I think the first error was 9...Qc7, it is probaly necessary to "concede"
something and take in b5 (I admit I havent checked if there is any tactics that
prevent cxb5).

But a more severe error is 14...Bd6 this wastes a lot of time. I would go for
14...g6 followed by Nh5 anf f5 or for 14...Ne8 followed by f5.

Many of the moves from 15 on show the lack of a plan. A tragic wait and see
approach.
E.g. 22...Nf6 was again bad and f5 a possible alternative. Still I feel black is
already lost here.

White important moves are silent moves: 13.h3 takes the g4 square away from any
attempt of Ng4-f5.
Further 18.Rb2 to overprotect f2 as suggested on ChessBase site. I don't know if
this induces fritz to dislike f5, but if this is the case then poor fritz!
