Played by Dominguez before against Glek. We also saw Kasparov win with this variation against Shirov. It seems that this quiet g3 has more sting on a long term than one would think. After 0-0-0 black has a clear plan: counterplay on the queen flank. In this line it seems hard to decide what to do. Future games will give a more exact evaluation of this rare move

10...Nxd4
[10...Qe7 Ftacnik The novelty after less frequent move 10.g3, Shirov is defending against attack and reserves the option to exploit the c4 weakness with the help of Nb6 move. 11.0-0-0 (11.Bg2 Ftacnik 11...Nb6 xc4) 11...Nb6 12.Nb3 Bxe3 13.Qxe3 Bd7 14.Kb1 Rfc8 (14...f6 Ftacnik 15.exf6 Qxf6 16.Bb5!
