I agree that Nxc4 is a mistake but I am not so sure that Crafty11.19 could get a
win against the best defence that Rebel did not show in the game.

25...b5 was probably a mistake and also later 26...Qxb5 27.Nxc4 Rxc4 28.Rxa7 Nb6
is needed for example 29.Rc7 R8xc7 30.dxc7 Qc5 31.Rxc4 Nxc4 32.Qe4 Nb6 33.Qb7 f6
34.Qxb6 and white still has to work to translate the material advantage to a
win.
