at:

• a hane: black can block (see variation), extend (see variation) or cut (see variation)
• b, the wedge (see variation) requires a favourable ladder.
• c invade (see variation)

Recently reevaluated:

• e the stretch &peep has previously been criticised, but is nowadays preferred by AI in some contexts. See Noseki - 4-4, low approach, attach on top, peep.

Not joseki:

• d, see BQM 97.
• a move like f does not put enough pressure on the attaching stone and allows Black to play the bulge at e.
