After some analysis I think Black is plain lost after the decisive mistake
17...Kxf5 ?? e.g. 18...Bh6 19.Rhf1 Bf4 20.Rxf2 or 18...h5 19.Rhf1 Kg6 20.Rxf2
17...Ke7 looks very OK though 18.Nd6 Bh6+ 19.Kb1 Kf6 20.Rhf1 and now 20...Rf8
21.Rxf2 Nc6 22.Qc4 Kg7 as in Topalov-van Wely
or maybe also 20...Nc6 or even 20...Be3 might be satisfactory. But it's
definitely complicated.
Playing the Najdorf against Yace to expect 6.Be3 and 7.g4 is always a safe
bet:).
