Basic ideas for large 3-4 enclosures

Post by paK0 »

See title, I'm looking for some introductory information on how to deal with 3-4 enclosures, specifically large knight and two point jump.

I checked senseis, but the information there is pretty bare overall.

Josekipedia on the other hand is a bit overwhelming, lots of variations with little explanation.

Something ideal would be a lecture or two that go over the most common post alpha-go variations or a book that gives a little introduction to the situation.

Thanks in advance

Basic Idea: Usually you should stay away from the large knight move enclosure until quite late in the game (only think about invading or reducing after some moves happened on the outside). But this is by no means an introductory issue. Pros struggle with this question as well.

Some example games:

a is the best option, b if you insist playing in the local area

You ask about a book or lecture. If you want to learn about tactical situations today I recommend this different approach. Aquire a pro database like Go4Go, search the situation with Kombilo and review with AI. (Books are not up to date and wrong quite often.)

I like tsume go books by the way, even the old ones :)

My approach is different to Gomoto's: attach early and often to large low shimaris. It might not be the best but it's fun!

Thanks for your suggestions, however I don't think either way is the right approach for me.

@Gomoto: I usually go over my own games with LZ and get my joseki from what I get there (so at least its relevant to the games I play), but these enclosures don't show up often enough to get a cohesive picture, but they are there often enough that its a pain not knowing how to deal with them. It seems like LZ is highly sensitive to the local and whole board situation, something that I can't replicate, so I'm looking for a handful of ways that are "just ok" but generally applicable.

@Uberdude: I really don't like this "go in and improvise" approach, more often than not it ends badly for me.

IMHO, in go you can't really avoid some degree of jumping into the river to learn how to swim. Fortunately, when you drown, as I have done many, many times, all that dies are stones. :rambo: :blackeye:

Still try to swim, though. Sometimes I feel like I'm just flailing.

Here's an sgf with some of the most common new josekis from AI around the big shimaris:

@Bill: True, but that doesn't mean I can't get some information beforehand

@Uberdude: Thanks, that is amazing.

strong AIs, like Go Seigen, seems to see small shimari as a bit slow and liable to overconcentration
The first time I read this, I started wondering since when we started classifying Go Seigen as a strong AI :lol:

Fuseki example were an early attachment seems reasonable:
