I'm tempted to take the ko, but I'm not sure how this would end (white 7 at e.g. a or b):

It looks like living is not enough. I need to live with two groups, or kill his dragon. It is hard to tell how the game will go. I estimate about a 50% chance of winning.

I have tried and tried to read this, but it seems I always find a new variant. Therefore I admit that reading this position is beyond my ability. It is starting to look bleak, however.

The other option, of course, is to retake the ko, but according to my (insufficient) reading it seems like a worse choice:

It looks like I can't live on the bottom, but capturing is now sente so maybe that is enough. I'll probably seal in the to[ group, but I also have some really big weaknesses in the bottom left. I doubt I will have time to fix any of that though. I guess jumping into the corner is an option if the approach stone is attacked.

I'm a bit surprised he chose to end the ko now. If I have read correctly (probably not), I can kill his N9-group and thus save my N12-group, which I think is an acceptable end result.

Here we go. I am still behind, but I might be able to pull through somehow.

Hmm, will he be able to kill me? I don't know, but it looks bad. In any case, I couldn't find a better response.
