Eljanov's Icelandic Masterpiece

Pavel Eljanov is having the probably best chess year of his live. At least this far. He made it to the semi-finals of the World Cup, lifted his rating again above the 2750 mark and above all, played a lot of great games. A game with a creative player like Grzegorz Gajewski of Poland suggests an interesting, colorful battle. This game in round eight of ETCC indeed became a candidate of a best game in Reykjavik:
A game that I liked (ChessBase 13)
