My Go history

I was first exposed to go through the manga. Played regularly with Peter Passow 4D in Berlin, and James at TU Berlin. Moved to Essen. Participated in German 4th Bundesliga with Bambus Bochum (Sprösslinge). Went to EGC in Bonn.

Now back in Berlin, playing with Kalli Balduin at the Martha Go-club.

My book reviews:

Joseki:

• 38 Basic Joseki. My first joseki book, before moving on to the Ishida dictionary. It exposed me to the very concept of joseki. It has been said about this book, that many of the joseki presented there are outdated. But I would much rather see it as invitation to try these joseki out in games!

Tesuji

• Tesuji - the book. Simply an amazing book that will make you stronger. I went through it at least twice.

General Theory

• The Second Book of Go. This is a great book for beginners, it helped me a lot. But what makes it really great are chapters 7 and 8, explaining capturing races.

Middle game:

• GO Invasion et reduction book review

Endgame:

• 200 Endgame Problems. One of my favorite problem books, because it is so applicable to you game. It is not the hardest book, if you already know a bit about endgame counting and tesuji.
• The Endgame. The first chapter, going through a pro game endgame, is quite challenging. The next chapter about counting is quite good. The third chapter about endgame tesuji is also quite good, because the tesuji are ordered by theme. This is an advantage over 200 Endgame Problems. The next chapter 'macro endgame' is about finding the most profitable big endgame move and is quite difficult.
• AbsoluteCounting. This is a really good book. First of all, big names O Meien and John Fairbairn as a translator are behind it. First, it teaches how to count territory, when there are endgame plays left. After that it teaches how to count the values of moves, which is really straigtforward once you know how to count territory. We learn about the value of reverse sente, sente and gote moves and deiri counting and absolute counting. In absolute counting, gote de-iri values are halved in order to compare with reverse sente moves. Sente moves have not really a value, but are regarded as privilege. Nonetheless, a value can easy be attributed. Next, we learn about in which order to play moves. For that, we use the absolute value of the move, not the de-iri value. Then, we learn how to approach tedomari problems, where only a few moves are left, before the value of sente significantly drops (the word tedomari does not appear in the text though, see also Tedomari is Worth Double). For these kind of problems, we use de-iri counting, we attribute a value to sente - 1/2 of the largest gote move (in the de-iri logic) after the candidate moves are played, usually much smaller than the candidate moves - and compare. Later, the value of sente in the miai counting (absolute counting) logic is stated as roughly S/2, S being the miai value of the largest sente move. The 'uncertainty' of this value is stated as S/4. This concept actually helped me a lot, I did not grasp the concept of 'value of sente' very well before reading the text. Further, there are examples of real endgames from pro games. These are quite difficult for me still.
