1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Bf5 5. Ng3 Bg6 6. h4 h6 7. Nf3 Nd7 8. h5 Bh7 9. Bd3 Bxd3 10. Qxd3 e6 11. Bf4 {Let's see one by one by one the moves and try to understand the reason behind them.White has 2 available plans for his bishop. The one is placing it at f4 to control the important e5 square and create problems for Black if he decides to castle on q-side.} 11... Qa5+ {Black's plan is to force the white bishop to retreat at d2.} 12. Bd2 {Practically forced. White doesn't want to exchange queens so soon and after 12.c3 he can't castle on q-side because of the threat on a2} 12... Qc7 {Black now prevents the white bishop from returning at f4 and q-side castling seems now safer.} 13. O-O-O {Q-side castling is white's main plan in this line since the rook has to stay on h1 to prevent early attacks on the potentially weak h5 and the mobilisation of Black's k-side pawns.} 13... O-O-O {Very few have tried k-side castling in this position and none of them twice. White has a ready dangerous attack with g4-g5.} 14. Ne4 {The kight is useless at g3 and will be sooner or later under attack after ...Bd6 so White re-centralises it to prevent ...Bd6 and prepare g3-Bf4 if possible.} 14... Ngf6 {Black immediately attacks the centralised knight.} 15. g3 {That move not only prepare Bf4, but also prevents Black from invading on f4.} 15... Nxe4 {The centralised Ne4 is far too annoying to be allowed to survive.Black exchanges it without any delay.} 16. Qxe4 Bd6 {One of the best squares for the bishop.The alternative was ...Be7with ...Bf6 following but Black usually wants to play Nf6 and keep h5
under pressure.} 17. c4 {As white wants to place his bishop on c3 , he can't
allow his important c-pawn to be locked on c2. You will see that c-pawn will play
an important role in the game.} 17... Nf6 {Very logical move that attacks the
queen andplaces the knight in a square that attacks h5 and makes d5 difficult.}
18. Qe2 {The best square for the queen and it will be soon clear why the queen
on e2 exerts an indirect pressure on Black's q-side.} 18... c5 {A must play move if Black wants to get any counterplay. Otherwise White will prepare d5 or c5 under favorable conditions for him.} 19. Bc3 {This is one of the 2 best
positions for the bishop and many consider it the best and they play directly
11.Bd2 which reaches the same position with both sides having gained a tempo.
Bc3 controls the important e5 and once d-pawn is advanced or exchanged, it
will exert pressure on Black's k-side and especially on g7.} 19... cxd4 20. Nxd4
{This isconsidered the best move as it creates the immediate "threat" Nb5
forcing Black to play a6 sooner or later. You will realise that a6 is a serious weakness and White will try to exploit it.} 20... a6 {This is a move Black would like to avoid, but it will be risky if he does as Nb5 will be a constant threat.} 21. Kb1 {White vacates c1 for the rook as soons as possible.} 21... Rd7 {Preparing the doubling of the rooks on d-file seems to be Black's best
fighting chance as in d-file lies most of Black's counterplay} 22. Rc1 Kb8 {It is
very risky for Black to leave his king on c-file as soon it will be a war zone.}
23. Nb3 {One of the 2 possible plans white has at his disposal for the knight.
Nb3 is certainly the most aggressive and the most risky while Nf3-Ne5 is more
quietand aims to achieve the usual favorable B vs N endgame.} 23... Qc6 {That is a very common placement of the queen as Black's counterplay lies also in the long light squared diagonal. From c6 the queen threatens to give a check on h1, forcing white to have always a rook on the 1st rank or give h5, in some cases invades to g2, in other cases supports ...e5-e4 or ...Ne4.} 24. Rh4 {Also a thematic move. The rook protects h5, doesn't allow ...Qe4 or ...Ne4, doesn't allow Rh1+ and can be tranferred to q-side through the 4th rank.} 24... Rhd8 {Both sides have played a model game placing their pieces in the best possible squares.} 25. c5 {That is one of the key moves when white plays Nb3 and Rh4. The pawn is well protected, Nb3 can play to a5 or d4 chasing Qc6 away and Rh4 can join the attack through the 4th rank. The downside of the move is that it surrenders the control of the important d5-square to Black.} 25... Bc7 26. Rc4 Qb5 27. g4 Rd5 28. c6 {The point!!!Soon the Black king will be in serious trouble.} 28... Rd1 29. Rxd1 Rxd1+ 30. Kc2 Rd6 31. Nd4 Qd5 {Black queen returns to h1-a8 diagonal.} 32. Rb4 {Qe2 now creates a lot of threats on a6. That is why it is important for white to have his queen on e2 when the c5-c6 attack is launched.} 32... Qe4+ {32...b5 was better although White would respond 33.Nxb5 retaining good attacking chances.} 33. Qxe4 Nxe4 34. Rxb7+ Kc8 35. Ra7 Bb6 36. Rxa6 Bxd4 {Here Black fails to understand the position. He should exchange the very dangerous Bc3 without much thinking.} 37. Ba5 {Threatening Ra8#} 37... Ba7 38. f3 Ng5 39. Rxa7 Rxc6+ 40. Bc3 {The bishop returns to c3 and it is obvious that Black will have problems on k-side too.} 40... g6 {Once more Black fails to understand the position. It was necessary to play 40...e5 stopping the thematic f4-g5 attack.} 41. f4 {The attack on q-side came to an end with the win of a pawn and one would expect that white will start advancing his connected "a" and "b" passed pawns but surprisingly the attack on k-side wins even quicker.} 41... Ne4 42. g5 hxg5 43. h6 {That very common endgame "trick" allows White to create
an outside passed pawn that many times has won the game.} 43... Nxc3 {Black
finally exchanges the bishop but it is too late.} 44. bxc3 Kb8 45. Rxf7 1-0
The following comments would not print out in the pgn, So I just decided to list them below:

favorable for him conditions.}
19. Bc3 {This is one of the 2 best positions for the bishop and many consider it the best and they play directly 11.Bd2 which reaches the same position with both sides having gained a tempo.
