I have said this in a few comments in responses to various people. In 2018 I was ill for half the year and recovering for the second half. I am still in a worse state than exiting 2017. It has slowed us down a lot, as have other things. Life, basically.
But things are moving ahead and we are finishing a lot of books at the moment. Kotov – The Science of Strategy is going to the printer next week. So is Boris Avrukh’s – Grandmaster Repertoire 2B, the final book in the 1.d4 Saga. It will be a big book with 29 chapters.
Colin will return from holiday next week and put up some excerpts once the books are uploaded to the printer. Meanwhile I have a screen shot for you.

Sorry to hear you were so ill. Glad you are getting better.
I was almost killed by C. diff colitis in 2013 so I can commiserate.
@Jeff Hall
Thank you. I had some respiratory infection. Very nasty. Just plain bad luck.
It sounds like you were suffering from Negis Refusies Topublishes Repertoiris. A horrific condition which is spreading rapidly worldwide!
If Colin is unable to for unknown reasons, I volunteer to create the excerpts. Just send me the raw material 😉
