B) 9...Nxd4 Warning: This is not such a great move despite this Geller game:- 10.Bxd4 e5 11.fxe5 dxe5 12.Bc5 (Bxe5 Qa5 favours black) Re8 13.Qxd8 Rxd8 14.0-0

In this position, Rf1 is a strong move. Perhaps Gellers opponent would have done better with it. The unpleasant threat is Be7. If Re1, then 0-0-0 is really comfortable for white. The way White played this, allows Rd2. It is useful to have the king still on e1!
