Ne5+ Nxe5 13.Qxd4 f6 14.Nxc3 White has a winning position due to the exposed} 8. d5 {An instructive mistake since White wishes to develop with gain of tempo. By locking the center White keeps his own pieces out of the attack. 8.dxe5 Nxe4 9. Bd5 Nc5 10.Ng5 Qe7 would leave Black better developed.} 8... Ne7 9.
