Volume 2 5k to 3d tesuji problems -
Tesuji appearing in joseki:

Where do I even start?
Capturing stones and winning capturing races: Really easy compared to what I was expecting. It's almost like a second volume of get strong at tesuji (Which I've completed 4 times over, so that might be a factor). There's also a bit of boost to my ego when the "solve at a glance = 1 dan" I can do in 10 seconds (Since I found the solution at a glance and had to read out the continuation) and the "Solve in 2 minutes = 2 kyu" slapping tesuji I solved in the same amount of time. Even the solve in 5 minutes = 5 kyu I got in probably 30 seconds when I realised the net would only turn into a simple squeeze if white had tried to escape.
Volume 7 300 opening and middle game problems 1d to 7d -
Chapter 1 is multiple choice and is mainly urgent before big. I got most of the answers correct, and the answers I did not get correct were usually second best with comments like "Normally, this move is above criticism, but in this situation...."
Chapter 2 is entitled flexibility in the opening and oh my god I fail at this section. I'll get maybe 40% of the ones I've attempted right, another 20% I get second best, and the others I just miss the mark completely. In some problems my first intuition was correct, and yet getting fancy and second guessing myself caused me to get a second best answer or even miss it completely. There are still some in this section that are a no brainer to me.
I still love the ideas I'm getting from thinking about why the right answer is the right one and see moves I wouldn't have thought to make before.
Before I begin chapter 3 I'd like to finish 501 opening problems since chapter 3 is not multiple choice.
