I need to make sure Black doesn't make two eyes there. If he does, my enclosed group will probably die. So I need to find a move that prevents Black from living locally.
There are two moves I am considering, a and b.
$$c

a limits the eyespace but lets Black make strong shape and play a lot of forcing moves.
b spoils black shape, but lets Black play b to expand his eye space.
Let's start with a.

I don't really see how to kill Black after this. Do you?
Here's another

Black lives.
And another

Black lives again after c.
Well, I don't know if Black is good at life and death. He might die anyway but I don't want to wager the whole game on this.
As for b, here's what might happen.

If Black lives like this, my enclosed group will surely die.
This compromise might be a good option.

Black steals points from me but at least I don't die.
Perhaps this is what'll happen, although I doubt it.

A good system naturally covers all corner cases without further effort.

if he is afraid of dying and let black go free..he doesnt deserve to give him 8 stones.

all he has to do is cutoff the lifeline then i dont think black can live.

If Black lives, I will make two eyes too.
For instance

I might also play at a instead of
. I think Black has a weakness there.
I wish I could kill it but my surrounding groups are too weak. Perhaps I should have played the d5-d3 sequence earlier.

You need to consider at least this
. Your
has no effect on the corner at all.

So I was thinking of playing at M2 but that would make life easy for Black. Moreover, I will have to take gote to make life for my own group. That is not good enough.
The move I decided to play is risky but it makes life difficult for Black. Black cannot make an eye at H2.
I have a feeling it will turn into a capturing race. His corner will probably suffer too.
Finally, Black might make a mistake in the center after I play at a. If he falters there, things will be easy for me.

I first thought of playing
$$Wc

but the cut worried me a little.
I can of course prevent the cut this way
$$Wc

but my shape here becomes really awful.
I could have played like this

which is what could have happened if Black had played at

But I think my move in the game is better.

This is what may happen next. Black's lacking two eyes.
