I had a lot to catch up on with IM John Bartholomew 2.5 years after his first visit to Perpetual Chess. Then,  as now, John is best known for his very popular Chess YouTube channel, and for being the co-founder of Chessable.com.   John has seen the company and his following continue to grow rapidly in the past few years, and as you may have heard, Chessable merged with GM Magnus Carlsen’s Play Magnus company in September of 2019. John also has recently released a large-scale  project, a Chessable video course , explaining the endgame classic, 100 Endgames You Must Know, and he even got to film a video testing the World Champion on the material from this vital chess book.  In our conversation, John gave some behind-the-scenes details on all of these exciting events. He also threw in lots of good chess improvement advice in reply to some good questions from listeners. Please read on for more details and timestamps.  If you aren’t seeing embedded hyperlinks in your podcast feed, you can find them on the podcast website here: https://www.perpetualchesspod.com/new-blog/2020/2/11/episode-164-im-john-bartholomew 0:00- Ways to interact with the Perpetual Chess Community include: Twitter, Perpetual Chess Facebook Group, and now, Perpetual Chess is sharing podcast clips on Instagram! https://www.instagram.com/perpetualchess/ 2:00- We begin by discussing John’s recent trip to Wijk an Zee in order to film a YouTube video with World Champion, GM Magnus Carlsen.
