The Modern Arkhangelsk Defence (or Modern Archangel Defence) ("ECO" C78) is a refinement of the regular Arkhangelsk Defence by incorporating ideas similar to the Møller Defence. Black normally does not fianchetto the Queen's bishop, which would transpose to regular Arkhangelsk setups, but plays ...Bg4 to increase the pressure against White's pawn centre. White's main continuation is 7.a4 after which Black responds with the typical move 7...Rb8 reaching the starting point of this highly complex variation. Another line is the more traditional 7.c3 d6 8.d4 and after 8...Bb6 Black's position is fine. 8...exd4 occurred in Löwenthal–Morphy, London 1859, which seems to be the first time this variation was ever played. Fabiano Caruana is one of the most notable players of this variation, employing it in the Candidates Tournament 2020.
