This line is not convincing.
Black has many alternatives.

Deep Fritz's scores at depth 13 for some other options (the scores from black
point of view):

1...Bf5(0.63) 1...Bxd3( 0.38) 1...Bg6(0.16) 1...Nxd3(0.00) are some of them.

There are also a lot of alternatives in later moves.

White has to demonbsttrate a win against all these options in order to convince
me that Ng5 is winning.
