{Waiting for Anderssen to arrive from Breslau, Paul Morphy enjoyed the delights of Paris - including the Opera House. During
The Marriage of Figaro he entertains his hosts with this elegant brilliancy, mating on the 17th move with his last two pieces!}
1.e4 e5 2.Nf3 d6 3.d4 Bg4
{Not yet in the Philidor Defense! After a few forced moves White gets a big jump in development.}
4.dxe5 Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6
{Seems natural, but Qe7 was necessary, as this game shows.}
7.Qb3 Qe7 8.Nc3
{Development, not material!}
8...c6 9.Bg5 b5
{Far too optimistic, given the congestion of the black pieces.}
10.Nxb5 cxb5 11.Bxb5+ Nbd7 12.O-O-O Rd8 13.Rxd7
{ Removing another defender.}
13...Rxd7 14.Rd1 Qe6
{Air at last - but now Morphy shows how simple a mate can be.}
15.Bxd7+ Nxd7 16.Qb8+ Nxb8 17.Rd8# 1-0
