1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. d3 h6 5. O-O d6

{

Everything is going fine so far.  Both sides are concentrating

on developing their pieces, controlling the center,  and

getting their kings into safety (with the exception of black's

prophylactic...h6).

}

6. Nc3

{

The last move is certainly playable and logical, but should

lead to an equal game.  6. c3 would keep more of the pieces

on the board and retain greater flexibility, and hence

generate more winning chances for white than the text. 

Grandmasters and masters alike, if they assay the Guicco Piano

(3. Bc4) will almost invariably choose 6. c3.

}

6... Nf6 7. Be3 Nd4

{

A good move by black.  This prevents 8. d4 by white, which

is both line-opening and space grabbing.  In addition, black

can now boot any white piece that tries to plant itself at

d5 by playing his pawn to c6, and last but not least, white

will have to remove his dark squared bishop to get rid of

the black knight on d4, since 8. Nxd4?? exd4 would lose a piece.

}

8. Na4 Bg4

{

Good.  This completes development while pinning white's

knight on f3 to the white queen.  8. ... Bg4 also shows

that black is paying attention, as white was threatening

to win a pawn with 9. Nxc5 dxc5 10. Nxe5.

}

9. Bxd4 Bxd4 10. c3 Bb6 11. Nxb6

{

?! Since black's bishop wasn't going anywhere, there was

no need to rush this capture.  Instead, white has a chance

to break the pin by playing 11 Qb3!?.  If black takes white's

knight with ...Bxf3, then white replies Bxf7+ (check!) K moves

and gxf3.  It's true white's pawns are doubled, but they

reinforce white's center, plus of course white has the pawn

plus.  And at any convenient time, white can eliminate that

bishop on b6.

}

11... axb6 12. Re1 O-O 13. Re3 c6 14. d4 b5 15. Bb3 Qd7

{

Playable, but both 15. ... Nd7 and 15. ... Qe7 were worthy

alternatives, since the queen would be preserved.  A queen

trade goes into an endgame where black has doubled-pawns,

which may favor white slightly.

}

16. dxe5 Bxf3 17. Qxf3 dxe5 18. Rd1 Qe7

{

A good place for the queen.  It reinforces black's pawns

on e5 and f7, gets the queen out of danger, and leaves open

the option to post the queen to c5, if convenient.

}

19. Qf5

{

considering the black knight guards d7, this move does nothing. 

White may have been worried by ...Nd7-c5, but a3 would be a

better response.  a3 would allow the white Bishiop to move

(now that it isn't tied down), which could allow Bc2 in some

lines to defend the e-pawn.  Also, the general rule is: keep

pawns the opposite color of your bishop, if possible.

}

19... Rfd8 20. Red3 c5

{

! A nice move which takes advantage of white's dubious Qf5. 

Clearly, white cannot try to win a pawn with 21. Rxd8 Rxd8

22. Rxd8 Qxd8 23. Qxe5?? as 23. ... c4 24. Bc2 Qd2 threatens

the bishop and mate, and there is no way to defend against

both, and white has no perpetual checks.

}

21. c4

{

If white has to play this (which he does), then clearly

something went wrong.  after black plays ...b4, then white's

c-pawn is a potential target, d4 is opened up as a potential

outpost for the black pieces, and the pawn blocks white's

own light squared bishop.  Notice that if white had played

a3 earlier, then in response to ...c5 he could have simply

played Bc2, with an even game.

}

21... b4 22. Rxd8+ Rxd8 23. Rxd8+ Qxd8 24. Qxe5 Qd2

{

! Now due to the inaccuracy of white's play, black will

enter a superior ending because of black's more mobile knight.

}

25. g3 Qe1+ 26. Kg2 Qxe4+ 27. Qxe4 Nxe4 28. Bc2 Nd6 29. b3

{

Putting yet another pawn on a light square.  29. Bd3 was

to be recommended.

}

29... f6 30. f4 b5 31. cxb5

{

? Very bad.  Allows the black knight great activity and outposts

(c3 an d4).  Far superior was 31. Bd3 bxc4 32. Bxc4+! Nxc4 33. bxc4 =

}

31... Nxb5 32. Bd3 Nc3 33. Kf3 Kf7

{

Good.  It's important the black king get into the game as soon

as possible.  Besides, white's a-pawn isn't going anywhere.

}

34. Ke3 Nxa2 35. Bc4+ Ke7 36. Ke4 Nc3+ 37. Kf5 Nd1 38. Ke4

{

Dubious.  This allows black to consilidate.  Better was

39. Kg6 Ne3 40. Bd3 (Kxg7?? 40. ... Nxc4 wins for black) Kf8

41. h3, and it's hard to see how black will make progress.

}

38... Kd6 39. g4 g6 40. h4 Nc3+ 41. Kf3 Nd5 42. Ke4 Nb6 43. Kd3

{

?? 43. Bf7 still offers white chances to draw.  For example,

if 43. ... c4 44. bxc4 b3 45. c5+ Kxc5 46. Bxb3 trades off

the queenside, and 43. ... g5 44. fxg5 fxg5 45. hxg5 hxg5

46. Kf5, white picks up the g-pawn, with a draw the likely

result.  The text should lose immediately, as 43. ... Nxc4

wins on the spot.

}

43... g5 44. hxg5 hxg5 45. fxg5 fxg5 46. Bg8 Ke5 47. Bf7 Nd7

48. Kc4 Kd6 49. Bh5 Ne5+ 50. Kb5 Kd5 51. Ka4 Kd4

{

Now black's superior king + knight will decide the game.

67. Kf4 Kc3

{

Black is clearly winning here...only a blunder by black

could lose/draw this.
