This is one of White's more ambitious tries in the Queen's Gambit Accepted. Black needs to keep an eye on the big center.

10.0-0-0
The position is quite double-edged. White has a clear lead in development, but his King might be exposed on the queenside.
10...Qb6?!
Forcing Queens off -- but since this also leaves Black with damaged pawns, White can be assured of some advantage.
10...Qa5!?
deserves consideration.

Now White is two pawns up, but he has to worry about his weak pawns on the queenside.

In this pure Rook and pawn ending, White's extra material gives him decent winning chances.
32...g4
33.Rb4

34.Kb2

35.a4
Ra6
36.Kb3
Now the King defends the pawn at a4, so White's Rook really is attacking the Black pawn at b7.
36...b6
37.Kc4
White threatens Kb5 followed by Kxb6 with an easy win.
37...Ra5
Black prevents White's King from coming forward.
38.Kd3
White now uses his King to block Black's e-pawn.
38...Kf5
39.c4
Ra8
Black would be glad to see more pawns come off the board since that would make it easier for him to draw. White, who has the extra pawn, keeps things complicated.
40.Kc3
Ra7
41.Kb3
Now White's Rook can come to b5 without leaving the a-pawn undefended.
41...Ra6
42.Rb5
Ke4
43.Kb4
Ra8
Finally Black tires of babysitting the pawn. In any event, White was threatening Rd5 followed by Kb5, so Black could not hold everything indefinitely.
44.Rxb6
Kf3
Now Black wants to run with the e-pawn as fast as possible.
45.Rf6+
Kg2
46.Re6
Black is going to win both of White's kingside pawns; White is going to win the Black e-pawn and then give up his Rook for the g-pawn. If White's timing is right, the White King and two pawns will then overwhelm Black's Rook.
46...Kxh2
47.Rxe5
Kxg3
Now we have a two-against-one contest. The problem, from Black's point of view, is that if each side gives up his Rook for one of the enemy pawns, White will still have a pawn left.

There are many ways for White to win here, but one of them is simplest for a human to find and play.

Cutting off the King -- the only move that makes any sense for a normal human being.
