C[SoDesuNe:
The 4*4-corner-enclosure has three (main-)weaknesses: A, B and
your move 2. That's why it is considered a bad play to take away
simple one weakness, because you are still open for attacks.
To take the open corner or approach with C or D would be far
better.]

C[SoDesuNe:
Nothing wrong with this move, I just want to express that approaching
his bottom right stone would be good aswell.]
BL[1491.487];W[qf]WL[1491.12];B[of]
C[SoDesuNe:
Mhh, somewhat tricky. Usual is either A (most common), B or maybe
C. A and C will lead to different Joseki.]

C[SoDesuNe:
This is a small move and bad shape. Protecting the corner has
no value here, as White can still come in from the other side.
Compare this to the reason why enclosing the 4*4 is usually not
good.
A makes good shape for your, and attacks the two White stones.]

If you simple want to connect, the Bamboo-Connection at A is
better.]

C[SoDesuNe:
Usual the response would be at A, but here the corner is pretty
uninteresting, there are wether points in it nor a base for your
group to get two eyes.]

Be aware of your cut at R15! If you simple connect White can't
connect to his lonesome stone.]
