C[Just considering the 3 top right corner stones, this play used to be a respectable joseki.

However, in this board position no pro would make this move.  So what are some good ideas for White?];

C[Just one possibility.];

C[A very satisfactory result for White.

White's move here may look small, but White's group makes eye-shape.

Moreover, Black's marked stone is weakened.  Before this sequence, this marked stone had been pressuring White's approach move.  Now the tables are turned.]

    C[Black can take an attacking posture here, while creating a lower right framework.

This result is terrible for White.]

        C[... now Black can switch to the top left to ruin White's potential.];
        W[ce];B[df];W[fd];B[ff]
        C[White mimics Black's strategy in the top right, but Black's top left stones have the marked stones for support.

Black continues to fight where Black has the advantage.

Now Black can aim at the top left corner, e.g., with A.  And invading the lower left with B is another headache for White.]
