Hi Wellington,

You played well up to here. Did you read the cut P11.

Even if you want the right side, you still push first at Q17.
After W replies at Q18, you can still decide which side you want.
But not pushing first is too good for W.
After the Q17-Q18 exchange, if you want the top, then hane p18 + connect P17.
Else if you still want the right side, then turn at the

game move;
W can tiger's mouth S18, you atari S17, W connects, you have sente.
A standard corner shape; good to learn it.

Nothing to build there for B, unless you want to attack W's dragon,
but it's not your target at the moment. Better to tenuki and take a big point instead.

Not good for W.

Yes, you wanted to attack W.
W ignored

-- did you read N17: if W pushes at O16,
you connect N16, happy to give up the (now) useless Q16 stones.
Even if you don't see N17, M16 is also a big local follow-up.
W's dragon is a problem for W forever. It is
negative points for W.
You can tenuki and take the big points first, and let W worry about it for a long time.

Strange feeling. L9 direction ( profit on the
outside ) is natural.
