1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 a6 6.Be2 d6 Navara has chosen a clever move order. 7.0-0 Nf6 8.Be3 Be7 9.f4 0-0 10.Qe1 Inaccuracy enabling black to equalise quickly. Black's move order without Qc7 has been important. 10...Nxd4 11.Bxd4 b5 12.a3 Bb7 13.Qg3 g6 Navara already knew this in the last century. [13...Bc6 Transposing to normal lines.
