Back when Terr posted his trigger post as shown below, saying that if B1 then he would play W2, I was seriously considering whether or not I should approve.
The direction of play for the west side white group is not to the west. Not only is there very little happening there, there is very little territory. Black can undercut from both sides. The only way that this group can make a significant contribution to the game is go eastward, like this:

This way, it separates two eyeless black groups.
Black, conversely, would like to connect his two eyeless groups, thereby resolving most of their life-and-death issues and creating a big wall. Once the life of the lower black group is secure, the invasion at 1 or similar is easy.

White has the same direction of play goals. So does black. But now, because of all of the aji keshi plays, white can get the play at W2, splitting black, but keeping himself connected.
In summary, black's aji keshi play has strengthened white so that plays like F7 that were not possible before are possible now. Sure, we have to play an extra stone or two on the west side to kill the black sacrifice, but in the long run we gain more. IMHO, black is being penny wise and pound foolish.
Easy to understand. If white extends along the right side, I continue with J16: since I have an enclosure in the top right it will not make sense for white to pincer as in diagram 2, and this order of play gives me more elbow space against white's top group. I see no good alternative response for —J16 seems unfeasibly slow and the shoulder hit on top of doesn't look very good either. Thus,

Okay, so the last time we moved in this vicinity, I tried to do something fancy, with J16 intending to sacrifice D18. The only other alternative I had read before is living small, with the diagram below. Joaz changed my move to the first move of that diagram.

This diagram's actually kind of intriguing, but I think it'd be better to settle our groups more solidly in almost-sente and be able to play somewhere else. Here goes.
As an aside, I'm not sure about this board as a whole, but that prisoner count is starting to look helpful.

I approve.
Younger brother is making good moves, but again for maybe not the best of reasons.

There are at least three possible lines here: 1) The inferior sacrifice. 2) The better sacrifice 3) living small but solid

He assumes that when he intended to sacrifice our upper left group as in the first diagram, and I changed his move, I therefore did not like the sacrifice, and was aiming for the third diagram. This is not true. There are at least two ways to sacrifice here, and I changed it allow the better sacrifice. At the same time, I left open the live-small option. The move at G16 - which I am going to approve - allows either the second or the third diagram.
He further assumes that I'm guiding this. That is not really true either. If I were in charge here, we would not be sacrificing, nor would we be living small. We would live by fighting in the center.
Terr has assumed that I am doing this, and so he is following my lead, trusting that I have a good plan. However, I am in the dark almost as much as he is. It is Shapenaji who has decreed what we will be doing, and I'm just following his lead, trusting that he has a good plan.
This leads to two possible outcomes: 1) Shapenaji intends to sacrifice, and prefers the better sacrifice, while Terr aims to live small because he thinks that I prefer it. This will cost us a bunch of prisoners, but will probably provide great amusement for the audience. 2) Shapenaji intends to live small, and Terr will play to live small, and we play the next several moves with no loss of prisoners. I say 'no loss' because I will be chosing the live-small option when possible.
An additional comment:
A few moves ago, I was undecided between living small and sacrificing. I now prefer living small. This is because of the recent white aji-keshi plays. As I noted in my last post, the aji-keshi has strengthened us enough so that we can forcibly push through at F7, like this:
Being able to push through eastward like this keeps pressure on the black center-left group from the south. That only means something if we are alive in the north. So keeping the north group alive is worth more now, and I don't like the idea of sacrificing it.
Heh, well, it's continuing like I thought, poor Joaz, he must think me truly insane to like this small life... but there it is, maybe I am insane, but I really like the aji here for white (see earlier comment)
Regarding the sacrifices, I don't like either of them, the wall isn't really that strong, black ends up with a towering wall over us with no weaknesses. But if you're going to sacrifice:

"a" creates rather a large ko, if we have the threats (which we don't) "b" builds thickness and threatens the ko
I don't particularly like this, white has thickness but nothing to attack, he would have to *gasp* use his thickness to make territory... meh, not my style.
The small life looks odd at first, but I think there's a lot we can do with it
if i was to play such games(Big Brother) with professionals i would play moves i dont understand if they tried to cut as such. i am not saying that cutting is a good move! it probably is bad but i am not sure. but when they start the push..and if you dont cut... the stone loses it's merit. in korean professinal revews you will see that word "merit" many many times. i hope people grasp that concept and use that in their reading.

looks inanely heavy but seems to put real pressure on white. I can not identify white's correct response.
hurts my top right corner.
won't do.
