Opera Game

Morphy vs. Allies,

Paris Opera, 1858

Often called the "Opera Game", Paul Morphy's informal masterpiece played against the Duke of Brunswick / Count Isouard is the first complete game shown to many beginning + intermediate players.
It illustrates the value of development, centralization + king safety, but most important, it's the perfectly concise game to illustrate the beauty of chess art itself

In the game Paul Morphy played as WHITE,

but i will show now just the first NINE moves of the game,

guess the rest by yourself, how Morphy finished the match:

1.e4 e5 2.Nf3 d6 3.d4 Bg4 {This is a weak move already.--Fischer} 4.dxe5 Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6 7.Qb3 Qe7 8.Nc3 c6 9.Bg5 {Black is in what's like a zugzwang position here. He can't develop the [Queen's] knight because the pawn is hanging, the bishop is blocked because of the Queen.--Fischer} b5 10.???

So dears, in this current position of the chess board,

what exactly WHITE plays next + how BLACK respons?

Hint: From the tenth move to the knockout WHITE gives even a two sacrifices...
