Dortmund: el cazador cazado

[Event "45th Sparkassen Dortmund"] [Site "?"] [Date "2017.07.16"] [Round "2"] [White "Bluebaum, M."] [Black "Fedoseev, V."] [Result "1-0"] [ECO "D46"] [Annotator "GM Elshan Moradiabadi"] [PlyCount "61"] [EventDate "2017.??.??"] {Lori Greiner, one of the main characters of Shark Tank, is very proud of her talent in identifying whether a business idea is a 'hero or zero'. Well, I wish I had her sharp instinct in chess to realize what is going on with Fedoseev's tournaments. The aggressive young Russian star keeps dazzling and baffling me. After winning 'easily' against Kramnik, the Russian succumbed to his first defeat after an overly optimistic opening against host hero Matthias Bluebaum. } 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4.
