Now would have been a good time for black s6. It's certainly sente now as there's no big opening points left that white could satisfactorily get two of in exchange for allowing s6 and r7.

Re: #240 awef vs jeromie
No problem, awef. This is the first week of classes (I'm a teacher), so it's probably good that I took the weekend off of this game.
I looked at the bottom around L3 and top around J17, but as far as I can tell black needs to respond locally to this reply or he will get a bad result. That means I can play this in sente to stabilize my right side group before attacking the weaknesses on the top and bottom.
I primarily considered moves in the shaded area, especially J16 and L16, though I did look at a (makes L16 much more playable because more ladders work for me, helps keep black from reducing by extending from the left side, and threatens a nice follow up at d), b (this bottom weakness is still big), and c (one more move here would make my territory on the right side much bigger). Ultimately I decided that now is the time to attack the weakness on the top... if black gets to solidify that area the game looks very bad for white.
I chose the shoulder hit because I want outside influence, and while I can separate his stones with K16 black will get a nice outside wall in the process. Almost decided to switch to the star point at the last minute, but decided it was better to go with my initial instinct.
I figure keeping this stone connected to my group is important. I figure white will push once more, which I'll answer. After that, I suspect white will play around L3.
I get the wall I wanted; I'm content with this. I looked at playing D12 first, but I can't ignore black to follow up if he hanes at H16. Getting this solid wall first is important for white. I'm expecting a play on the left side around D12 or a play on the bottom, which is still big for both of us..

I may have missed this earlier, but what do you plan to do with the wall?

There are a few ways I plan to use it: 1) This makes it harder for black to turn the upper right quadrant of the board into a very big territory. (Though I'm not entirely out of the woods on that yet.) 2) I can possibly use it as the foundation for some center territory of my own. 3) I can be more aggressive in certain areas of the board (e.g. the bottom right) where more ladders will work in my favor.
Black's move is a relatively small reduction, but it is sente so I guess it makes sense to play this now. I imagine this is the sequence he has in mind:
Black has a lot more territory than white, but I think this move is sente (white has a follow up at C10) and big. I'm estimating what white is about 25 points ahead in territory (though I didn't try for an exact count), but at this level I don't think I'm out of the game yet. Still, my follow up to this needs to be something that does more than secure boundary lines.
I considered playing in the lower left corner to keep myself from getting sealed in there, but I think this is bigger.
I was tempted to keep playing locally with the marked move (threatening a), but playing here is likely to end in gote and only makes a really big profit if black blunders. Playing on the right side is another sente move (I think) and starts to look like I can make 5th line territory in that area (if I fix my weakness at b).
The other area I looked at is a move around a or b to move my lower left group into the center and keep black's two big groups separated, potentially allowing a later invasion in one of the marked areas. I think preventing black from turning at my actual 46 is more important, though.
