'14 ,,,e2' is the wasted move. After 14 ...Nxc5 instead, posing a
minimal sacrifice, the Black e3-pawn is still there to consider and may get
support soon from Rook. Http://www.chessgames.com/perl/chessgame?gid=1034110.
After that improved 14 ...Nxc5, any 15 Nd6 as really done, loses the Queen of course.
If 14 ...Nxc5 15 Nf6+ Bxf6, and King has enough of an outlet square. The original '14
...e2' is at first spectacular-looking but it's where Black goes wrong.
