This is a tricky point. It seems to me that if I answer with :w1: below, Black can descend at :b4: in sente and throw in at :b6:. If I connect after :b8:, I suffer from a potential shortage of liberties - :b10: and "a" would threaten to capture two/seven stones. If I do not connect, the ko at :b6: would threaten both to live and to trash my upper side. As a result, the solid connection looks better in this case.

Perhaps we should use triggers during the ko fight to make it go faster?

triggers: If H18, I will recapture the ko. If you fill the ko, I will play H18.
This was part of my plan going in, if Black did not prevent it. I have the impression that if Black fills the ko, I will gain sufficient compensation by cutting off the center stones. This may not be true since Black will have sente and can play to reduce my capture as much as possible. If Black responds at H18, I think White is much better off since Black will no longer have a safe eye on the top. This should help me in responding to future Black ko threats.

So here's the deal. I took his threat offer because this is really a huge ko and he will ignore almost anything, except maybe this:

Or other local threats like it. At the same time, he can just make threats that aren't as big as the ko and still make a profit. This threat is worth about 25 points, and after subtracting what he lost for starting the fight means he gained a little over 10 points in gote the way I see it. It's probably a little less, because I have this nice clamp later on:

Which should help reduce the middle. The move I just played aims at reducing the bottom to almost nothing, and hopefuly even capturing some stones depending on how he plays. To be honest this situation is pretty hard to read out, but some the ideal is:

I am going to respond on top. Mainly I feel that simply connecting is too passive. There are many ways for Black to continue locally and there are even more ways for Black to turn elsewhere and try to use the aji in this position later. Perhaps it would be better to connect solidly, but I have my pride! :blackeye:
