Whilter Loss

[Lisle Cormier]

Over the weekend, I worked out a loss in the Whilter with a neatly wrapped endgame. Below is what I believe to be White's line of maximum resistence.

11-15, 23-19, 9-14, 22-17, 7-11, 26-22? (A), 11-16*, 17-13, 16-23, 27-9, 5-14, 32-27, 3-7? (B), 30-26, 7-11, 24-20? (C), 12-16*, 22-17, 16-19*, 27-23, 19-24*, 28-19, 15-24, 26-22, 24-28*, 22-18, 6-9*, 13-6, 2-9, 17-13, 1-6*, 23-19, 14-23, 19-16, 11-15*, 16-11, 28-32*, 11-7, 32-28*, 7-3, 8-11*, 25-22, 9-14*, 22-17, 28-24*, 20-16, 11-20, 3-7, 24-19*, 7-2, 15-18*, 2-9, 20-24*, 29-25, 23-27*, 9-5, 27-32, 5-9, 32-27*, 9-5, 4-8, 5-9, 8-11*, 9-6, 19-15*, 6-2, 27-23*, 13-9, 15-19*, 2-6, 11-16, 6-22, 19-15*. Black Wins.

A. Loses.

B. Allows a draw. Instead, I propose 12-16* to win as shown in my post below.

C. Albert Tucker's 24-19 improvement appears to draw.

Well, to me the other take seems more critical:
1. 11-15 23-19, 2. 9-14 22-17, 3. 7-11 26-22, 4.11-16 17-13, 5. 16x23 and now not 5.- ... 27x9, which is easily bad, but the more complicated 5. ... 27x11.
After 6.8x15 I would play 6.´... 30-26.
With ideas such as 7. 12-16 13-9!, 8.6x13 22-17, 9.13x22, 25x11, and though the man on 15 looks vulnerable, I want to know how to take advantage of it, for instance:
10. 3-8 ? 24-20 and white is much better,
or 10.16-20 24-19, 11.3-8 11-7!, 12. 2x11 19-16! and the white king will easily compensate the piece.
Maybe 10.14-18, but that does not look like a clear win to me with at least good practical chances for white.

Maybe you can give the line you worked out against that ?

I am giving here a diagram for easy visualization:




Lisle, I agree with losing status of line after 27x9.

Ingo, after 27x11, 8x15, 30-26 red should win after 14-18

To both: the draw maybe hidden somewhere after 27x11 8x15 32-27 etc.In this case 14-18 will be an easy draw after 24-19, and if red plays 12-16 then we can return back with different order of moves to Ingo lines: 13-9 6x13 22-17 etc.

The move 26-22 has actually been played before in a US national.
It was in a game played 1924, 3rd round, page 178 of the Tournamnet book by John J. Finley, comments given here by F.R: Wendemuth(my comments in brackets):

Lewis-Herskowitz, US nationals 1924, 3.rd (game3)
1. 9-14 23-19, 2.11-15, 22-17, 3.7-11(= Transposition) 26-22 (A), 4.11-16 27-23(a sideline we did not consider, but seems to be an outright loss), 5.16-20 31-27 (White already looks cramped), 6.8-11 17-13, 7.4-8 22-18, 8.15x22 25x9, 9.5x14 30-26, 10.11-15(B) 29-25, 11.8-11 19-16, 12.12x19 23x7, 13.2x11 26-23, 14.3-8 23-19, 15.8-12 25-22, 16.14-18 22-17, 17.18-23 27x18, 18.20x27 32x23, 19.15x24 28x19, 20.10-15

notes:

A) Something new, but it does not look strong.
B) Lewis misses the win here as follows: 10.11-16 26-22(C), 11.8-11 22-18, 12.1-5 18x9, 13.5x14 29-25, 14.3-7, Black wins.
C) 10. ... 19-15, 11.10x19 24x15, 12.6-9 13x6, 13.1x19 29-25, 14.14-18 23x14, 15.19-24 28x19, 16.16x30, Black wins.

re-whilter loss? Is it really a dead loss,or just on life-support.11-15,23-19,9-14,22-17,7-11,26-22,[A].11-16,17-13,16-23,

[A] said to lose,but does it?
[B]Mr. Cormier played 24-20 here and showed a loss.We going to utilize our trading power with 24-19 here and hope.
[C] I,m sure someone may find a win after the 26-22 at [A] but it would be interesting.Good Hunting,Albert Tucker

[Lisle Cormier]

Nice find, Albert! Since the 24-19 exchange knocks out my previously posted 27-9 line, an earlier 12-16 may patch the hole.

11-15, 23-19, 9-14, 22-17, 7-11, 26-22?, 11-16, 17-13, 16-23, 27-9, 5-14, 32-27, 12-16* (A), 13-9, 6-13, 22-17, 13-22, 25-9, 8-11*, 21-17, 4-8*, 17-13, 10-14*, 29-25, 15-18, 9-5, 11-15, 24-20, 8-11, 31-26, 16-19, 26-23, 19-26, 30-23, 3-8, 25-21, 8-12, 28-24, 12-16*. Black Wins.

A. Instead of 3-7? in the initial post.

[Lisle Cormier]

Since Ingo posted a tournament game in which 27-23 was used, here is a follow-up.

11-15, 23-19, 9-14, 22-17, 7-11, 26-22?, 11-16*, 27-23 (A), 8-11, 17-13, 16-20*, 22-18, 15-22, 25-9, 5-14, 29-25, 20-27, 31-24, 4-8, 25-22, 11-15, 24-20, 15-24, 28-19, 8-11, 32-28, 11-15, 30-25, 15-24, 28-19, 3-7. Black Wins.

A. In lieu of 17-13 as shown above.
