Mega Database 2023 — Chessbase

In the cluttered office of disgraced former chess prodigy Viktor Volkov, the 2023 edition of the ChessBase Mega Database sat like a loaded weapon. Two years ago, Viktor had been a grandmaster on the rise. Then came the accusation: using an engine in a crucial tournament match. Stripped of his title, he retreated to a Berlin basement, surviving on instant coffee and resentment.

Someone had injected a fake game under his name. Stripped of his title, he retreated to a

His heart pounded. The database wasn’t just a record. It was a weapon. Someone had poisoned the well—inserting fake losses into his historical record to create a statistical case for cheating.
