The move by my opponent surprised me. It seems that J16 would kill almost all aji in that area and give him a large center territory. Now there are some possibility’s on how to invade/reduce. But first I want to play in the lower right. My opponent tenukied so I should try to punish him for it locally.
Some analysis.

After the most likely response is 2 and with a being my sente the total points for this white group looks to be roughly 10 whereas the reverse sente is worth 25 points with a net difference of 15 points. Probably more, because my new stone helps my 3 weak stones in the middle. The problem is if my opponent tenukis again I will be in a bad position on the top side.

I count 70 points in the middle. I can probably reduce some of it with my marked stones but in reality they are very weak and will probably have to run more than reduce.
B: lower right corner: 40 points Lower left corner: 10 points upper right corner: 15 points left side: 5 points komi: 35 points: = 105
The points favor me (I needed to recount this twice since I couldn't believe I was in the lead with that kind of board position) the question is whether I can keep it in the endgame and I don't think so. The essence of this is that I need to extend from my 33 or this game is probably over. I can't risk that white tenukis from my move in the lower right (But I still want it so bad!)

I think this move is pretty hard to answer. You have a really nice extension from the top but I would be pushing him towards my weak groups. If I allow white to connect his R11 stone with the thick group on the bottom side I will be in a world of hurt. He would be able to revive the marked stone and my stones will be weak, floating and probably dead.

Yeah I'm stupid. I read the attachment at Q13 and thought I found a great play. Now though, my stone is dead and I lose a lot of aji in that area. I originally wanted to play a few forcing moves and then cap the K17 stone, but after my disastrous aji-keshi play he can ignore easily so I'm forced to cap now

I'll guess I'll just play standard here. I'm planning on building a bit of strength and influence here and then invading the white moyo. This is what I'm expecting and what you could consider the 'normal' way. Of course my opponent could get tricky with crosscuts and all that
The essence of this is that I need to extend from my 33 or this game is probably over. I can't risk that white tenukis from my move in the lower right (But I still want it so bad!)
stones will be weak, floating and probably dead.
