This week we are joined by Chris Callahan, who is the Community Organizer of LiChess.org. Lichess is a community supported, free, open-source, ad- and tracker-free chess site which plays host to over 5 million chess games per day. Back in 2017, I interviewed its founder, Thibault Duplessis, so it was past time to catch up on all that is new with this great site. It has been especially important during the past year as online chess has surged in popularity. We discussed everything from how they dealt with a huge traffic surge, to their capabilities in the area of cheating detection. We talked about the viability of their current business plan as well as  their future plans. Chris also delved a bit into his own chess background, and shared his unique perspective on scholastic chess teaching and chess improvement. It was fun to catch up with him and to learn more about this website on which so many of us enjoy playing on a daily basis.
