Responses to stone on 5-5  
  • From professional play:
    • a: pseudo-joseki 1
    • b: pseudo-joseki 2, 3
    • c: pseudo-joseki 4, 5
  • From Josekipedia:
    • d: pseudo-joseki 6, White can choose a peaceful or a fighting variant.

Andre Engels: Not much joseki is known for the 5-5 point, not only because it is played rarely, but also because common wisdom seems to be that a 5-5 point is better left alone than approached in most cases. Here are some variations that have been played by professionals more than once, and thus might be considered proto-joseki.

pseudo-joseki 3 (white 11 at a followed by black b or at c)

pseudo-joseki 4 (white 11 at a)  

Actually just once this sequence, but I wanted it in because earlier moves in the sequence have been played more than once.

Shouldn't white 11 be at "b"? ~srn347

Chris Barnes, 2kyu? Back in the '90s, there was a rec.games.go newsgroup discussion that recommended a 3-3 invasion under the 5-5 stone. Has this move been seen in professional play?

  • PJTraill: I do not know about professional play, butJosekipedia as of 2018-03-06 gives this, with a peaceful variant at a and a fighting variant at b as below. The comment on 3-3 is "Usually this invasion point is the best, because it makes Miai of the extensions W3 and x (6-3 points)." attributed to Alexandre Dinerchtein(3p - Korean-Style Insei League 13.11.2010).
