I looked at the book secret of chess tactics by mark dvoretsky and in pages
94-100 there is a game of Borkowski against nunn that is discussed
Nunn claimed after the game that 12...gxf5 could lead to better position for
black.
The book claims that 13.Nce4!! refutes 12...gxf5 and that the line
13.Nce4 fxe4 14.Nxe4 is winning for white.
I did not find a convinvcing line against 14...Nb4 or 14...Nc5
