The Queen's Gambit.
2...e6

Nd7
4.Nc3
Ngf6
5.Bf4
dxc4
6.e3
Nd5
Black menaces the Bishop. If White now took the Knight, Black's pawn on c4 would be defended and White's light-squared Bishop would be cramped.
7.Bxc4
White regains his pawn and continues developing.
7...Nxf4
8.exf4
Now Black has the Bishop pair and has fractured White's pawns, but at what cost in time! It took the Black Knight three moves to take the Bishop on f4, and now it's gone! White, on the other hand, spent every one of those moves developing. Now his time advantage is quite substantial.
8...Bd6
Attacking the pawn at f4.
9.g3
White calmly defends himself. Now Black's Bishop is "biting on granite" down the diagonal.
9...Nf6
10.0-0
White castles, secure in the knowledge that Black will never be able to dig his King out from under the mountain of pawns at h2, g3, f2, and f4.
10...0-0
11.Qe2
White connects Rooks and completes his development.
11...b6
Black plans to drop his Bishop on b7 and eventually penetrate the light squares around White's King down the long diagonal.
12.Rfd1
White centralizes his Rook opposite the Black Queen, a good idea in general.
12...Bb7
13.Rac1
a6
Thinking to expand at b5 with a gain of time.
14.Bd3!
White repositions his Bishop, removing the point of Black's idea and placing it on a more effective diagonal.
14...Bb4
15.Ne4
Threatening to capture the Knight on f6, when White could oppose Black's Bishop down the diagonal.
15...Qd5?
Black exerts pressure on the Knight at f3 through the Knight on e4, seeking to reduce the effect of White's capture at f6. But this is a mistake.
16.Nfg5!!
A superb reply. Suddenly, Black is in a pickle. White threatens to take the Knight on f6 with check, then take the pawn on h7 with check. After Black's King moves, White has a nifty retreat with his Bishop back down the diagonal to e4. This both defends against mate and skewers Black's Queen and Bishop, winning material.
16...Ne8
This awkward retreat meets White's immediate threat, but it leaves himself open to a new one.
17.Nxh7!
The Knight cannot be captured because White has a discovery at f6, winning the Queen.
17...f5
Black now threatens to capture the Knight on h7 for real, as well as menacing the Knight on e4.
18.Nhg5!
Taking the Rook works as well, but this is more stylish. Now if Black takes the Knight on e4, White takes back with his Bishop, winning material on b7 anyway. At this point, Black had had enough and decided to call it a day. 1-0
