17-14 Tyne

[Ed Gilbert]

I expanded all the black moves after 10-15 21-17 9-13 17-14 using kingsrow/10pc with the automated book generator. The results are in a new book10 that can be downloaded from my website. The book shows database draws for 6-9, 6-10, 11-16, and 15-18. Probably this is no surprise to anyone. Most or all of these are published to draw and are shown as probable draws in the larger kingsrow opening book on all of the ballots. Nevertheless, this book10 play can be useful because it shows how black can always force play into a position where kingsrow can see a database draw on search of no longer than a couple of minutes. I'm not sure if 6-10 has been published to draw or not. I remember reading a discussion about it in the ACF Bulletin a few years ago, but I don't remember if any conclusion was reached.

I'm not sure if 6-10 has been published to draw or not. I remember reading a discussion about it in the ACF Bulletin a few years ago, but I don't remember if any conclusion was reached.

I think in published play 6-10 was considered as N. Banks loss with 23-18* as a winning move. Then, to the best of my knowedlges (I am writing this now without any book or board in front) ... 10-17 25-21 1-6 21-14 6-10 29-25 10-17 25-21 2-6 21-14 6-10 14-9* etc

After 6-10 23-18 10-17 25-21 other red continuations were tried occasionly without much success.

I also consider 6-9 defense in this opening as very weak after 24-19 15-24 (9-18 19-10* 7-14 22-15 11-18 26-22 etc White strong) 28-19 9-18 22-15* White strong etc I have references to this play in SIXTH

It would be a lot of fun to see, how 6-10 drew the game

Regards,

Hi Alex,

I think in published play 6-10 was considered as N. Banks loss with 23-18* as a winning move. Then, to the best of my knowedlges (I am writing this now without any book or board in front) ... 10-17 25-21 1-6 21-14 6-10 29-25 10-17 25-21 2-6 21-14 6-10 14-9* etcAlex

From book10, after N. Banks went 25-21, then only 11-16 draws. 2-6 is a loss.

I also consider 6-9 defense in this opening as very weak after 24-19 15-24 (9-18 19-10* 7-14 22-15 11-18 26-22 etc White strong) 28-19 9-18 22-15* White strong etc I have references to this play in SIXTH

From book10:
1. 10-15 21-17 2. 9-13 17-14 3. 6-9 24-19 4. 15x24 28x19 5. 9x18 22x15 6. 11x18 23x14 7. 1-6 27-23 8. 8-11 23-18 9. 11-16 26-23 10. 6-9 25-22 11. 2-6 29-25 draw.
