Robert Ris: "I have an in-depth look at the 23-move miniature from the game Yakubboev–Demchenko. In a relatively quiet line of the Queen's Gambit Accepted, White sacrificed his bishop on f7 as early as move 8!
The idea itself is not new and, theoretically speaking, still fine for Black, but it was enough to catch his opponent by surprise. Possibly Demchenko mixed up the move order, and so Black ended up in a lost position already by move 12."
Exercise: How should Black respond to White's threats?
