Contest #18 - Kingless Triple Jumpers - July 26 - August 31, 2014

As requested, Contest #18 targeted problems that can arise in games. But this is not what composers normally do. Only three such problems were entered. So two compositions that looked like they might occur in games were added as fill-ins. The result turned out to be a contest of kingless triple jumpers with a secondary battle of composed settings versus game settings. Both competitions ended in ties.
___________________________________________________________________________

The winning "composition" with 7 votes, was the final fill-in, Breakthrough, by Ed Atkinson. It was a masterfully pleasing 3-for-1 into 2-for-1 compound stroke, triggered by two unnatural pitches, and followed by straightforward 2x2 afterplay.

The contest had been set to go with only four problems. Unfortunately for its competitors, Breakthrough broke in literally at the last minute to take a share of the championship from Jim Loy, winner of the last contest. Of passing note: Breakthrough was the least natural setting. It casnnot occur in a game.
___________________________________________________________________________

The winning "game problem", also with 7 votes was Practically Practical, by Jim Loy, retaining a piece of his title. The setting corrected Tescheleit's Master Play, but raised serious issues.

First, its inclusion in the contest was questioned because the winning tandem 2-for-1 and 3-for-1 shots were allegedly too easy.

Later there were questions as to whether the tandem shots really produced a forced win. Without a forced win, the problem would be disqualified.

Jim Loy and Liam Stephens both re-examined the afterplay, but did not reach any unequivocal conclusions. The problem that started out too easy became the most difficult of all. Finally, Sune Thrane saved the problem by demonstrating a 124-move win using his MFC Program.

If you hope to make "practical" use of all this, check out the expanded solution, including a full alphabet of notes. Sorry, it is not animated yet.

Salot's question: Would you ever play for this win when you have to knowingly play a losing move to get to it? Atkinson's answer: It depends on who the opponent is.

Here is the Practically Practical run-up:
9-14, 22 18, 5-9, 21 17, 14-21, 18 15, 11-18, 23 5, 8-11, 25 22, 4-8, 22 17 {This and 29 25 both lose; 27 23 draws, Sune Thrane}, 12-16, 24 20, 16-19, 29 25, 11-15 {This forms Practically Practical}; see the solution for the continuation.
___________________________________________________________________________

In third place with 5 votes was the other composed fill-in problem, The Dreamer, by Roy Little. It had the fewest pieces, and was the only deferred stroke. It employed two unnatural pitches into an in-and-out theme, without the out part, leading to a 3-for-1, followed by a clear-cut, 2x2 finish. Of passing note: it is not possible for The Dreamer setting to occur in a game.
___________________________________________________________________________

Trailing were strokes from unpublished computer games.

Bridge Too Far, with 2 votes, mercilessly victimized its author, Bill Salot, during a game in which Kings' Row removed 8 pieces, including a climactic 3-for-1, and concluding with a winning bridge thwarting Bill's subsequent escape efforts.

Here is the Bridge Too Far run-up:
9-13, 22 17, 13-22, 25 18, 10-15, 18 14, 15-19, 24 15, 11-18, 28 24, 6-9, 29 25, 8-11, 24 19, 9-13, 19 15, 4-8, 23 19, 11 -16, 26 23, 13-17, 30 26, 7-11, 15 10 forms Bridge Too Far, colors reversed
___________________________________________________________________________

It can now be divulged that the S-------- Swindle was really the Schwartz Swindle, discovered on his computer by first time contestant, Joe Schwartz. Joe showed it to some friends, including Brian Hinkle, who entered it for him with his permission. All had high hopes for it based on its multiple traps featuring four different triple jumps, requiring both sides to play perfectly to survive, and suggesting practical possibilities. Alas, contest policy did not allow Joe's friends to vote. His problem came in last with only one vote.

Here is the Schwartz Swindle run-up:
9-14, 22 18, 10-15, 18 9, 5-14, 25 22, 15-19, 24 15, 11-25, 29 22, 6-10, 22 18, 14-17, 21 14, 10-17, 28 24, 8-11, 24 20, 3-8, 1814, 1-6, 27 24, 11-15, 32 28, 15-18, 31 27, 18-22 forms the Schwartz Swindle
___________________________________________________________________________

Overall, the 2 compositions combined outpolled the 3 game problems combined, 12 to 10. The collective mindset of the judges remains difficult to discern. But this contest did nothing to discourage composers from creating problems unrelated to actual games.

During Contest #18, 356 visited the site, breaking the old contest record of 315. The 22 vote total has not been exceeded since Contest #4 in May 2012. Those are good signs.

Here is how Contest #18 was introduced on July 26, 2014:

Some of our past voters have expressed a preference for natural-looking problems. Behold these five practical teasers by competing authors. There are no kings, no numerical advantages, and their solutions will show they have something else in common. To our knowledge, all are previously unpublished. No clues are needed for above average players to solve them.

At least three of the five settings can arise in a game. One is a correction of published play.

We have very few kingless entries like these. Contests featuring them will not recur very often. The voting in this contest may be a measure of their popularity.

See them animated & vote for your favorite. Game run-ups and authors' names will be published after the polls close on August 31st.

ACorrects Tescheleit's Master Play, Part 2, DC-3, P 127, V 29, where Tescheleit plays 27 24, 15-18, which is a RW. "A great example of a practical dilemma that comes up in a lot of games, should I go for the shot or not?" LoyRed Wins
B"Is it possible that Red can draw after the stroke? White has lots of work ahead", Ed AtkinsonWhite Wins
C"Jim, Ed asked this about your contest problem. What is your response?" Bill Salot White Wins
D"My reasoning was that the White king can get out of the single corner. It still looks that way to me, but there are other possibilities, like maybe one king v. one king is not good enough, even with an extra piece. So, I must study it", Jim LoyWhite Wins
E"Liam, Jim Loy is evidently having trouble resolving this. Can you help?" SalotWhite Wins
F"When I originally looked at Practically Practical I did play out a number of endings for some moves and my recollection is that they ended in White Wins. It is however a difficult end game for White", Liam StephensWhite Wins
G"I tried out the ending on my other program (Wyllie) which has the 8 piece database, but set on Automatic it came up with draws. I'll ask Sune if he can have a look at the position if he has time to do so", StephensWhite Wins
H"It is a one of those ‘Interesting’ positions that the computer can have difficulties with; most programs seeing the win, but having trouble actually executing it", Sune ThraneWhite Wins
I"Most computers prefer 10-15 to 6-9 at this second move after the shot, but it doesn't make a difference", ThraneWhite Wins
JLeaving the piece on 10 temporarily impedes the White king, SalotWhite Wins
K"If Red goes for two kings, it looks like White gets two kings, too" LoyWhite Wins
L"I can confirm that it is a white win. I have only verified your (Stephens) first 12 moves since it took me quite a while. The first moves - which are the same as yours - are definitely correct", ThraneWhite Wins
MThis is the first threat of an exchange; White’s objective is to force exchanges while maintaining its numerical advantage; the stars from here on out are by Mr. Thrane, Salot White Wins
N"I tried 19 15 here (to prevent 22-18) but it only draws", Stephens; "19 15, 26-30, 4 8, 30-26, 8 11, 26-23, 11 16, 23-18, 15 19, 2-7, Draws", Thrane.White Wins
O"If Red goes for a third king, I don't think White can stop it. But then White can probably get a third and fourth king", LoyWhite Wins
PNot 6-9, 11 7, WW faster, SalotWhite Wins
QKey maneuver coming up, SalotWhite Wins
RThis king is the one that eventually prevents Red from getting a third king, Salot White Wins
S(4 places) - Threatening an exchange, SalotWhite Wins
T"Kingsrow picks 11-8 here, which only draws; 27-31 is the only move to win", ThraneWhite Wins
U"Still Kingsrow wants 11-8, but 23-26 is only move to win", Thrane White Wins
V"Finally now that we have the piece locked on 21, we can go in", Thrane White Wins
WNot 11 15, 13-17, Draws; White must clear the way for a fourth king. SalotWhite Wins
XThreatening 16 11, 7-16, 24 20, Salot White Wins
Y"Not 9-14, 15 10, 14-9, 22 17, WW faster; at this late point in the analysis, the fun is pretty much over, and I didn’t spend much time on refining the play; most White moves win with little effort", ThraneWhite Wins
Z"If 2-6, 11 15, followed by the trade, WW", ThraneWhite Wins
