Game Analysis--Newshutz v Dobbs

I have been trying to make a video of the game that led to the position in my last post.

My allergies have been getting in the way, and the audio is full of my throat clearings and other disgusting congestion noises. I don't want to pay for a video editor program, and I haven't gotten the free ones to work, yet.

Anyway, I have been going over that game so much, I am going to move on to another for my first video, and I will post my analysis of Newshutz v Dobbs from the 2010 Region VI open. I used Fritz to help create this analysis.

1. Nf3  d5 
2. g3   c6 
3. Bg2  Nd7 
4. O-O 
Instead of O-O I could have transposed into some kind of Catalan or Slav with d4 and c4
4...    e6 
This is a very cautious but solid move, setting up the QGD pawn wedge. A more challenging move would have been 4...e5, or to develop the bishop with Bf5 or Bg4 before playing e6
5. d3   Bc5 
6. c3 
I think this move is too cautious. Better would have been e4
6...    Ngf6 
Now I have to do more preparation to play e4
7. Nbd2 O-O 
8. e4   dxe4 
9. dxe4 e5
With this trade opening up the d-file and e5 mirroring the pawn structure supporting the d-file. I looked to gain space on the queen side. I am hoping to draw his pawn off of c6, or to get my own pawn to c5 to create an outpost at d5 or d6.
10. Qc2  Re8 
11. b4   Bb6 
12. Nc4  Bc7 
13. Bg5 
This is a mistake. all it does is provoke h6, which in some cases can become a weakness, but also removes the possibility of my knight going to g5. It works out ok for me in the end, but was unnecessary.
13...    h6 
14. Be3 
And this is probably not the right square for the bishop, but I wanted to connect my rooks for contesting the d-file. There is no urgency to contesting the d-file, because  there are no invasion points for either player along the d-file, I could bring the bishop to d2, leaving e3 open for my knight on c4
14...    b6 
15. a4 
I was too focused on gaining space on the queenside and missed his next move. I should have moved Rfd1 to avoid the pin.
15...    Ba6
16. Nfd2 Ng4 
17. Rfd1 Nxe3 
18. Nxe3 Qe7 
19. Rab1 
I did this to support b5, but I missed that if cxb5 it opens up d5 for my knight. This is odd, because I
am prepareing b5 to dislodge c6 to open up d5 for my knight. (19. b5 cxb5 20. Nd5 Qd8 21. Bf1 and I regain my pawn. Bb7 22. axb5)  I am moving to fast and not considering the full ramifications.
19...    Nf6 
20. c4 
I am bringing up more support for b5, and opening up the option to do c5, but I am giving up contesting d4 (20. b5 cxb5 21. axb5 Bb7 +=)
20...    Rad8 
21. b5   Bb7 
22. bxc6 Bxc6 
23. Nd5  Qd6 
24. Nf1  Ba8 
I missed a tactical shot here.

25. Nfe3 
I have a discovered attack set up, and I did not take advantage. (25. Nxb6! Qe6 26. Nxa8 Rxa8 27.Ne3+-)
25...     Qc6 
26. Rdc1  Bd6?
This mistake allows me to disrupt his kingside pawns and makes that provoking of h6 on move 13 look good!
27. Nxf6+ gxf6 
28. Nd5   Bc5 
29. Bh3   Qd6 
30. Qd2   Bxd5 
31. cxd5 
I do not want to retake with the e-pawn as that releases his e-pawn (31. exd5? e4 32. Re1 Qe5 -+)
31...     Qf8
32. a5 
I should have doubled my rooks on the c-file and began infiltrating on the light squares. I thought I was only marginally ahead, and I was playing for a draw at this point. (32. Qe2 Re7 )
32...     Qg7 
33. axb6  axb6 
34. Qe2   Qg5 
35. Bg4   Rd6 
36. h4    Qg7 
37. Kg2   Re7?
This is a fatal weakening of the back rank, and I missed a winning move here. I think he was worried about me shifting my rooks to the a file and taking the seventh rank.

38. Ra1
(38.Rxc5! Qf8 (38... bxc5 39. Rb8+ Qf8) 39. Rc4) and I am up a piece with a dominating initiative.
38...    Qf8 
39. Ra4  Qe8 
40. Rca1 Bd4 
41. R1a2 Rd8 
42. Ra7  Rxa7 
43. Rxa7 b5 
44. Be6??
I made this move too quickly (see last blog post)
44...    Bxa7  0-1
