[7...Nf6
8.Bg2
Nc6
is the usual move order here]
8.Nb3
Be7
Preparing d6 [8...Nf6
9.Bg2
transposes to main line]
9.Bg2
[9.f4
stops Ne5, followed by 10. Bg2. However, I didn't regard Ne5-c4 as a dangerous threat.]
9...Ne5
10.0-0
d6
[10...Nc4
is met by 11. Bc1 followed by Nd4 and b3]
11.Nd4!
Activating the Knight and at the same time preparing b3, a4

d5?
Black probably missed 19.Bf4! [Correct was 18...Nd7
19.c4
where White has a slight edge]
19.Bf4!
Now Black is forced to play e5, after which his Q-side collapses

I decided to give up the pawn eliminating Black's counter-play
25...Rb8

28.Rfe1
White is clearly better
28...c5
29.Qc3
[29.Ra5
Re6
and Black is holding on]
29...h5?!
creates an additional weakness
30.Re5
c4
[30...Rc8
31.Bh3
]
31.bxc4
[31.Ra4
felt like an even stronger move, yet weakening the first rank seemed dangerous]

32.Rae1
Rb1
33.Bf3
Rxe1+
34.Rxe1
Rc8
It seems as Black almost equalized, but
35.Rd1!
holds onto the extra Pawn

36.Rd8+
]
36.Kg2
Qf5
37.Rd4
Qg5
38.Qd3
Qa5
39.Bd5
aiming directly at the King; White's pieces start the offensive
39...Re8
40.Rf4
with the idea of Rxf6 and Qg6+, mating
40...Qa1
[40...Qb6
41.c5!
Qd8
(41...Qxc5
42.Rxf6!
and etc.) 42.c4
and White is dominating]
41.c3

42.Qd4
[42.Qg6
is met by 42...Re7
]
42...Re1
43.Qc5

It turns out that Black really has no threats along the first rank
44...Qxc3
45.Qxf7+

46.Rf5
Kh6
47.Bf3!
simple and strong
