Isildur1 and the week that changed online poker 17 years ago
Indeed, there must be a trick somewhere. First, the guy opens 6 tables and doesn't win. Then there is this "brb" moment where he shuts down 5 tables and start to focus on the last one. The pattern is similar with the other opponents, first he loses, then something happens, then he starts to destroy his opponent.
There is a pattern here. Maybe the guy has programmed a tool/helper that can learn from the playstyle of his opponent really quick (multiple tables at first), making them more predictable and modifying the stats accordingly. I don't know, but something is definitly happening somewhere in the process.
