(A) Forms Deo's Goat Getter and the diagram. I was curious about this and let Cornell chew on it at an average of one move per minute which normally looked ahead at least 20 some moves at 60,000 or better positions per second and sometimes many more!!
(B) This seems to me like a fairly logical way of finishing Deo's idea to a clean draw. I would imagine there are several ways to draw this with perhaps a remote possibility of a winning chance for White should he go to sleep. However, the real idea here is to pull something new on your opponent to wear him down for the next game and I might add, a good strategy which was strongly driven home to me in my match with Ron King. In my first match ever against Derek Oldbury for the World's GAYP Title, Deo treated me like I was the champion and was extremely nice in every way. This perhaps helped me gain confidence and I barely managed to eke out a win by the very close score of 1-0-23. I liked Deo in all respects and he was a very fine checker player. I really do not know, but somehow I got the idea he was glad I won. Don Lafferty - October 26, 1996
Don Lafferty is the author of above. Many of us feel, he is the best Grandmaster in the world. His many friends have included the finest players in the world, since his teen age years when he began to play serious checkers. The likes of Dr. Marion Tinsley, Edwin F. Hunt, Walter Hellman,( Former world champions, all) Elbert Lowder and many others, have had their influence on Don Lafferty, and surely have contributed to his Grandmaster status. Earlier in 1996 he played for the world's 3-mv title against champion-Ron King, in Barbados. He did not win the title, but remains the undefeated challenger, having tied the champion 5-5 with 30 draws.
Don LaffertyHis many titles, including 5 American Titles, ( Winner of the National Tournament in 1986 and 1994 and 3 GAYP U.S. opens, and former GAYP world champion) attest to his tremendous knowledge of published play and crossboard skills. We are greatly pleased to present the above play, by Mr. Lafferty is shown on the right, doing some analysis at the 1986 Ty. Regarding the 1986 National Tournament, Lafferty's friend and mentor, Former World champion, Dr. Marion F. Tinsley, commented: "You won that tournament with a "Square Jaw", and referred to the photo as the Square Jaw photo.

Derek Oldbury Deo, ( Derek E. Oldbury ) passed away in 1994, as the world champion. These two Grandmaster's tangled many times across the board, including their world's title match for the GAYP title-won by Lafferty by the close score of 1-0-and 19 draws.
Derek was born a paraplegic, and lived his 71 years in a wheel chair. He overcame it all, to accomplish his dreams. He published his classic "The Complete Encyclopedia of Checkers", ( 6 volumes )and won the world's title in 1991. Derek was from Devon, England. He will always be missed.


THE JAYWALKER

June 23, 1997

I now have World Champion Checkers (WCC) which is the much improved update of Cornell. So, I let it analyze the position to the right. The position comes from
11-16, 24-19, 8-11, 22-18, 4-8, 26-22, 16-20, 30-26, 11-16, 22-17, 10-14, 17-10, 6-24, 28-19, 7-10, 26-22, 10-14, 19-15(Z), 16-19, 23-16, 14-23, 27-18, 12-19, 15-11, 8-15, 18-11, 9-13, 22-17, 13-22, 25-18, 5-9, 31-26, 1-6(X), 29-25(Y), 6-10, 21-17, 9-13, 25-22, 20-24, 18-15, 24-28, 15-6, 2-9, 32-27, 28-32, 27-23, 19-24, 23-18, 24-27, 17-14, 27-31, 14-5, 13-17, 22-13, 31- 8 Red Wins. WCC *

(X) Forms diagram on the right. In my previous write up of this position, WCC played 1-5 and White was able to draw by Dick Fortman's suggestion of 18-15. I asked the critics if Red had a better move here as the position looked fishy to me. Albert "Tuck" Tucker comes to our rescue by suggestioning this fine move and he found only Red wins after. Apparently WCC found only Red wins too. So, I present the above trunk and note Y and await the critics comments. If indeed 1-6 does win and it looks like it to me, then this corrects pp and is a fine example of Tuck's keen eye for excellent moves. This kind of move (1-6) reminds one of a Marion Tinsley touch as he was always developing 1-6 or 32-27 to obtain optimal development. Thank you Tuck!

(Y) 21-17, 9-13, 17-14, 13-17, 18-15, 3-7, 32-28, 7-16, 15-11, 20-24, 26-23, 19-26, 28-12, 26-30, 12-8, 30-26, 8-3, 17-21 etc Red Wins. WCC

(Z) If 1-6 at note X wins, then it seems the only draw given in pp is by 22-17 here.

9-13, 23-19, 11-16, 19-15, 10-19, 24-15, 16-19

(A1) ) In the past I have wondered about this position more than once as pp seemed to indicate this is a poor move and 22-17 is preferred. However, it seems White has more choice than pp admits and perhaps it is not so bad after all. If the following figures by WCC are correct, then pp needs to be updated. Critics comments are most welcome.

(A2) Forms the diagram of an interesting position. Hellman vs. Chamblee diagram

(C) Chamblee continued 27-23, 7-10, 23-16, 12-19, 24-20 etc to lose. However, instead of 24-20, the annotator Jack Cox commented there is no hope after this. Jack offered 15-11, 14-23, 24-15, 10-19, 21-17, 8-15, 28-24 etc to draw and WCC concurs finding this quickly.

[D] 31-26, 10-19, 24-15, 12-16, 26-22, 16-19, 23-16, 14-32, 21-17, 8-12, 16-11, 32-27, 17-14, 9-18, 11-7, 2-11, 15-8, 4-11, 22-8, 12-16, 8-3, 27-23, 25-22, 16-20, 3-7, 23-19, 7-11, 20-24, 11-16, 19-12, 28-19, 6-10, 22-18, 10-14, 18-9, 5-14, 13-9 draws WCC. Presented by Don Lafferty August 12, 1997

CC. Lafferty is referring to our game, where I jumped 10-28, to lock the pieces. I had been planning on winning this. After 10-28, 17-1, 28-32, 1-6, 22-26, and the touch of the Grandmaster with 27-24!, 20-27, and 6-2. Now 7-10 or cut 7-11 does not matter. I cut 7-11, 16-7, 3-10, and 23-18 holds the piece for the king to regain. Drawn. AL Lyman-Don Lafferty.

(D) 14-9, 28-32, 27-24, 20-27, 9-6, 32-28, 6-2, 7-11, 16-7, 27-31, 13-9, 31-26, 9-6, 26-22, 6-1, 10-15, 1-5, 3-10, 5-9, 15-19, 2-6, 28-24(or 10-15 RW), 6-15, 24-28 etc Red Wins by 1st Position.

(E) Dick recently mentioned he did not now see why this was bad. It is deceptive and there is more to this ending than I have shown. Perhaps a draw will be found yet. All play by WCC and DML



ALMA - DON LAFFERTY VS MARION TINSLEY - Phone game early 1990's. I would like to mention Marion had just come in from work and no doubt was tired, but he never complained as he was always ready to think about checkers. Throughout the game we were laughing and talking as usual and he was playing blindfolded! He seemingly played this game with ease - which is just one example of his truly amazing abilities. 11-15, 23-19, 8-11, 22-17, 3-8, 25-22, 11-16, 26-23, 7-11, 30-26, 15-18, 22-15, 11-18, 23-7, 16-30, 7-3, 8-11(A), 17-13, 11-16, 24-20, 16-19, 27-24, 19-23, 31-26, 23-27, 32-23, 9-14, 29-25, 14-17, 21-14, 30-21, 14-10, 6-15, 24-19, 15-24, 28-19, 21-17, 3-7, 2-11, 19-16 draw agreed.

(A) Forms the diagram to the right. This was an experiment on my part. It seems to be a good move and as far as I know new to pp. After the game, Marion thanked me for drawing his attention to this move. We never did return to this, so I let World Champion Checkers (WCC) analyze this game at two minutes per move. Below is the interesting WCC analysis. Game Analysis is a outstanding new WCC feature the previous version, Cornell, did not have. Gil Dodgen is to be highly praised for this feature and the many other fine additions and new features making WCC the very best computer checker program available. WCC is a must for any player regardless of his level of play.

Analysis is by WCC with a little help from me. Don Lafferty.

(A) Forms the diagram. A favorite of Jim Morrison played recently with Richard Hallett in the 1997 US Open GAYP TY. There seems to be scant play on this natural move.diagram

(B) Once suggested by Asa Long as good Red reply. I think Jim was expecting the natural reply, 6-9, which he has had good luck against in the past.

(C) 32-28, 8-11, 26-23, 18-22, 23-18, 6-9, 21-17, 22-25, 29-22, 11-16 (It is hard to imagine, but Jim resigned at this point - at least the record shows this.), 20-11, 7-16, 18-11, 9-25, 17-14, 25-30, 14-10, 5-9(G), 10-7, 9-13, 7-3, 30-25, 11-8, 4-11, 3-8, 11-15, 27-23, 13-17, 8-11, 17-22, 11-18, 25-29, 18-25, 29-22, 24-19, 22-17, 19-15, 17-14, 15-11, 14-10, 11-8, 10-15, 8-3, 2-6, 3-7, 6-9, 7-2 etc draws.

(D) 15-18, 32-27, 6-10, 17-13(E), 10-17, 23-14, 12-16, 20-11, 8-15, 14-9, 5-14, 13-9, 4-8, 9-5, 7-10, 5-1, 2-6, 1-5, 6-9, 24-19, 15-24, 27-20, 10-15, 20-16, 8-12, 16-11, 12-16, 11-7, 16-20, 7-2, 15-19, 29-25, 22-29, 26-23, 19-26, 31-6, 14-18 draws.

(E) 24-19, 8-11, 19-16, 12-19, 23-16, 10-15, 26-23, 22-25, 29-22, 18-25, 16-12, 25-30, 12-8, 11-16, 20-11, 7-16, 8-3, 15-19, 23-18, 30-25, 18-15, 25-22, 17-13, 22-18, 15-11, 18-9, 13-6, 2-9, 3-7, 9-13, 7-10, 16-20, 27-23, 19-26, 31-22, 20-24, 10-14, 24-27, 22-18 etc perhaps the easier way to draw.

(G) 30-25, 10-7, 25-22, 7-3, 22-18, 24-20, 18-15, 11-7(H), 2-11, 3-8 then (5-9, 27-23, 9-14, 31-27 etc) or (16-19, 31-26, 5-9, 27-23 etc) both being easy draws.

(H) When Newell Banks reached this position against Walter Hellman in the 21st US Open, he blundered with the unbelievable move 3-7 to easily lose which was no doubt due to fatigue. Newell and Walter had already had a marathon game and Newell was 71 years old. It is easy for me to understand getting so tired one just can not think as I have been there many times in the last two years. I hope you enjoy this write up. If you spot errors, please send to me so I can correct this. Don Lafferty, Sept 30, 1997
****************************

Additional play and notes by your Webmaster.
This mid-game is very popular an very important, as it comes up from several openings and has been played into countless times.
1. 9-13, 24-20, 10-14, 28-24, 5-9, 22-17, 13-22, 26-10, 7-14, 25-22, 1-5 same as DC game.
2. Or, 10-14, 24-20, 6-10, 22-18, 10-15, as in the Hellman-Banks game in 58 NT, mentioned in Note-H.
3. Or 9-13, 24-20, 5-9, 28-24, 10-14, 22-17 etc same as No. 1.
In the 1948 Brownwood, Tx. Nat. Ty., Tinsley-Chamblee had 10-14, 24-20, 11-15x, 22-18, 15-22, 26-10, 6-15, 28-24, 8-11, 21-17, 15-18, 23-14, 9-18, 17-14, 1-6, 30-26, 3-8, (6-9 draws Sheares Handbook) 32-28, 6-9 to a draw. Instead of 32-28, it seems 25-21 and 11-15 would be on the DC you sent.
The ending you sent is standard. Pretty game. From the DC run-up, I don't find any pp on the 17-14, 21-17 line. Another point. Instead of the standard 3-7 at 17th move, a pet "cook" of the famed computer "Chinook" is 11-15, taken vs. Tinsley in their 1990 match, and also vs. Markusic in 90 Nt. After 11-15 Tinsley cut 26-22 to dr. Instead he might have played 17-14, and if 3-7 (nothing better) then 21-17 would have been back on your analyzed play. AL The complete games, Chinook-Tinsley 1990, and Tinsley-Chamblee 1948. Chinook-Tinsley 1990. 9-14, 22-18, 5-9, 24-22, 10-15, 28-24, 15-22, 26-10, 7-14, 25-22, 1-5, 22-17, 14-18, 23-14, 9-18, 30-26, 11-15, (Chinooks cook) 26-22, 18-25, 29-22, 3-7, 27-23, 8-11, ( 7-10 is the standard pub. ply, but Chinook had been put in "aggressive mode.") 23-19, 6-10-A, 31-27-B, 5-9, 17-13, 9-14, 13-9, 14-18, 21-17, 18-25, 17-14, 10-17, 19-3, 11-15, 27-23, 25-30, 32-28, 30-26, 23-19, 15-18, 3-8, 4-11, 19-16, 12-19, 24-8. Drawn. Time-2 hours.
A. Against Markusic, played about 2 weeks earlier, Chinook varied here with 7-10, after which 17-14, 10-26, 19-1, 26-30, 24-19, 30-25, 21-17, 25-22, 17-13, 22-18, 1-6 etc. to a Draw.
B. At this point, Dick Fortman annotating the Chinook-Tinsley game, had these comments with the following play: "Being cautious." 17-14 offers more promise and was considered by Tinsley, then: 10-26, 19-3, 26-30, 3-8, 11-15, 8-11, 15-18, and then Tinsley said: "Here I saw 11-15, 18-22, 15-18, 30-25 was only a phantom, so I rejected this line and went for the clear cut draw."

Drawn.

"Don Lafferty continues to show important play on his page. Lines that are truly meaningful to all levels of players, and commonly played mid-game landings, invariably showing new twists and kinks -where some of us might have thought they were "solved" or exhausted of new play. In each and every game, Don shows things, previously unknown to the checker fraternity. His Grandmaster status, and play, continues to be a most welcome addition to our site." Webmaster-AL Lyman.

Don Lafferty (Red) vs Alex Moiseyev (White) a zone game Oct. 1997

9-14(AA), 22-17(BB), 11-15, 25-22, 8-11, 23-19, 6-9(A), 17-13, 2-6, 27-23(B), 14-18, 23-14, 9-25, 29-22, 4-8, 22-17, 15-18, 26-23(C), 18-27, 32-23, 11-15, 30-26, 8-11, 26-22, 5-9, 31-26, 1-5(D), 24-20(E), 15-24, 28-19, 11-15, 19-16, 12-19, 23-16, 15-19, 22-18, 19-24, 16-11, 7-16, 20-11, 24-27, 26-23, 27-31, 23-19, 31-26, 17-14, 10-17, 21-14, 26-23, 19-15(F), 23-19, 14-10, 19-16, 10-1, 16-7, 13-6, 7-2 a pretty Red Win.
(AA) The Double Corner and a favorite of mine to try to get away from the 11-15 lines, the overwhelming favorites of almost everyone.

(BB) This is a fine reply and usually leads to the Souter or Pioneer and thwarts my effort of avoiding 11-15 lines.

(A) Forms the Souter which Asa Long once commented is a good old time tricky game.

(B) 25-22 is usual and this was new to me. However, there is much published play on it.

(C) Marion Tinsley and I once arrived at this position from the Nailor! Thus 11-15, 23-19, 8-11, 26-23, 9-14 (to try to work up a line different than the usual play as we then had no idea this led to pp from the Souter), 22-17, 6-9, 17-13, 2-6, 25-22, 14-18, 23-14, 9-25, 29-22, 4-8, 22-17, 15-18, 27-23 the same!

Diagram (D) Forms the diagram. This is an interesting position and run up.

(E) This seems to lose. PP is 23-18, 11-16, 18-2, 16-30, 22-18, 30-26, 18-15 (G), 10-19, 24-15, 26-22, 28-24, 12-16, 24-20, 16-19, 20-16 ( the play ends here to draw by Peter Thirkell, but I continue ), 19-23, 16-12, 23-27, 12-8 ( surely what the author had in mind ), 3-12, 2-7, 27-31, 7-10 etc draws.

(F) 19-16 could be tried, but the piece on 14 would soon fall by bringing the king around to 17. After 19-16, 23-26, 16-12, even 26-22 wins by 11-8, 22-15, 14-10, 9-14, 10-1, 14-18 etc as the move is right.

(G off E) There seems to be several ways to finish this position to a draw. Another way is 2-7, 26-23 ( This was Marion's idea whereas 10-15 is ok too. I finish this with the following ), 7-14, 3-7, 24-20 ( or 18-15 now ), 23-26, 18-15, 9-18, 15-10, 6-15, 13-9, 5-14, 17-3 etc draws. I hope the readers enjoy this. If you find errors or have comments, please send to me so I may amend this. Don Lafferty, Oct. 16, 1997.

THE PIONEER
11-16, 24-19, 8-11, 22-18, 4-8, 25-22, 16-20, 22-17, 11-16, 17-13, 9-14, 18-9, 5-14, 29-25, 8-11, 25-22, 11-15, 30-25, 15-24, 28-19, 10-15(A1), 19-10, 6-15(AA), 22-17(A2), 16-19(C,E), 17-10, 7-14, 23-16, 12-19, 27-23, 19-24, 23-19, 2-6(A), 19-10, 6-15, 25-22, 3-8, 26-23, 24-27, 31-24, 20-27, 23-19, 15-24, 32-23, 24-27, 22-17, 8-11, 17-10, 11-15, 13-9 etc draws.

diagram (AA) Forms the diagram on the right, with White to move.

(A1) There is little doubt the usual pp 14-17 is safest, but a well known draw. This is a good vary with some winning chances. There seems to be many ways to continue and given in this paper are a few. If 14-17, perhaps a new line is: (Don "omo" Lafferty - Albert "atuck" Tucker - zone game Tuesday, November 3, 1997) 14-17, 21-14, 10-17, 13-9, 6-13, 25-21, 2-6, 21-14, 1-5, 19-15(X), 7-10, 14-7, 3-19, 32-28, 6-9, 27-24, 20-27, 31-15, 9-14, 15-10, 14-17, 10-7, 17-21, 7-2, 21-25, 2-7, 25-30, 7-10, 30-25, 22-18, 13-17, 28-24, 25-22, 10-14, 22-31, 14-21, 31-26, 24-19, 26-22, 18-15, 5-9, 15-10, 9-14, 10-7, 22-18 Red Wins.

(X) As far as I know this is new and most likely a loss. The pp I know is 22-17*, x, 7-11, 17-13, 6-10, x, 27-24*, x, and I like to finish it with 16-20, 23-18, x, 10-14, x, 13-9, 11-16 etc draw. Atuck knew this play, but he is to be admired for his romantic style of play just to find out what is in a new move and for the excitement of cross board play.

(A2) Wayne's fine reply and probably as good as there is. 13-9, 16-19, 23-16, 12-19, 22-17(A3), 1-5, 17-10, 5-14, 25-22, 14-18, 22-17, 7-14, 17-10, 19-23, 26-19, 15-24, 32-28, 18-23, 27-18, 2-7, 28-19 draws.

(A3) Arthur Reisman, in his fine Championship Checkers, The Pioneer System, on page 49, note A, offers as the best move: 9-5, 7-10(A5), 22-17, 3-8, 25-22, 8-12, 17-13, 14-18, 22-17, 19-23, 26-19, 15-24, 17-14, 10-17, 21-14, 18-22, 14-10, 24-28 (an excellent move by WCC, if 12-16, 32-28, 16-19, 13-9 may draw), 27-23, 22-25, 23-19, 25-30, 19-15(A4), 2-6, 32-27, 30-25, 27-23, 25-22, 23-18, 28-32, 18-14, 22-18, 14-9, 18-11, 9-2, 20-24, 10-7, 32-27, 31-26, 24-28, 7-3, 27-24, 3-7, 24-20, 7-16, 20-11, 26-22, 28-32, 22-18, 32-27, 18-14, 12-16, 14-10, 16-19, 10-7, 19-23, 7-3, 27-24 etc Red wins.

(A4) 31-27, 30-26, 19-16, 12-19, 27-24, 20-27, 32-16, 26-22, 16-11, 28-32, 10-7, 32-27, 7-3, 22-18, 11-8, 27-23, 8-4, 23-19, 3-8, 19-15, 8-3, 15-10, 3-8, 18-15, 8-12, 15-11 Red Wins. Notes A3 and A4 are good examples of how strong WCC is in the endings.

(A5) But, Reisman only gives 9-5 suggesting a white win and overlooks this fine reply which may win for Red!

(A) 15-18, 26-22, 18-23, 22-18, 24-27, 18-9, 1-5, 31-24, 5-14, 25-22, 20-27, 22-18, 2-7, 18-9, 7-11, 9-6(B), 27-31, 6-2, 31-27, 32-28, 23-26, 2-6, 26-31 draws.

(B) 32-28, 27-31, 28-24, 3-8, 9-6, 8-12, 6-2, 31-27, 24-20, 27-24, 19-16, 12-19, 2-7 etc draw.

(C) 2-6, 17-10, 7-14, 13-9(D), 6-13, 25-22, 15-19, 22-17, 13-22, 26-10, 19-26, 31-22, 16-19, 22-17, 12-16, 17-13, 19-24, 27-23, 24-27, 23-18, 27-31, 21-17, 31-26, 18-14, 26-22 draws.

(D) 25-22, 15-18, 22-15, 6-9, 13-6, 1-19, 27-24 (or 26-22 to also draw by Reisman), 19-28, 31-27, 3-7, 26-22, 16-19 draws.

(E) 7-10, 13-9, 15-18, 17-13, 10-15, 21-17(E1), 14-30, 23-14, 30-23, 27-11, 1-5, 11-8, 16-19, 8-4, 12-16, 31-27, 19-24, 27-23, 24-27, 23-18, 27-31 pretty draw.

(E1) 26-22, 16-19, 23-16, 12-19, 22-17, 2-7, 17-10, 7-14, 9-6(E2), 1-10, 13-9, 3-7, 9-6, 14-17, 21-14, 10-17, 25-21, 17-22, 6-2, 7-11, 2-7 (or 31-26), 19-24, 7-16, 22-26, 31-22, 24-31 draws DL vs Michael Holmes.

(E2) 9-5, 3-8, 27-24, 19-28, 22-17, 18-23, 17-10, 15-19, 13-9, 19-24, 21-17, 24-27, 31-24, 20-27, 17-13 etc draws.

11-16, 22-18, 8-11, 18-14(A), 9-18, 23-14, 10-17, 21-14, 4-8, 24-19(B), 16-23, 27-18, 12-16, 28-24, 8-12, 26-23, 16-20, 32-27(C), 7-10(D,G), 14-7, 3-10, 24-19(E), 10-14, 18-9, 5-14, 25-22, 6-10, 22-18, 1-5, 18-9, 5-14, 30-26, 11-15, 19-16, 12-19, 23-16, 15-19, 26-23, 19-26, 31-22, 10-15, 29-25, 15-19, 16-11, 2-6, 11-7, 6-9, 7-3, 19-23 etc draws.

(A) This fine move is called the Paisley Bust which is an effort to control the center, almost always a good idea.

(B) Continuing with the plan of controlling the center.

DIAGRAM (C) Forms the diagram and is a very good move played on me in a practice game by the "iron man with iron lines", the great Asa Long. The usually continuation is 31-27 and is well covered in the wonderful gold mine of play, Basic Checkers, part 6, page 19, trunk by the greatest annotator of all times, Richard Fortman.

(D) There is little doubt this is Red's best reply to 31-27 and is Red's effort to fight for the center. 7-10 is also OK against 32-27. Other ways are given below. There is a good history on this move against 31-27 in the above reference. Marion Tinsley brought my attention to this is a practice game many years ago.

(E) The key to avoiding trouble. If 25-21, 10-14, 18-9, 5-14, 29-25(F), 6-10, 25-22, 2-7, 23-19, 11-16, 27-23, 20-27, 31-24, 16-20, 22-18, 20-27, 18-9, 27-31, 9-6, 31-27, 6-2, 27-18, 2-11 then 18-22 looks like bad trouble for white.

(F) Or 24-19, 6-10, 30-26, 11-16, 26-22, 2-7, 27-24, 20-27, 31-24 etc leads to a similar sorry looking ending for White.

(G) 6-10(H), 25-21, 10-17, 21-14, 2-6, 29-25, 6-10, 25-21, 10-17, 21-14, 1-6, 24-19, 6-10, 31-26, 10-17, 19-16, 12-19, 23-16, 5-9, 18-15, 11-18, 26-22 etc draw.

(H) 6-9(I), 24-19, 7-10, 14-7, 3-10, 25-22, 9-14, 18-9, 5-14, 22-18 same as the trunk.

(I) 11-16, 24-19, 6-10, 25-21, 10-17, 21-14, 2-6, 29-25, 6-10, 25-21, 10-17, 21-14, 1-6, 27-24, 20-27, 31-24, 16-20, 19-15, 20-27, 14-10, 7-14, 18-2 etc draws.

The fine computer checker program, WCC, by Gil Dodgen did most of the heavy thinking in this analysis. Your comments, corrections and improvements will be greatly appreciated. Don Lafferty, Saturday, November 22, 1997



The following Opening was designated "The Glasgow Fife", by Conrad Cantor in his articles in "California Checker Chatter" (known as CCC). Cantor dubbed his articles-"Glasgow Gleanings." This 14-18? line at the 9th move is now suspect and the regular "Glasgow" with 11-16* is apparently forced at that point. In another game at the Vog site, I lost 14-18 to Don, following Cantors play-which Don corrected, and then won the ending. AL Lyman.

"THE GLASGOW FIFE"
11-15, 23-19, 9-14, 22-17, 8-11, 25-22, 5-9, 17-13, 14-18, 29-25, 11-16, 24-20, 16-23, 26-19, 15-24, 28-19, 10-15(A1), 19-10, 6-15, 13-6, 2-9(A2), 27-24(X), 4-8, 21-17, 9-14, 17-10, 7-14, 24-19, 15-24, 22-15, 24-28, 25-22, 1-6, 31-26, 3-7(A3), 26-23, 7-11, 22-18, 14-17, 23-19, 17-22, 20-16 (A scintillating sacrifice!), 11-20, 18-14, 6-9, 14-5, 20-24, 15-11, 8-15, 19-10, 12-16, 5-1, 16-19, 1-6, 19-23, 6-9 White can win.

At note X, I have only shown a few lines and realize there are many ways not covered. I would greatly appreciate your comments, corrections and ideas on this puzzling line. Don Lafferty, Tuesday, March 3, 1998. All play by WCC and myself. (Don Lafferty)

(A1) I recalled Al Lyman et al (your webmaster) studied this line and concluded 4-8, 22-15, 7-11, 21-17, 11-18, 17-14 etc was probably a white win. I was wondering what I would do if he moved 10-15. Lo and behold Murphy's Law prevailed again and he did it!!

diagram (A2) Forms the diagram on right.

(A3) 14-18, 22-17, 18-22, 26-23, 3-7, 23-18, 7-10, 15-11 White should win.

(X) This is an interesting position where White has choice of attacks and Red has several defenses to try. Another attack is 30-26, 4-8, 26-23, 1-5(B), 23-14, 9-18, 21-17, 5-9, 17-13, 9-14, 13-9, 7-11, 9-6, 14-17, 22-13, 18-23 etc with White obviously strong.

(B) 9-14, 32-28(C), 1-6, 28-24, 7-10(D), 22-17, 8-11, 31-26, 12-16, 26-22, 3-8, 17-13, 15-19, 24-15, 10-26, 22-15, 11-18, 20-4, 26-31 etc, White should win.

(C) Recently in vog, TJ121 (unknown to me who this is) and I reached this position from a slightly different order of moves. I had White and missed the point here and played 23-19, 15-24, 22-15, 7-11, 32-28, 11-18, 28-19, 1-6, 31-26, 3-7, 26-22, 7-11, 22-15, 11-18, 19-15, 6-9, 27-24, 9-13, 24-19 etc drew. This was nice playing by my opponent.

(D) 6-9, 23-19, 7-10, 20-16, 3-7, 24-20, 15-24, 22-6, 12-19, 6-2, 7-11, 2-7, 11-15, 20-16, 24-28, 16-12, 28-32, 12-3, 32-23, 25-22, 19-24 etc WW.
