After threatening for more than two years, I broke down last week and upgraded my computer. It was long over due. With a new, bigger, and I hope better machine, it was also time to move into the 21st century regards my chess engine. After five or six years of service, the old reliable Chessmaster 9000 is gone replaced by the super-strong Deep Rybka. GM Har-Zvi told me many months ago this Rybka beast is by far the best software around. Today's game is my first analysis using Rybka. The software is easy to use, and if you have a newer computer with lots of RAM, it is a good tool.
Rybka came into my hand through the good offices of my teammate on the Geezers, Michael Mockler. He had a version that did not work with his current computer, and we were able to make a trade. My thanks to Michael. This Rybka thing works well.

CDCL Match Geezers v Albany
Schenectady Chess Club
05.27.2010
1.d4 d5
2.Nf3 Nf6
3.c4 c6
4.Nc3 dxc4
5.e4 b5
6.e5 Nd5
7.Ne4?
The almost universal choice of the 2600+ set is 7 a4. The text is premature as shown in Czebe,A v Utasi,T, Budapest 1991 where Black won in 30 moves. Play continued; 7 Ne4,Bf5; 8 Ng3, Bg4; 9 Bd2, e6; 10 a3, Nd7; 11 Ne4, Qb6; 12 Bc3, a5; 13 Qd2, Be7; and Black has his pawn safely in hand with extra space on the Q-side.
7.. e6
Unfortunately, I did not know enough chess culture to understand what was going on in this opening. Better is 7..., Bf5.
8.Be2 Bb7
9.0–0 Nd7
10.Nfg5?! ..
An interesting try that should lead to problems. Again it is a premature action.
10... g6?!
Safer is 10.., Be7.
11.Bg4 h6
12.Nxe6 fxe6
13.Bxe6 Qh4?
Better is 13..., Qb6. I was proud of the text but had not given enough thought to whither goes the Queen when she gets pushed?
14.f4 0–0–0
15.g3 Qe7
16.Nd6+ Kc7?
Better is 16,.. Kb8; not letting White capture the pawn on b5 with check in some lines. Black is not worried about the Knight going to f7 forking the Rooks because he takes the Be6 and the Knight will not get out alive, and Black will have three(!) minor pieces for a Rook and two pawns. True enough the White K-side pawns are threatening, however Black can get in an early .., c6-c5; when the White King will have worries aplenty.
17.f5 g5
Much better is 17,.. gxf5; and Black is beginning to get on top of the game.
18.Bxd5 cxd5
19.Nxb5+ Kb8
20.Qa4 a6
21.Nd6,..
21., Nb6??
One query because the move is wrong and another because I missed the correct idea. What are we taught about sacrificial attacks? Give back the material to eliminate the pressure! Best here is 21.., Nxe5!; 22 Nxb7, Qxb7; 23 dxe5?, Bc5+; 24 Kg2, d4+; and Black’s game is completely won according to Deep Rybka. Honestly, the idea of returning material to open a winning attack just did not occur to me. After the game both Jon Leisner and Peter thought there was small hope for Black from about move 13. Apparently my good friends did not have the right idea about the position either.
22.Qa5 Qc7
23.Nxb7 Kxb7
24.Bd2 Qc6
25.a4 Ka7
White has had a small edge for the last few moves. This move starts my downward slide. It was accelerated by the mistaken conviction that my game was bad. The correct assessment is Black can make a fight of it.
26.Rfc1,..
Rybka likes 26 f6, as better try for White.
26.., Be7?
The best move is 26..., Qd7; holding back b2-b4.
27.b4 Rhf8?
This loses. 27..., Nd7; Keeps the fight going after 28 b5, Qb6; 29 Qc3, g4. I must confess the move 29..., g4; is something I don’t believe would see. White has an edge in this line, but it is not clearly winning. With the text move I seemed to have lost all notion of what was going on in the position. It was another case where my opponent was in deep time trouble, just seconds left and I played poorly. A strange thing but not unheard of; your opponent's time trouble brings out the worst in your game.
28.b5 Qc8
29.f6 Bxf6
30.exf6 Rxf6
31.Bb4 Qg4
32.Be7 1–0
I deserve a couple of dope-slaps at least for the bad play, particularly at the end of this game.
