About John Bartholomew
John Bartholomew is an American International Master, chess educator, and co-founder of Chessiverse. He earned the IM title in 2009 and over the next decade became one of the most recognisable instructors on YouTube, where his channel emphasises practical understanding over rote memorisation.
His Chess Fundamentals video series introduced a generation of online improvers to disciplined opening play, endgame technique, and the kind of slow, careful evaluation that separates strong club players from casual ones. On Chessable, his Comprehensive Scandinavian course remains one of the platform's most-recommended opening repertoires.
Beyond his individual content, John has been deeply involved in chess education infrastructure as a Chessiverse co-founder and a frequent collaborator with other educators. His teaching style is steady, plain-spoken, and rooted in helping players build durable fundamentals rather than chasing the latest opening trends.
The Comprehensive Scandinavian
John's flagship contribution to chess education is the Scandinavian Defence (1.e4 d5). His Chessable course on the line, The Comprehensive Scandinavian, is one of the most recommended Black repertoires for ambitious club players, and the same material is also available on Chessiverse as The Comprehensive Scandinavian by IM John Bartholomew. Whether you study it on Chessable or on Chessiverse, the underlying repertoire is the same: a fighting, theoretically grounded answer to 1.e4 designed to give Black equal chances out of the opening.
How his Chessiverse bot plays
John's Chessiverse bot is calibrated to 2434 Elo, putting it firmly in IM territory. It favours the Queen's Gambit and Italian Game with White and the Scandinavian Defence and Slav with Black, mirroring the calm, principled repertoire that anchors his teaching content.
