Selected Positions in Lille, Rd1 (Men)

Postby Alex_Moiseyev on Fri Aug 31, 2012 9:21 pm

I am starting here now a new series of "Selected Positions in Lille" which include all most interesting things I find. This work do not pretend to be a final word or any serious, deep analyses of games with professional comments and references. This important work is still ahead and I hope other experts join me.

I will create a separate topics for each round.

==============================================================================
Red to move.

J. Morrison vs R. Beckwith, G1.

Quite impressive - not looking very natural 1-6 is OK but 3-7 as Jim played, is already complete loss ... amazing !

Red to move
Image
O. Kolin vs R. King, G1

It was shown in Sixth that 7-10 here is probably the only move giving red an even game. Oleksandr played 11-16? here and eventually lost.

I. Martinov vs V. Shafir, G1

Igor played here 32-27? to unfortunate draw. Very costly mistake. 20-24 instead should win the game after 19-15, 32-28, 15-10, 7-11, 10-6, 11-15, 18x11, 9x22, 30x21, 27-24 WW

C. Freeman vs U. Hydyrov, G1

11-16?? 3-7 Draw Knowing Chuck as a very ambitious man, I understand now better what happened with him in this tournament. This first game in first round was a very big psychological shock for him where he was unable fully recover to the rest of event ... just guessing.

S. Thrane vs G. Owens, G1

6-10?? No cigars ! Loses at earlier stage. This position is well known to PP where both 3-7 and 8-11 are sound and recommended. it was shown in Sixth that 12-16 at this point gets red into serious troubles though not loses yet.

White to move and win
Image
J. Jolliff vs D. Oliphant, G1

Red last move was 8-11? which suppose to lose. Mr. Oliphant played drawn 29-25 here but later won the game without much problems. I find it quite interesting and curious that Kingsrow opening book has here the followng long play generated by program. Is this the only winning way for white ?! Anyway, good thing to know how to beat losing 8-11? at earlier stage. Continue from diagram ,,,

... 24-20 6. 16-19 29-25 7. 3-8 25-22 8. 1-6 21-17 9. 9-13 17-14 10. 6-9 27-24 11. 11-15 18x11 12. 9x25 24x15 13. 7x16 20x11 14. 25-29 26-22 15. 5-9 32-27 16. 12-16 27-23 17. 9-14 22-18 18. 14-17 18-14 19. 17-21 14-9 20. 29-25 9-5 21. 25-22 5-1 22. 22-17 23-18 23. 17-22 1-5 24. 16-19 18-14 25. 19-23 14-10 26. 13-17 28-24 27. 22-18 30-26 28. 23x30 10-6 29. 2x9 5x23 30. 21-25 11-7 31. 25-29 7-3 32. 8-12 15-10 WW

White to move.

M. Bernini vs P. Faolo, G1

Red previous move here was 11-16 which is out of order, 4-8 was correct. White responded 30-26? and after 9-13 play returned back on PP. It seems like in position on diagram after 17-13 white has scientific win. Continue from diagram ... 17-13, 3-7, 31-26 and now red has two ways:

1) 10-15, 18x11, 14-17, 21x14, 9x18, 23x14, 16x23, 27x18, 20x27, 32x23, 7x16, 25-22, 16-20, 23-19, 20-24, 14-10, 6x15, 18x11, 24-27, 26-23, 27-32, 30-26 etc WW

2) 4-8, 25-22, 14-17, 21x14, 10x17, 29-25, 17-21, 22-17, 7-10, 18-14, 9x18, 23x7, 16x23, 27x18, 20x27, 32x23, 2x11, 23-19, 11-16, 25-22, 16x23, 26x19 WW

White to move.

G. Owens vs S. Thrane, G2

22-18 is correct giving white even game, but 22-17? (as played) loses.

Red to move
Image
J. Tichy vs F. Kareta, G2

From Doctor PP: 4-8 draw, 9-14 (as played) loses

White to move

U. Hydyrov vs C. Freeman, G2

25-22?? (31-26 Draw) 11-15 etc RW

Diagram 1. Red to move ............ Diagram2. White to move.
Image ... Image
V. Shafir vs I. Martinov, G2

Continue from diagram #1 ... 17-22? (9-13 or 4-8 Draw), 13x22, 9-13, 19-16, 13x22, 27-24, 20x27, 32x23, 11x20, 14-10, 6x15, 18x2, 22-25 2-6, 25-29, 6-10, 29-25, 21-17, 25-22, 17-13, 22-17, 23-19, 4-8, 19-15, 8-11, 15x8, 3x12 and we reached position on diagram #2. here Igor missed a win after 31-27? (31-26* is correct), but Vitaly didn't accept this gift and after 17-21, 10-14, 21-25, 13-9 played losing 25-30? instead 12-16* to draw.

White to move
Image
R. King vs O. Kolin, G2

Oleksandr didn't play accurately in the beginning of game, having a strong side of opening 10-15, 22-17, 9-13 but here he still had a chance to play beautiful 31-26* which saves the game. Instead, he played losing 30-26? and eventually ran out of moves.

Red to move
Image
D. Oliphant vs J. Jolliff, G2

This particular game was really a comedy of errors where logical scientific result of game changed several times. I strongly recommend you play this game on your own and enjoy all beauties and missings. I am giving here the last moment where result was changed.

Red played here 16-20?? (16-19 or 11-15 wins) and after 22-18* draw was soon agreed.

THE GEMINI 8-11 LOSS


J. Jolliff vs D. Oliphant, G1

Red last move was 8-11? which suppose to lose. Mr. Oliphant played drawn 29-25 here but later won the game without much problems. I find it quite interesting and curious that Kingsrow opening book has here the followng long play generated by program. Is this the only winning way for white ?! Anyway, good thing to know how to beat losing 8-11? at earlier stage. Continue from diagram ,,,


More on this losing 8-11 Gemini play can be found on the Forum under "Openings" posted in 2006 by Ed Gilbert and Mac Banks.Ed Gilbert said at the time ONLY 24-20 beats the 8-11 loss.[tc]


"After 8-11 then I would go 21-17 7-10 17-13 1-6 27-23 16-20 [[A] 24-19 9-14 18-9 5-14 29-25 4-8 26-22 11-15 25-21 15-24 28-19 3-7 22-18 14-17 21-14 10-17 18-14 8-11 14-9 now sure looks like a white win to me."Mac Banks........

[A]........I had a quick look at this ,Ed Gilbert didnt show any analysis on Macs 21-17 so i had a quick look and instead of 16-20 perhaps 3-7!! will draw the 21-17 attack.[tc]

8-11??.., 21-17,
7-10, 17-13, 1-6, 27-23, 3-7!!!, .........24-19, 9-14, 18-9, 5-14, 29-25, 14-18,
23-14, 16-23, 26-19, 10-17, 28-24, 4-8, 24-20, 6-10, 13-9, 17-21,
31-27, 11-15, 19-16, 12-19, 30-26, 21-30, 20-16, 30-23, 27-4, 19-23,
16-12drawn.[tc]

They are all interesting positions.
Which one makes the best problem?
Is that one better than any or all of the problems in the current problem composing contest?
How about picking one from a later round and entering it in a future contest, rather than exposing it here?

Should I appologise and/or remove my "Selected ..." posts ? :roll:

Bill, be accurate with terminollogy - there are no PROBLEMS in "Selected ... "posts, these are POSITIONS. Requirements to compositional problems are much more restrictive:

economic finals, economic solutions, no duals, no alternative soluition.

All these requirements hardly apply to practical postions from real events.
