Worrying about the three

the three

My group is pretty much invincible now, so I think this result is fine for me. Also, his marked stones are kind of useless now:

I'm happy with this result.
But hey, I haven't really studied Go for awhile now, and it's not like I'd know if it's good or bad for me. Can't say I really care that much.

I've heard that a number of pros - even though they're pros - say that they are not good at attacking. The trend seems to be that territory is where it's at. When you attack, you need to get profit from attacking. Ultimately, you need to get some points - maybe by killing a group; maybe by creating a formation during the attack. Maybe somehow else. But undeniably, you need to make sufficient profit.
Looking at the white stones on the board, white's only points are on the left. He has some influence in the center, but I have strong positions in the other parts of the board.
Given this, I see only one way for white to make significant profit by attacking my group: by killing it.
For example, let's say that he gets a bunch of moves by attacking me, and I live. He'll get a wall, hypothetically, something like this:

What did white get? He got a wall, and a few points on the left.
If I make a solid position on the right side, I'll get more than that.
So, this leaves me here:
* If he can kill me, I should defend, of course.
* If he can't kill me, I think it's worth it to tenuki and play on the right.
So the question is, can he kill me?

Also, a third option comes to mind, which is to keep white split:

Doing so keeps the possibility of having the marked white stones become a weak group later.
But maybe that will give him more profit.
I'll ponder it for a bit.

I think that Kirby got ahead in this game by pushing white at D11 and E12.

For observers:
Not sure, but feels like white's hane below could have just been the more calm extend at "a" which doesn't leave the cut?

This seems way too conservative. It attaches to a weak stone, and makes merely two points.
White has several weak stones that could be attacked:

If W simply replies bluntly --

while W gains useful stones on the outside.
The
stones are not weak; they are
light -- there's a difference.
