[A new move? 11.Nxe5, 11.Na5 and 11.Qa5 have been played before]

12.dxe5 Be6 13.e4?!

[Fritz prefers 13.Rb1, 13.Qb3 or 13.Qa4 with a slight advantage for white]

13...dxe4 14.Bxe4 Qa5 15.Qe2 Rac8 16.Qb2 b6 17.Rfe1?!

[Fritz suggests that giving up the c-pawn with 17.c4 is the best chance to maintain equality. Now Charles methodically dismantles the White position]

[23.Qf1 Rxc3 24.Re3 is better, but Black is still winning]

23...Bd5 24.Rg1

[Or 24.Rxd5 Nxd5 25.Be4 Qxc3 26.Qxc3 Nxc3-+]
