Studying Master Games

One problem I find when looking through master games is not understanding some of the moves - as in this example:

1.e5...c5
2.Nf3...d6
3.d4...cxd4
4.Nxd4...Nf6
5.Nc3...a6
6.Be2...e5
7.Nb3...Be7
8.0-0...0-0
9.Kh1...b5
10.Nd5!...Nxd5
11.Qxd5...Ra7
12.Be3...Be6

Can anyone explain the reason behind whites move: 9.Kh1

The game is the first game shown in the introduction to: "Pawn Structure Chess" by Andrew Soltis and is the game Kuzmin-Groszpeter, Kusadasi 1990

The complete game is here: http://www.chessgames.com/perl/chessgame?gid=1274497

I would guess for a later f4... could be a waiting move to see what variation black has planned. I see some moves in master games that dont make sense until later. How does the game proceed?

Yes I see..so this was to prepare for the later f4...which was played on move 15 and in the book is shown 15.f4!
Full game below:
[White "Gennadi Kuzmin"]

If you want to know the ideas behind an opening look at a dedicated book on that subject not a "clip" from the internet. That 1. e5 should be 1. e4

If you are interested in having a look at other master games explained:
