1. e4 e5 2. Bc4
Bishop Opening

 
2... Nf6 3. Nf3
?!

 
3... d6 4. d4
transposed into Petroff Defense

 
4... Nc6 5. dxe5 dxe5 6. Qxd8+ Nxd8 7. O-O Bd6 8. Bg5
Idea behind this move is to capture either f6 knight to double pawn or d8 knight and after KxB, Black cannot castle.

 
8... Be6
Exchanging the bishops for White is useless.

 
9. Bb5+ Nd7
Reason bhind white bishops on b5 and g5 was also to make black move f6 and c6 as then black knights will not find good squars.

 
10. Nc3 c6 11. Rfd1
! if PxB RxB and Black got double pawns.

 
11... Bc7 12. Be2 f6 13. Be3 O-O
Although black knights are not on right places however fortunately Black's minor pieces have good control on d-file.

 
14. Nh4
Going to f5. If BxN PxB White got double pawns but Black gave one of his bishop. A dubios decision, however still thinking ... as it worked in future because it cleared the way of f3 pawn.

 
14... Nf7 15. Rd3
White has no hurry to move the knight to f5.

 
15... Nb6 16. Rad1 Rad8
if 16 ... Nc4 Bc1

 
17. Rd3xd8 Rxd8 18. Rxd8+ Bxd8
What a beautiful position, all minor pieces no any major.

 
19. Bxb6
!? this move is actually "future deciding" move.

 
19... Bxb6 20. Na4
White gave up a2 pawn voluntary.

 
20... Bxa2 21. Nxb6 axb6 22. b3
Now Black got double pawn and his bishop is trapped.

 
22... g6 23. Kf1
Someone has to go to prisoned bishop to kill.

 
23... Nd6 24. f3
Bd3 was bad.

 
24... b5
?? This move costed the game to Black, if Black played c5 and c4 direct he could escape his bishop, not only his bishop would be free but also he would get queen side pawn majorty and possilbly win the game. So looking to this positon White's 12. Bxb6 was not good decision, but as you see it is not easy to calculate/predict so further, specially when simple pawn move can cost the game. So lesson is "When you move analyse it as further as you can otherwise you can simply lose even by a simple innocent pawn move."

 
25. Ke1
Due to b5 White got time

 
25... c5 26. Kd2 c4 27. Kc3
King on right time at right place.
