Nc3 c5 11. dxc5 dxc5 {With a symmetric pawn structure resulting this might look safe for Black but in fact gives White the advantage as his pieces are more actively placed and a7, c7, and d6 all become target squares.} (11... bxc5 {was the most combative way of playing with quite a dynamic game in prospect.}) (11... Nxc5 {was the most solid way of playing} 12. Rfd1 Nce4 $11 (12... Qb8 $11)) 12. Rad1 Qc8 13.
