CONCLUSIONS This is an unspectacular game which on the surface contains nothing really remarkable. The game can be broken down into the following stages • 12.Nxg6 creates a structural imbalance and gains the bishop pair for long−term chances • A general advance on the queenside−Gaining the a−file− Gaining the 7th rank and maintaining a rook on a7(32.Rba2)
