Further thoughts:
Actually, I'm convinced it's better to let White connect underneath. He's on the second line, he's not making points, I'm alive and out to the middle, in sente, and have the endgame push in the bottom left as my privelege later:
$$Bcm29 Prisoner Count: B-0 W-0

Even so, it's better than White blocking and having the endgame at "a" later. I want sente really badly here. I'm 95% sure this is what I'm going to do - the remainder of my problem is the top vs the top right, and I'm completely torn. However, that's not something I have to worry about just yet. One final consideration:
$$Bcm29 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Bcm29 Prisoner Count: B-0 W-0Can White do this? I think not, at least, not now White has forced me to reinforce, which is yet again leaning me towards getting my sente back.

Ok, I've decided. I've also decided M17 would have been better than D2 I think. White is threatening to build a lot up there. At least his shape is flat, but he can develop it nicely, so reducing is very large.
If he tenukis now to take either the top or top right, I can swallow this stone in sente:

@entropi:
Actually, it's more the aji than the points comparison. If White blocks, Black gets to continue pressuring due to the following sequence:
$$Bcm21 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Bcm21 Prisoner Count: B-0 W-0Due to this, it's better for White to have a group that can escape to the center easily and lightly. Black then has to take the corner really, else the slide seems a poor exchange, and Black then has to accept gote as well. It's more a case of "picking a move that doesn't let your opponent poke you around for a while" than direct points, because it's the poking around in the midgame that often picks up 15 to 20 points if there's a weak group involved.

$$Wcm21 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Wcm21 Prisoner Count: B-0 W-0Playing like this would be the most severe way for black. Because of 21 exchanged with 22, black is now thick in both upperleft and at the bottom, while white would have two weak groups.

$$Bcm21 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Bcm21 Prisoner Count: B-0 W-0Presumably, black doesn't play "a", above, because white could play "b"... I guess.
If this is the rationale, perhaps someone could elaborate on why the following picture is worse for black than the game. I guess black gets few points on the second line this way, but I'm not really feeling it, yet...

@kirby: My justification is that moyo potential is more useful than 2nd line territory. I'm also concerned that White jumping out there gives a potentially useful tesuji at G3.

if he happens to hanne then i will cut and fight strong.
all i want is sente for 'a' and 'b'
if his group gets attacked then his bottom will be erased automatically.

Well, my Go has taken a bad turn recently, and this game exemplifies why. I was looking at this board last night thinking "Why do I again feel like I'm on the back foot?" and realised it's all my fault. I'm being a pink pansy. That's not to say that might not be appropriate sometimes, but Go is a game of strategic warfare, and magicwand eats pink pansies for breakfast. William Wallace didn't run away because the English had a big army. General Leonidas didn't decide Sparta looked better under Xerxes' control. They stood, they fought, and they took what they believe was rightfully theirs, fully accepting that they might die trying.
If I'm not going to play Go with that attitude here, I should leave the stones in their bowl.
As I analysed this position, I knew I should hane. Everyone hanes around the head of two stones, but I just can't see any way of being happy after White cuts:
$$Bcm31 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Bcm31 Prisoner Count: B-0 W-0Sure, I
might be ok, but I might not, and if I die, I lose. Then it struck me - why do I want two groups here anyway? I'm surrounded by enemy stones. I don't need anything clever or tactically sharp. I need thick, solid, strength. It suddenly dawned on me that I should have done that in the lower left too - Divide and Conquer!:
$$Bcm31 Prisoner Count: B-0 W-0
Click Here To Show Diagram Code [go]$$Bcm31 Prisoner Count: B-0 W-0So, I'm disappointed with D2. I'm angry with C9, and I'm going to resolve not to make the same mistake again. There's no room in this game for hiding in the corner. I will fight you magicwand, and I will trade blows until one of us gives in. I only half care which of one it is, because more importantly, I can't afford to turn this into a game that follows your momentum.
My Sparta wants its Freedom.

i expect below. after that i am looking for 'a' rather than 'b'
'b' is point oriented but imo 'a' is just as good. ofcourse c first.
