@FVitelli is 100% secret account of Ding. He played 4. h3 in this game lichess.org/JorsyKUh/black before this happened in world championship (and many other games vs same opponent, also in 4.h3). The most insane thing is that position of today's game (Bg5-h4) has exactly happened in his game vs @opqrstuv lichess.org/RQTnjMR6 - (opqrstuv is rated 2700-2800 in other time controls, GM level). Other games vs @opqrstuv are usually in Ruy Lopez or English, where both white and black show GM quality of play. For me that's obvious, opqrstuv is definitely some Ding second who played with him (Rapport). There were many games between @opqrstuv and @FVitelli. Why would 2800 play some random 1400-1500? It's obvious. They are training games between Ding and Rapport.
Ding's prep is now in danger.
