Yesterday I finished making a new DB consisting of about 350,000 correspondence games which I think will be an even bigger help in my CC games. I can search opening lines that have been played by strong CC players. This has an advantage of telling me what lines have been successful plus I know that they have in all likelihood been engine checked. I checked a couple of my current CC games that are in the opening stage and here’s what I found:
After the following moves where I am playing Black: 1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.b3 Nc6 6.Bb2 Bd6 7.0–0 0–0
Fritz’ opening book shows a result of +4 -5 =2 and my database of CC games with at least one player rated over 2200 results: +9 - 8 =22, so the chances are about equal and a draw wouldn’t be unexpected.
On the other hand in the following game where I am also playing Black, after the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bg5 e6 7.Qd2 Be7 8.0–0–0 0–0
The Fritz book shows +25 -11 =15 and my new database with both players rated over 2400 results are not good either: +20 -7 =16, so it looks like I’m going to have an uphill battle in this one!
A final example where I am White: 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4 cxd4 8.Qxg7 Rg8 9.Qxh7 Qc7
After 9.Qxh7 Fritz’ opening book shows only two moves for Black 9…Nbc6 and 9…Qa5 with results of +2 -0 =1; not much help. My DB gives a different picture because after 9…Qc7, which isn’t given in the Fritz book, a search of the diagrammed position where both players were rated over 2400 shows +11 -1 =11, so that’s very encouraging.
Hopefully, this new DB will help me avoid inferior lines and bring better results. We’ll see.
