Now I see your mistake: you follow the evaluation of an engine in a position
where every body said the engines have little understanding.

The line you propose is fine, but after 13...Nb8 with the idea of Bd7 and Nc6
the position is only slightly better for white but open to a a dynamic play, so
Fritz could find a way to defend.

A much better situation then that of the game where the engine could not see
that after Qc7 the the a5 pawn was doomed and hence the engine evaluets the
position as still almost equal and avoids this line, but seeing that a5 will
fall this line is less evil imho.

After Qc7 taking in b5 is still possible but with Nxb5 you waste a tempo with
the queen.

By the way I guess Nxb5 with the idea of Bf4 and Nd6 is probably better then the
line computer suggest.

Franz
