.com site. Planning on watching a lecture every two weeks or so, and re-watching it in the intervening week. Watched two so far, from the 'step by step' course. Most of the information I knew, some was new, but I feel that overall the lectures are helpful, so I'll stick with it for a little while and see how it goes.
