Hi,
what is the best way to handle the following invasion ?
Let's say I want to keep as much territory in the corner as I can.
Let's not. As others have indicated.

Not easy to find. As Calvin points out, pros do not play this way.

The problem is that your goals are inconsistent with your previous play. If you want to keep as much as possible in the corner, you should only extend to L17. . . .
However, if there are still only a few stones on the rest of the board, you should not be looking to settle for as much as possible in the corner when White invades. There must be larger areas on the board
Worth repeating.
However, even if there are larger plays on the board,
is probably a mistake. Punishing it has a psychological value. Even better, if White makes small life with gote, he might not even realize he has been punished.

"a", "b", and "c" are standard attacks against
. "c" the least common. The general idea is to threaten
and make strength as White defends it.
is usually a mistake, unless White has a stone at "d" or something. The
stone is important for two reasons. It strengthens the Black corner, and it makes it impossible for White to make much territory with
, if White can live at all.

is a strong attack, making it impossible for
to escape and difficult for White to sacrifice it. White would like to play the peep at
, but
makes
a nice play. White will have to find something else.
Play around with this position. Maybe White can make small life, maybe a ko, maybe not.
