It looks like that CM8000 is the best player in the wourld in this postion.After
his line 21.Nb3 Qe5 22.Kb1! the normal Nc5 is weak.
Shredder5 give +0,92 for white.

13.01	17:05 	+0.92 	23.Sd4 Se4 24.Lh4 Tc5 25.Ka2 Sef6 26.b4 Tc7 27.Lxf6 Dxf6
28.Dh3 Lc8 29.Sb5 Txe3 (127.290.733) 124.1
 14.01	48:07 	+0.92 	23.Sd4 Se4 24.Lh4 g6 25.Ka2 Sc5 26.Lf2 a6 27.Dh3 Se6
28.Sxe6 Txe6 29.Td4 Kh7 30.f4 Kh8 (342.189.762) 118.5

So Shredder is in the mode to sacrifice a pawn with 22...b5.
Looks very attractive for white.
