Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 c5 7. Bc4 Bg7 8. Ne2 O-O 9. O-O Nd7 {The real neo-classic centre is not formed, for Black has still to exchange on d4. He continues to postponed this pawn trade, so we can speak of a sort of enlarge neo-classic centre} 10. a4 $2 {This works out poorly} (10. Bg5 h6 11. Be3 { White will win an important tempo with Qd2}) 10... Qc7 {If White has chosen the correct move Bg5, then he could now have played Rc1 with good chances} 11. Ba2 {So White has had to lose a tempo; it is now clear taht Black has a very satisfactory game} 11... b6 12. Be3 Ba6 13. Re1 Rad8 { Thematic pressure against d4} 14.
