I have no idea why Spike played 20.Na3, backing off a nicely-placed Knight. Maybe Spike thought it could eventually bring it over to the Kingside? And CM9_R1 agrees with the draw assessment, and sees this as the entire line: 20.Nxc7 Rxa4 21.Bxf6 Qxf6 22.Qxa4 Bxc7 23.d5 Qxf3+ 24.Rg2 e3 25.dxc6 h5 26.fxe3 Qf1+ 27.Rg2 Qf3+ etc.... jm
