Curious

[caomorto]

Hi there!

I've played a 7 stone game with a friend who is just starting to learn Go. To my first stone, he made a curious reply. I felt it was wrong, and I can't find it in any joseki, but I can't actually see if it is "that" wrong, so I wanted to discuss it with you.

I can force him to bad shape by playing F15, but I don't think he got such a bad deal. What are your thoughts?

It actually is a Joseki. See here for some variations: http://dailyjoseki.com/browse/bwpwxibwnwwmbxj

You are referring to black d18? His moves before that were a joseki. In fact you (white) were the first person to make a mistake by descending to f18 without playing f15 atari first. Black should have played d18 at f15 for a beautiful strong shape. His d18 is also worse than the other move in the corner at e18 as, by not taking a liberty from your two stones, he doesn't threaten to cut at g17.

I didn't knew dailyjoseki. It is a great resource. Thanks.

I was actually talking about F16, which no one had ever played against me before. It caught me off guard. I thought I could leave G16 as is, but F15 would be top notch.

Thanks.

You can also look at variations on Josekipedia and Eidogo. (I prefer Daily Joseki for some things, but it is based on a database that includes rare moves, experiments, 16th century josekis, etc. F16, of course, is just a normal corner sequence.)

Today someone also told me about Josekipedia. Two things I didn't knew and that will help me greatly: Josekipedia and DailyJoseki.

Thanks.

Of course you could also just buy a printed Joseki dictionary like 'The 21st Century Dictionary of Basic Joseki'. In comparison to josekipedia.com this book (actually these books since there are two) is compiled by a professional Go player.
Josekipedia has some funny moves (or whole sequences not found in my Joseki book) and without commentary I don't think you can learn much, let alone differentiate between an actual Joseki or a bad variation - unless you are strong enough ^^

That's also the reason why I tend to prefer dailyjoseki.com. At least this database is compiled from pro games so these moves were actually played at the top level.
