I went a bit further into the "100 Endings you need to know"-book, for some 70 minutes. Still interesting, really (well written). I actually did a lesson together with my son. This not only increases his endgame abilities as well, but also serves as a good repetition and deepening for myself.
In addition, I did some online blitz games: I was trying to practice my new opening with black. But guess what - I actually didn´t get a single position with my new opening... 8-/
(It´s my mum´s birthday today - so this will be it for today! Tomorrow, I have enough time to get back to my PAT and my new opening!)
