3-5 point Josekis

    Keywords: Joseki, Index page

This gives an overview of 3-5 point Josekis that have a page (or several pages) on Sensei's Library.

For each joseki a standard sequence is given (this is one of the more common ones, but need not be the absolutely most common one), and an overview of pages dealing with that joseki and its variations.

Is W5 above correct? 38 Basic Joseki gives this:

3-3 invasion followup

38 Basic Joseki gives this followup line, but Kogos Joseki Dictionary calls W1 an error in move order.

Herman: Ishida agrees with Kogo's, and says that white should make the W1-B2 exchange before the white+circle-black+circle exchange.

Kogo says...

Kogo gives this refutation with the the comment that with cutting points at both circle, white is in trouble here. Of course, sometimes Kogo's analysis verges upon the hyperbolic...

Herman: Ishida gives the exact same refutation diagram Kogo's gives (much of Kogo's is taken from Ishida). However...

Professional play

Herman: Of the 52 games I have on record with this position, white next plays a 25 times and b 22 times, so a is in fact the most popular pro play in this position.

[Diagram]

Professional play (2)

Herman: Of the 25 games where white plays W1, black next plays a 17 times, b 6 times, and c 2 times. Apparently, there is more to this position than meets the eye.

[Diagram]

Professional play (3)

Herman: And finally, of the 6 games where black responds to W1 with B2, each of the continuations a, b and c is equally popular, with 2 occurences in pro play (of course, 6 games is too small a sample to draw really meaningful conclusions about that)
