Mr. Al Darrow, the checker player and checker historian with a encyclopedic knowledge of the game (and a terrific library), sent me these lovely games between multi-gamer/author Irving Chernev and the legendary Willie Ryan and the equally legendary Sam Gonotsky . The notes/annotations are by Irving Chernev and Mr. Darrow himself; those annotations marked "(ad)" at the end of the note are Mr. Darrow's. I am posting these games with Mr. Darrow's permission to do so:
Black "Irving Chernev"
White "Willie Ryan"
Result "Draw. Chernev missed a win."
10-14 24-20 11-15 28-24 6-10 22-17 9-13 23-19
13-22 25-9 5-14 26-22 ((A) Ginsberg says this loses, although Banks' book shows
a beautiful draw. ["Banks' Scientific Checkers", 1st and 2nd eds., p. 86, var. 2]))
8-11 22-17 15-18 29-25
1-5 ((B) 11-16, 20-11, 7-23, 25-22 looks like a draw.))
31-26 11-15 17-13 4-8 (Ginsberg says 5-9 wins.)
26-23 8-11 30-26
11-16 (If 5-9, 13-6, 2-9, 19-16, 12-28, 20-16, 11-20, 21-17, 14-30, 23-5, 30-23, 27-2, drawn.)
20-11 7-16 26-22 (If 13-9, 14-17, 21-7, 3-10, 23-7, 16-30, 25-21, 5-14, Black best.)
2-6 21-17 14-30 23-7
3-10 22-17 16-23 27-11 30-25 11-7 10-15 7-3
25-21 17-14 15-18 3-7 6-10 14-9 5-14 13-9
10-15 9-6 18-23 7-11 14-18 6-2 21-17 2-6
17-14 11-7 12-16 6-10 16-19 10-17 19-28 7-11
((F) Star move to win and forms a beautiful problem. In the actual game Chernev played 7-10,
23-26, 10-19, 26-30, drawn.))
15-19 ((G) If 23-26, 17-14 W. wins.))
11-16 19-24 17-14 18-22 ((H) If 24-27 16-19, W. wins. If 23-27, 14-23, 27-31, 16-19, 31-27, 23-18, 27-31, 18-22. W. wins.))
14-18 24-27 18-25
((J) A relative of No. 2 in The J. Ash--R. Home Bridge Family, p.109, "Boland's Masterpieces".(ad))
27-31 25-30 31-27 16-20 27-31 20-24 ((K) Intersects the R. Home position near the end,
where the solution gives 19-24. (ad))
31-26 32-27 23-32 30-23 ((I) American Checker Monthly, Vol. IV, p. 308, Game 204.
((Dec., 1924) This was the seventh game of a current Brooklyn Checker Club match between
Chernev and a seventeen year-old Ryan.(ad) The solution at this point is the famous J. Sturges Double Corner Block with a extra King on 24.))
Black "Irving Chernev"
White "Sam Gonotsky"
Result "Gonotsky won"
9-14 24-20 5-9 22-18 10-15 ((A) Most leading players prefer 11-16 here, but this is just as good.))
28-24 ((B) Better than 27-24. 25-22 allows Black a powerful game by 7-10 or 15-19.))
15-22 26-10 7-14 25-22 1-5 22-17 14-18 23-14 9-18 30-26
3-7 26-22 ((C) Probably safest although 32-28 will draw. If 17-14, Black replies 6-9 and has the better game.))
18-25 29-22 ((M) During the opening and early midgame development, no distinctive formation pattern arises.
The situation might be described as extremely open. From this point horizontal distribution of forces predominates.
Much like two enemy forces opposing each other across a "No Man's Land" -- a kind of trench warfare approach.
I call this midgame development Entrenchment. Sooner or later the forces must breakthrough for kings or run out of moves. (ad))
6-10 ((D) If the piece on 32 were on 28 the setting would be the same as a position brought up from a popular line
of the 9-13, 24-19 opening, colors reversed, thus: 9-13, 24-19, 11-15, 28-24, 6-9, 23-18, 1-6, 18-11, 7-22, 26-19, 8-11,
25-22, 11-16, 19-15, 10-19, 24-15, 3-7, 30-26, 7-11, 15-8, 4-11.))
27-23 10-15 23-18 12-16 ((E) Black gets a weak game after this. 11-16, 20-11, 7-16, 18-11, 8-15, 24-20, 16-19, 17-14, 19-23,
22-17, 15-18, 14-10, etc., drawn.))
31-26 5-9 17-14 9-13 ((F) 16-19, 14-5, 19-28, 5-1, 15-19 leads to a long ending, but White seems to have a winning advantage.))
14-9 7-10 26-23 ((G) Of course if 9-5 or 21-17, 10-14 draws.))
10-14 32-28 ((H) 9-5 is interesting.))
13-17 ((I) 16-19 doesn't work now: 16-19, 23-7, 2-11, 24-19, 15-24, 28-19, 14-23, 2-6, 23-26, 6-2, 26-30, 2-7, 30-25
[8-12 no better], 7-16, 25-18, 16-12, 8-11, 12-16, White wins.))
22-13 15-22 9-6 2-9 13-6 ((M) Both sides have broken through. Often a sacrifice is required [e. g., Cowen's Coup. See "Boland's Checkers in Depth" for many examples]. Often a draw is achieved, here the prognosis is a White win. (ad))
22-26 6-2 26-31 2-7 ((J) 2-6, 31-27, 24-19, 27-18, 19-3, 14-17, 21-17, 18-2, 28-24, 11-15, drawn.))
8-12 7-3 4-8 3-7 31-27 7-10 27-18 10-17 18-23 ((K) 18-15, 17-14, 16-19, 21-17, 19-23, 24-19, 15-24, 28-19, White wins.))
17-14 16-19 24-15 11-18 28-24 8-11 24-19 23-16 14-23
((L) A neat finish. Gonotsky. American Checker Monthly, Vol. IV, p.307, game 202 (December, 1924.)
This Right Hand hold, Oldbury calls Parameter 15F (Parm 15 since Man + King holds 2 Men + King and F because the holding man on 20 occupies Diagonal F (Oldbury's Diagonals were defined in his "Move Over".) See a fuller discussion of this parameter in Oldbury's "Complete Encyclopedia of Checkers", p. 509-11. Probably the clearest discussion of this concept is found in Pask's "Key Endings", p. 81-2. I like the concept, but I can understand why it isn't everyone's cup of tea. (ad))
Thanks, Mr. Darrow. It is always a pleasure.
V/R,
