Michael Roiz: The Grandmaster Who Writes the Book
In modern chess, knowledge is power in the most literal sense: games are increasingly decided by who has prepared the opening more deeply at home. The players who map that territory — who work out the best moves and publish them — shape how everyone else plays. Michael Roiz is one of them: an Israeli grandmaster whose acclaimed opening books have become trusted references for serious players around the world.
A Strong Grandmaster
Michael Roiz was born in 1983 in the Soviet Union, in present-day Belarus, and was raised in Israel, where he developed into one of the country's strong grandmasters. He earned the title as a young man and competed successfully in international tournaments, holding his own against elite opposition and contributing to the Israeli national team. He was, by any measure, a fine practical player.

But Roiz's widest influence came through his writing. He became an author of opening repertoire books — detailed, rigorous guides that recommend and analyse complete systems for tournament players. Such books are only as good as the grandmaster behind them: they require not just strong play but the patience and honesty to work out the truth of a position and present it clearly.
Roiz's books earned a reputation for exactly that quality — depth, reliability, and the kind of analysis a competitive player can trust with their tournament results. To 'follow Roiz' on a given opening became, for many players, a sound and respected choice. In an age of chess engines, the human author who can organise and explain the machine's findings remains invaluable, and Roiz is among the best at it.
Why This Matters
Roiz matters because authorship is a form of influence that outlasts results. A grandmaster's tournament wins are eventually forgotten; a trusted opening book shapes the games of thousands of players for years. Through his writing, Roiz extended his understanding far beyond his own board, into the preparation of competitors he will never meet.
He matters, too, as part of a distinctly Israeli strength in chess scholarship. Alongside fellow grandmaster-authors like Boris Avrukh, Roiz helped make Israel a notable source of the opening theory that the global chess community relies on — proof that the country's contribution to the game runs not only through the players who win, but through the thinkers who explain how the game is won.
