6-10 draw, 9-14 loses

A. Lafferty Defense. Larry keen is one from not so many players today who continue to play this difficult defense. An interesting fact is that Don Lafferty who first introduced this defense in serious play, in his late career avoid it and played more conservative 8-11. Even though 14-17 doesn't lose a game, but it gives white a good scope and choice of couple very powerful lines.

B. My favor attack against Lafferty Defense. 28-24 also good enough and covered in Basic Checkers.

C. Ed Bruch and program "Wyllie" played here 5-9 into lost (program later drew the game with man down after my missing). See Sixth, SG-43, Pg. 324

D. See diagram #1. Mr. Keen missed here a draw 6-10.

[Event "TN 2010, Rd. 3, G1"]
[Date "March 6, 2010"]
[Black "Alex Moiseyev"]

I don't like to annotate games I lost. I always beleive that this is a winner privelegy. However for historical purpose and records, and also for forum readers fun I am givng this game here with short comment.

25-22? loses, 23-18 & 23-19 draw

A. GAYP opening. I wasn't very happy with such ballot drawing because expected that Justin with his long online experience must be familiar with lines of this opening. However his low practice in real ty's with strong players had an influence on his play and knowledges. Hey, if he did so well in this ty with so little PP knowledges, what should we expect when he learn something ?!

B. In first game Justin incidentally played here 9-14 which is more likely leads to white win. And so I did.

In the 2nd game I didn't know exactly what he knows here, but I was a bit afraid to play a classic 10-14. This move, 7-11, is not so good if meet properly. However, it certainly gives black some chances if white don't play it accurately. Ron King played 7-11 against me in our 2005 3-moves World Championship and game ended with draw and some original play.

C. Good but not the best. Indeed 18-15 is correct way to meet 7-11 keeping an advantage.

D. 31-26 also sounds but in both cases black has good game.

E. Loses ! See diagram #3. Amazing position. It is hard to beleive that such a natural move already loses the game. 23-18 or 23-19 was OK for draw. WOW !

Games with Michael Holmes and Frank Davis will be posted later.

32-28 draw, 23-18? loses

A. Should I say at least that my feelings were mixed when we selected this unevenful, restricted GAYP ballot with limited scope ?! :lol:

B. This is very conservative solid reply after which often enough peauceful agreement among strong players is on the way.

C. 25-22 instead 30-26 also playable.

D. Nothing wrong yet with this move, but white slight opening advantage is disappeared now. 25-22 was correct way to play keeping small pressure on black position.

E. See diagram #4. During the game here, at one time Michael put his hand close to man on 21 and it looked like he just wanted to play 21-17?? 9x18, 23x14,11-15 etc BW. This didn't bother me much because I thought it's just a fooling around :lol: However later I changed my mind !

Michael nerviously took his hand away of this posien man and spent another 10-15 minutes thinking on his move. I immediately realised now that he really didn't see a loss for 21-17 and find it at last second!

Probably this fact was a small psychological disaster and shot for Michael and had serious influence on his feelings.

In position on diagram white still has a draw 32-28, but Michael took a wrong way.

F. Loses immediately.

G. White are already in lost, however some play still remains. I, personally, would try here 18-15, 12-16, 15-11, 16-20, 11-7, 2x11, 10-6 etc with man down play but some compensation and hopes.

===========================================================================

[Event "TN 2010, RD6, G2"]
[Date "March 6, 2010"]
[Black "Alex Moiseyev"]
[White "Frank Davis"]
[Result "2-0"]

Frank is very interesting player with his own style and character. He knows some publish play and has good cross-aboard skills. It is always not an easy task for me to play with players like Frank, because they can make very strong moves and at the same time - miss things. This usually require for me to pay attention to the rest of game, be careful and do not overplay position.

1. 9-13 24-20 2. 11-15 (A) 22-17 (B) 3. 13x22 25x11 4. 8x15 21-17 5. 5-9 17-13 6. 4-8 29-25 7. 8-11 27-24 8. 9-14 24-19 (C) 9. 15x24 28x19 10. 10-15 (D) 19x10 11. 6x15 13-9 (E) 12. 15-19 23x16 13. 12x19 25-22 14. 11-15 9-5 (F) 15. 2-6 (G) 20-16 16. 14-18 22-17 17. 19-24 17-13 18. 15-19 16-12 (H) 19. 18-23 26-22 20. 7-11 22-18 21. 6-10 31-26 (I) 22. 11-16 13-9 23. 24-27 9-6 24. 27-31 26-22 25. 31-26 18-14 26. 26x17 14x7 27. 1x10 7-2 28. 10-15 (J) Black Wins

9-5? loses, 26-23 draw ............ 16-12* draw, 32-27? loses

A. Guess where and when I played this opening last time and who was my opponent ? Of course Frank Davis (!) at Alabama State Open ty in November 2009 :lol:

B. In our first game with Frank I tried for variety 23-18, 8-11, 18-14, 10x17, 21x14, 4-8, 27-23 ?! which leaded into original cross aboard game ended with draw.

C. Hence, he played this suspicious move again as he did at AL 2009! This year, after the game, he promised me that he will never play this move !

D. Perhaps the best way to meet this trade.

E. Interesting and completely sound move. In AL 2009 Frank played 25-21 instead 13-9 and drewed the game, but I think I missed a win later.

F. This move starts a nice comedy of errors where both of us made mistakes. See diagram #5. 26-23 was correct way to play it. During the game I expected this move and wanted to play 7-11, but this is only unfortunate draw after 9-5*, 3-8 and now either 31-27 or 32-28 drew the game!

G. It is my turn now to screw things :lol: This move is missing a very clever win by 7-10*, 20-16, 14-18*, 22-17, 19-23*, 26x19, 15x24, 32-28, 24-27, 31x24, 18-23 etc Black Win

Couple years before, in AL 2008 I won both games against Frank with pitches. When we started our round this year, I asked him before we selected ballot: "Should I pitch something today ?" In fact I had a perfect chance to accomplish my promise, but failed !

H. See diagram #6. During and after the game I thought and told Frank and others that 16-12 loses the game and 32-27 should be a draw. Wrong again ! Look at diagram. It is an amazing fact that 32-27 here is a complete lost. I am leaving this verdict here for forum readers and let them discover this on their own ... for their fun and enjoyment.

16-12 as played by Frank was still OK for draw.

I.As I wrote in Sixth, it is not important who made first mistake, and it is not important how many mistakes made each player. An important thing is - who made a last mistake ! It is proved by Kingsrow program that white had a draw here after 13-9.

J. What a game !!!

Alex,

I am enjoying going over these games you have posted.
Jonathan and I had 10-14, 23-19, 6-10 opening and Jonathan went man down on purpose on both sides. He said " Here I go again when he did it in the 2nd game" Very aggressive talented young player. I may post those games later after I digest your posted games some more.

Your friend,
Wayne

Wayne, in first game your both assumptions were correct and either 17-14 or 19-15 should win. In second game it was more fun ... :lol:

Wayne Gober

A) 8. 9-13? loses for red, 2-7 was correct PP

B) 8. ... 24-19? missed win for white, 18-14 was correct.

C) 9. 10-15? loses for red, 2-7 was correct returning back on PP

D) 10. ... 21-17? missed win for white (18-14 wins)

E) 11. 8-12? loses for red and it was a last chance and time in this game when red can drew it. After then white didn't miss anything. 2-7 or 1-6 instead 8-12 was OK, keeping trade on 10 in hands if white moves on 14.
