I give up my stone in the right upper corner for now, I might use it as aji later. Is this the correct decision?
-- yes

is the net the proper move, or could I tenuki?
-- can catch on a larger scale; after the net, the one space jump to the left feels close to the strong group

is this move too slow? Or rather, not doing enough. Either C15 to enclose the corner completely or D10, C10?
-- a bit unbalanced, I would play bigger on the left side

is overplay and rightly punished. Shame on me. No question, just a mention. The moves following that are an attempt to make something of the mistake, but I see quickly it doesn't work. And so I make a solid wall with...

Is this too heavy? Play a lighter shape?
-- no it's ok

what is the best move here? How to catch this cutting stone?
-- extend your weak stone upward

Proper timing? Or extend once more to K8?
-- extend once more: you can still cut off those 2 stones later
Thank you!
