Summary - Joseki - San san under Hoshi in a general case.
White plays to stay alive in the corner
Black now has a few "joseki"[1] choices for .
- Playing a results in influence in gote, see Hane at the head in joseki1.
- The double hane at b? is considered somewhat advanced and severe. It is usually played if Black wants to keep the corner and some influence in exchange for a ponnuki on a side[2].
- The inside cut at c? lets the invader choose between the corner in sente or side in sente or corner and an opening to the side in gote (might be even double gote as a result of ladder breakers). Some people consider the inside cut to be a 10 kyu hamete because White may get some advantage when she is very careful not to make mistakes.
- Tenuki is not a good idea.
[1] The invasion at 3-3 itself isn't considered joseki and shouldn't be played too early as the thickness gained by the opponent is superior to the territory gained by the invader.
[2] The ponnuki is normaly at the upper-side here.
