;B[pf]C[This is a standard joseki. White often plays tenuki now, but playing the keima move is also common]

;W[pb]C[White responds to live in the corner. Black has gained some more influence and can now start developing the upper side as well.

However white probably will not reply to blacks jump and will play tenuki again. ]

(;B[pf]C[In the first episode we made we talked about the position you see on the board here. In that episode we explored a trick which can occur when white invades the corner at the 3-4 point after black has occupied the corner with takamoku, the 4-5 point. Do you remember that trick? Check out that episode if you have not seen it yet. In this episode we will explore the 4-5 point a bit further and talk about another trick that you should be aware of when invading the 4-5 point at the 3-4 point.])
