Great, thank you! : )
I guess, I sometimes take my approach to hardwire shapes into my brain (by repeating the same problems over and over again) a step too far and forget that you can solve quite a bunch with simple logical reasoning; understanding the problem behind the problem.
Maybe logical reasoning is also easier to remember or preserved longer. Seeing, how difficult GGPfB vol 4 is for me, I wonder whether long lasting Go strength has more to do with understanding than with remembering. Although these two might be hard to differentiate.
I'm looking forward to books like the Yi Ch'ang'ho series, which I solved quite heavily before my "break". Really thrilled to see how well they go now compared to before, maybe I'll find some first clues to answer my question? =)
On another note, I wanted to comment on a handicap game by Go Seigen, especially focussing on amashi and hiroi. Well, figures, I'm way to weak to do that but I nevertheless enjoyed Go Seigen's play immensely. So, for public pleasure, here it is:
I forgot, was a game won by 1 point considered a masterpiece-contender or a game lost by 1 point?

Aniki, Black has no eye, which is why he needs to connect. The point is not about making an eye or preventing an eye.
While I now understand the general point you wanted to emphasize, the full solution does involve an eye. If Black mistakenly starts with 1 below, White plays 2 and 4. Both of these plays reduce Black's liberties. After 4 White is two liberties ahead in the capturing race. If White plays 'a' instead of 4, Black is captured but White is only one liberty ahead so Black 'b' is left as a ko threat.
Black 2 below prevents both 2 and 4 in the diagram above. It simultaneously protects two of Black's connection points because of the threat to make an eye if White throws in at 3 below. White has nothing better than 2 and Black is safe after 3.
Just my ¥2 worth.

Re: SoDesuNe paves his road to Shodan
The more unusual the move, the better I remember it... I can't solve some very simple Tsumegos, which requiere a plain move that makes Miai for two eyes, but this one I almost solved instantly.

This one is a nice example for reading and more importantly visualising stones accurately.

Cute little Tesuji. Black to devastate White's territory in the upper left.

Re: SoDesuNe paves his road to Shodan
Nine games to go and I replayed the first 50 of Go Seigen games (starting with his first encounter with Kitani Minoru in 1929 - the mirror-Go-game).
I actually started from the end the first time but after a while (~20+ games) and plenty of losses for Go Seigen, I remembered his accident. So now I start from the beginning and the last game will be from 1961. In total 695 games, but maybe I will change things up a bit and replay Shuei again (got a new technical thingy, so Kindle books are more fun now) or Doteki.
By the way, I'm really glad they abandoned the Oteai system. Go Seigen is 3d the whole time but he is winning and winning and winning (mostly against stronger opponents).
In roughly seven days I will finish GGfP vol 4. I must say after the tough start I am now kinda used to the diffculty and don't have as much problems as before. Maybe my reading is catching up again : ) I also started Tesuji from the Elementary series. I really love the problems, it's been a long time since I did them and they feel just about right =) These should take me around nine days.
Then I'm thinking either attacking Tesuji from Dictionary of Basic Tesuji or Get Strong at Tesuji. Most likely Get Strong at Tesuji to brush up my basics furthermore.

Re: SoDesuNe paves his road to Shodan
Played on KGS the other day. Even used automatch and was glad that I found a game without waiting for a couple of minutes.
Just when things got interesting :o
I went on Tygem then and lost a won game on time because on Tygem you have to confirm a pass.
Ah, well : D

Re: SoDesuNe paves his road to Shodan
Reached 2-dan on Tygem yesterday. Finished the GGPfB series a couple of days ago. Now I focus on Tesuji by James Davies. Still replaying at least three Go Seigen games a day. In other news, I started the "100 push ups in six weeks"-challenge: http://www.hundredpushups.com/index.html.
I hope, I can post a 5-stone-teaching game today (me at the recieving end), because I'm normally way too lazy to review my games. Especially on Tygem where I was quite underranked as a 1-dan. But I didn't know any better, when I created the account : (
