Meet David

Hi! I'm David, and together with John, I am thrilled to be able to bring you Chessable.

I have a personal background in computer science and games. Because of this, I have been involved in the social games industry for about 6 to 7 years. I had a chance to create games that reached millions of players around the world. A career highlight was when in one day we reached enough of an audience to fill a stadium the size of Camp Nou!

In the last few years, my focus has shifted towards Psychology and the human sciences, and as part of that, I completed a Master's Degree in the Psychology of Education (BPS) at Bristol University. I used this time to research about how learning occurs and how to make the most of it. I also integrated my interest in chess as much as I could to my coursework.

In fact, my dissertation was titled "Can implicit theories of intelligence and chess, together with deliberate practice, improve our understanding of expertise and expert performance?". My work received a grade of distinction and was recommended for publishing in a peer-reviewed journal by one of its previous Editors. I also hold a PGCert in Applied Psychology from the University of Liverpool.

How does this all apply to Chess? Well, chess has always been one of my passions, but in these last few years, I have taken it more seriously. Around 2013, I realised that the current way we learn chess openings is very inefficient. I watched hours of educational video content, read books, nothing stuck.

In 2013 I wrote Chessable as a very basic product for my own use. When I played my very first FIDE tournament game, I realised Chessable was working well. In my second game, I drew easily vs. a player rated 2,050 FIDE. Not bad for my debut in an official tournament!

It was at this point I considered the idea with more seriousness and decided to take it further by building a team around it, to improve the product and reach a wider audience so that everyone could benefit. Late 2015 I brought the idea to John, and the rest is now in front of you. I hope you like it.

Meet Simon

Hi, I'm Simon. I'm a front-end developer from Germany.

I like solving problems, and making things shiny! I'm very much intrigued by learning tools such as Chessable, and fun, engaging learning environments.

In the summer of 2016, I got the opportunity to start working for Chessable on a volunteer basis. Currently, I am extending my skills through an online front-end developer program designed by Google.

The work for Chessable combines my interests in web design, memory, and chess.

Meet John

Hey there - I'm John!

I am an International Master from Eagan, Minnesota who has been playing, studying, and teaching chess for over 20 years. In 2002 I won the National High School Chess Championship, and in 2006 I became an IM. After graduating in 2009 from the University of Texas-Dallas with a degree in Business Administration, I spent a brief time in law school before deciding to become a full-time chess teacher in 2011.

One of the most frequent questions I've received as a chess coach is "How do I go about studying chess openings?" Opening study is a popular and necessary aspect of chess improvement, but it was frustrating to tell students that there was no efficient "go-to" resource out there. Proper opening study requires both understanding and memorisation, and I was not aware of a single platform that offered this.

Enter Chessable. In late 2015, Chessable CEO David Kramaley contacted me about a site he had built to assist in his personal study of chess openings. I liked the concept, and since David and I both saw great potential in the idea, he invited me to join forces in an effort to make Chessable a premier, modern platform for learning chess openings. Moreover, we believe Chessable has application even beyond chess openings!

I hope you enjoy the site. Feel free to leave me any questions or feedback here on Chessable, or head on over to my YouTube page where I post daily instructive chess videos. Good luck with your chess improvement!

Meet Leon

Leon is an award-winning former national newspaper journalist who joined the Chessable team in January 2018. He is a devoted dad, a keen league player and secretary of Battersea Chess Club in London. In his last job for The Telegraph Leon broke almost every chess story that made mainstream news in the UK over the last few years. He has met most of the top players and, as an ex hack, he's still always on the look out for a good chess tale to tell. Leon is roughly 1600 Fide, a modest rating he blames on his son refusing to sleep.

Meet Jabe

Jabe Esguerra is an experienced blogger and internet marketer. His lifelong dream of having a “chess career” came true when he joined the Chessable team in June 2018.

No, he hasn’t gone pro, in case you’re wondering. Jabe only sports a 1600-ish online rating. Rather, he’s busy providing support to Chessable users and tasked with the extremely important task of converting print books into digital format.

Meet Daniel

Hi, I’m Daniel. I’m a Fide Master from South Africa. I have been playing tournament chess for over a decade, winning several national championships along the way, but one of the moments I’m most fond of is drawing against Garry Kasparov in a 2012 simul.

I first came across Chessable in August last year – I was dissatisfied with other chess training tools and was searching for something new. I was immediately impressed by Chessable’s simplicity, elegance and power. Since then, I decided to use Chessable for my own chess repertoires – gradually I imported my preparation and began training with it.

In December 2016, I decided to publish a portion of my repertoire as a public course. The reception by Chessable users was great! After conversing with David, I was offered a part-time post at Chessable with multiple responsibilities.

I hope you will join me on my quest to chess improvement with the help of Chessable!
