`  ::Not from Wang Yue, who lost last night in the FIDE Grand Prix 2008-2009. As for Tiviakov, it seems he wrote to Chessbase himself! On a Dec 4 item, Chessbase wrote: ``Addendum: we have been informed by GM Sergey Tiviakov that from 28.10.2004 until 28.09.2005 he played 110 games (normal FIDE controls, no rapid) and didn't lose any. ``Of course, my opponents were not all very strong,`` he writes, ``but they did include Ivanchuk, Aronian, Radjabov, Carlsen, Dreev, etc. So my record can still be compared with that of Wang Yue, for example.```` So while I'm sure Tiviakov wouldn't lie about it, I still think a database check would be nice.   `
