Knight's move approach.
It's been a while! I forgot just how much mess I was in here - actually, maybe a little less than I was thinking back then. I don't think that my lower right group can realistically be threatened too much- I can make a second eye at 15-4, which I'd forgotten about. It's still quite bad, but definitely can be made up with a fight, and likely can be made up without a fight and just proper judgement. Here goes!
I considered adding another move to either the left middle or right middle groups of mine, but everything is already nearly alive on the right (so play away from thickness demands that I play away). The left middle actually had quite nice shape - I can't see a way to cut it, and it's very much out in the center. Still, the slide is a big followup locally. Also a candidate is playing in the top right corner, but I want to have as many interesting areas of the game as possible to catch up, so I don't want to trade enclosures and make everything strong.
Looking over my comments I agree with almost everything I said - except that I needed to see his tactic here. I even mentioned it in my post for the response to the kick, which was the correct time to read out the sequence - but I failed to read out the sequence! In retrospect, I should have just gone for the good shape move, wand in general I should go for more good shape moves.
Speaking of good shape, I have tried out the bottom left large knight's move a few times during our break, and analyzed them with Lizzie. Since we're so far away from the original, and I never played a similar shape to this game, I figured it would be okay. Actually the first time I tried this large knight's thingy I forced a 6d to resign in 55 moves on WBaduk - everything went just as I planned it to go in this game
I think I'm 3-1 overall playing the large knight's move fuseki-thing so I definitely recommend trying it out, if you want to skip over the territory meta that's popular these days.
I expect him to back off small knight's as normal, which is one line away from the ladder potential in the center. Then I think I'm going to play 4-2 immediately in the bottom left. My plan is to try to stave off his attack on my approach stone by having a strong group already in the center. Maybe with some counterattack on a good day I'll be able to take the upper right a little extra efficiently.
