Welcome!

My real name is Sebastian Heuchler, I'm a 22 year old German student living near Würzburg, a small city in Germany. We have a local Go club where I play sometimes.

My [ext] blog covers some of my Go-related activities, please feel free to have a look. It's mostly in German, but Go-related articles are often released in English.

Mainly using the account mafutrct, I play online primarily on KGS (I'm a KGS+ subscriber). My current KGS rank is in the range of 1-2 dan, my IGS rank is about 4 kyu (I did not play on IGS for a while) and my oro rank is 4 kyu. I'm about 1 kyu in Germany ([ext] EGF Player Card).

I learned Go in November 2006 while watching Hikago ^_^ and enjoy it quite a lot. I'm currently busy, so I can't study as much as I wanted to. Besides playing games I read a lot of books and do some problems.

Teaching

I give lessons (free, of course) and teaching games for 4k to 10k players. All in all usually about 5-15 hours a week under different accounts.I do not take any regular students, but feel free to join my occasional game offers.

The Temple

I'm a member of the Temple ([ext] http://www.templeofgo.com/), an international studygroup of players with a wide variation in strength. All members are dedicated to the progress of the carrels, each with four "monks". The "yellow carrel" consists of Frank, Luc, Thomas and myself.

The GoTeachingLadder

I'm also an active member of the GTL. Please send us your games so we can review them! :)

Recorder

Greatly enjoying to watch videos of various people's lessons i decided to capture some public lessons myself. The XVID/LAME encoded records with nearly lossless quality can easily be downloaded via torrent. If you want me to record your lesson, just drop a message to the KSG account "Recorder".

Downloads

I provided some files that might be useful. I'm constantly updating as need arises. Please have a look at [ext] my blog for a huge collection of ebooks.

Events

2009.07.04 7. Studentisches Go-Turnier in Potsdam

I [ext] blogged about this tournament live.


2008.11.28 Berliner Kranich

Have a look at [ext] this blog entry


2008.06.01 The Enclave Tournament

A double elimination tournament sponsored by Slate and Shell and Alexandre Dinerchtein 3p. I ended up placed 5th out of 37 players.

Sadly there were frequent delays and problems. Of the 8 games i played, i won 5 by default because my opponent did not respond or show up. I'm not sure i enjoyed this tourney after all.

2008.05.24 Darmstädter Go-Tage 2008

One of the most famous Go events in Germany. The Bessunger Schloesschen is a really nice place to play. Also, the weather was great (maybe slightly too hot). I missed the first 2 days, but entered the weekend's main tournament as 1 kyu and won 2 out of my 4 games. I misread most simple semeai and ladders and i'm quite displeased about that. Maybe i was just lacking sleep, but it felt like i lack toughness and grip.

2008.04.26 12. (or 13.?) Münchner "Bierseidel" Go Turnier

Very nice tourny, i enjoyed it a lot. I played 5 games, won 4 and got promoted to (German) 1 kyu. [ext] http://www.schorsch.com/go/bierseidel/index-de.html [ext] http://www.dgob.de/tourn/tourn.cgi?f=08demuen.txt&mode=cml

  • Game 1: w vs 2k

A funny game, after some early reading mistakes i found a great way to sacrifice an important group to revive an even more important group and won a seemingly lost game.

[Diagram]

White just split and a big fight seems inevitable.

White now plays some really bad moves and black is easily ahead. Later, black forces white to take a huge territory, but builds an even bigger framework + thickness himself. White stupidly overplays in this moment.

[Diagram]

Black splits - more fighty stuff coming.

White will later sacrifice the central group to gain thickness to play at Wa. After a few tesuji (and mistakes by both players), the white blob on the left side is alive in sente.

[Diagram]

After this sequence, white wins.


  • Game 2: w vs 1k

I played terrible, was forced to live in an ugly way and had to overplay, but failed (of course). I'll have to study some corner patterns more.

  • Game 3: b vs 2k

A slow and fighty game, after a joseki mistake by my opponent i was able to kill a group. But later, i messed up in a big fight and lost my center group. After a black double kakari white deviated from joseki, missed a ladder and black was able to recover the earlier loss. White resigned soon after, but i felt bad because i did not deserve to win this game.

  • Game 4: b vs 1d
[Diagram]

Black to play. I had no idea what to do.

I encountered an new situation in fuseki and was clueless how to continue. After some small fights i initiated for no reason, i felt slightly behind. I then built thickness and after a white tenuki i launched a large scale attack. Although i did not kill, i was able to build a strong outside and reduced the white potential globally. Later i found a few Sakata-Eio-(2 kyu version)-like moves and lived in a beautiful way inside the opponent's territory using dead stones and empty triangles. I completely dominated endgame and won by resignation. After my depressing 3rd game, i felt a little better and decided to finally eat breakfast.


Game 5: b vs 2k I was in a good mood, it was pleasantly warm outside and since my opponent seemed to like to play fast, we played about 50 moves of a rather normal opening (including mini chinese) in a few minutes. I got magnificent thickness and a almost-terriroy medium scaled moyo, he got some secure territory and a huge framework. I invaded, he attacked and after some funny fight, i sacrificed my thick group (lol!) to secure 2 other groups and begin endgame. The game was rather close, i felt ahead by about 5 points. A few moves later, he threatened to split 2 weak groups. After spending days on goproblems.com, i read the fight and the 2 tsumego to the end and played a big endgame elsewhere. He then attacked and split, but i did not mess up and about a dozen moves later he noticed my unconditional life (in sente) ^__^

After i killed his desperate invasion and grabbed many points in endgame, i won by a huge margin and was quite happy to conclude the tournament with 4:1 stats, winning a book price.


[Diagram]

A bad way to play for black.

Afterwards i played a short teaching game with Viktor Lin 3d from Austria. I again noticed that besides better tsumego the skill that probably most differs between dans and kyus is efficiency of moves. I was really surprised how evil a simple shusaku's kosumi can be on the right board. I resigned after about 50 moves. We reviewed the game together with Yan Haitao 5d, the tournament winner, and i relearned a new technique.

2008.01.09 Master Course 2008

with Takemiya Masaki 9p, Kenmochi Jo 7p and Kobayashi Chizu 5p in Vienna. We played and reviewed lots of interesting games. We got to solve many tsumego und despite Takemiya's "kore ha isi tsumego" i was unable to solve most of them >.< [ext] http://www.goverband.at/registration/takemiya_info.php

2007.12.26 Ninbo Blitz Tournament

1 minute + 3 moves per 20 seconds, handicap reduced by 2 stones. I entered as 1 kyu and played 4 of 5 possible games, losing 1 game due to a stupid mistake, winning the other 3. Anyways, i was placed 3rd out of about 15 players.

2007.09.10 September 2007 3-weeks KGS+ Tournament

I entered the [ext] European/American daytime kyu division. I stopped playing when placed 4th because of lack of time. After the tournament finished, i was placed 8th out of 59 players.

2007.08.01 The War Of The Worlds Tourney

I took part in the first WWT. My group consisted of Asap 9k, farlaanjar 4k, NateC 3k, Sensi10 14k, Timetodie 1k and myself (4k). The account i used in the tournament was "Mafutrct1", not Mafutrct. See Hikarujr for more info on the tournament and rules. I played 1 game. It was an even game against an 1 dan, black (that's me, i entered as 4k) got -14.5 komi. I did some stupid mistakes, but in the end i won by 17.5 points.

My team won the tournament! see [ext] http://www.youtube.com/watch?v=lwWDcaoFK18


Books

I recently decided to keep track of the books i read. I'll list then here and leave a short comment for each. I won't add books i read in the past, tho, to keep this list up to date. Think of this as a short book-review :) I'll add in chronological order.

2009.03 Get strong at the Opening

2009.02 501 Opening Problems

Mostly very easy, just the last few pages proved to be really difficult. I guess SDK players can enjoy this book the most.

2008.06 Lessons in the fundamentals of Go

Very good, changed my way of thinking a lot. Recommended for any SDK or low dan.

2007.10 Elementary Go Series, Volume 3 - Tesuji

A few month ago i read this book for the first time. Noticing i lack reading and tesuji power, i decided to read it again. While the first few chapters were extremely easy for me, i encountered major difficulties in the last chapters. Still, i got reminded of a few moves i had forgotten. A very useful book, i'll read it again for sure sometime.

2007.09 Nagahara Yoshiaki - Strategic Concepts of Go

I kind of randomly decided to read this book next.

Most books keep telling you to watch out for only 2 things: shape and reading. But this book's idea is somewhat different, like, well, like "strategic concepts" :) I still have to get used to this.

(While reading the first 2 chapters:) Also, i immediately noticed the increased niveau. This book is probably above my level. I get everything which is explained, but i was totally unable to find the next move in the shown example sequences.

After reading the first chapters, i became used to the presented ideas. I had about no trouble understanding the following chapters and even got a lot of moves right. Beginning with the problems section now, i still get no perfect answers on my first try, but i'm very close. I think this book already made me a bit stronger =)

2007.08 Elementary Go Series, Volume 5 - Attack and Defence

I found myself losing in chuban too often, so this is the first book i read in a while. Makes me realize i lack a lof of basic fighting moves.

There are 20 final problems included which require understanding of the whole book. While a few are solvable in a few seconds, other require some meditation. I got about 80% right on my first try and am quite unhappy about this. I'll learn more about this topic itf since i came to like reading all kinds of fights. ^_^

The book is easy to understand and covered all variations i can reasonably think of in each topic. I recommend reading this for every SDK.


Read more!

Here are some simple reading problems. I misread most of them on my first try =)

Easy ladder problem

[Diagram]

Can W capture the marked stones?
