Beginners Corner 040514: Lesson: Always Look for Attacking Moves!

Analysis of our chess games doubles our fun!
White advantage (+)  or Black advantage (-) and all in tenths of a pawn increments  - according to Fritz.
1. e4    e5
2. d3   d6
3. Be2   g6
4.  Nc3    Bg7
5.  Nf3    f5
Voluntarily weakening Black’s kingside. White (+.8)
6. Bg5    Nf6
7. Bxf6?!   Qxf6
“To take is a mistake” as the pin is mightier than the capture. Advantage falls to (+.1)
8. Nd5    Qf7?
Black is allowing 9. Ng5 – giving White a strong move with tempo as Black would have to move the queen again. Qd8 looked ugly, but was fine.
9.  c3?!    O-O?
After White’s move the game was even. Black is still allowing Ng5. But White moves the same pawn one square – twice!
10.  c4?    c6
11.  Nc3    Be6?
Black had a (-.4) lead, but the last move now leaves the bishop in danger of being traded off if White sees that Ng5 move.
12. b3   f4
13. d4?   ……
Allowing 13.  ….   exd4, 14. Nxd4 c5 wins a piece! Instead, Black returns White’s advantage to (+.5).
13.  …..    Na6
14.  d5     cxd5
15.  cxd5?   Bg4
White still misses Ng5 for a full pawn positional equivalent lead instead of (+.5).
16.  Bxa6    bxa6
17.  Qd3    Rac8
18.  Rac1    Qb7
19.  O-O     Rc7
20.  Rc2     Rfc8
21.   Rfc1   …….

The game is EVEN here. Black has a choice of Bxf3 or Qb4 to keep it that way.
21.  ……    a5?
22.  Ng5!    Qb4
Finally White plays aggressively! Black didn’t need a5 before Qb4, so now the move is one move too slow. (+1.5)
23. Ne6   Bxe6
24.  dxe6   Bh6?
Now White has 25. e7!  Rxe7, 26. Nd5 with a fork of Black’s Queen and Rook. Black could play Re8, but Nd5 still is a killer with a (+3). But he not only misses it, but blunders.
25. f3??  ……
Instead of opening up the kingside, the move was h4 to stop all the back rank mate threats for Black. Now ….Qd4+! and White is in trouble with 26. Qxd4, exd4, 27. e7, Rxc3 28. Rxc3, dxc3, 29. Rxc3, Re8 and Black is leading (-2.7).
25. ……    Qb6+
26.  Kh1    Bf8?
If 26. …..Qe3 Black has a (-.5) lead to build on as White’s knight is pinned. Instead,
27. Nd5!    Rxc2
28. Rxc2     Rxc2
29. Qxc2    Qb5
White is up (+4.8) due to the advanced e-pawn, and goes on to win.
Black had chances, but White finally saw the aggressive knight moves in time.
