Delmotte Thierry played 41. 39-33 ?
Best move is 38-33 with 08-13 [où?] 33-28x28! : white have a good play.
For example : 13-19 32-27 19-24 43-39 24-29 39-33 27-22x43 12-18 43-38 18-22 28-23 22-27 23-18 17-22 26-21 22x13 21x32 13-19 39-33 08-13 32-28 13 ...

Maxime Kouamé played at the 52th move : 30-25 and, after 17-21 53. 27-22 he haved a lose end-game.
In the diagram-position, the best move is 52. 41-37 because if black play 17-21 there is 53. 38-33! with remise.

The combination, after 42. 38-32 18-23 43 ...

39. ..-.. 12-17
39. ..-.. 23-28 is very bad because there is the gambit 40. 22-17! and 41. 38-32! +.

45. 42-38 17-22 46. 47 ...

39. ..-.. 12-17
If Black play 39. ..-.. 11-17 40. 22x11 16x07 White have a good play with 41. 37-32! 21-27* 42. 32x21 26x17 43. 48-42! et now for example :

Excuse-me, the first diagram in my text is wrong.
I corrige the position.
The position after the 28th 42-37 is :

Position after the 28th move 42-37 :

28. ..-.. (09-14)
The best alternative is (21-26) 47-41 (09-14) 41-36 (24-29)! 33x24 (19x30) 35x24 (20x29) 34x23 (18x29) but the white's game is more facility.
The others moves is losing :
*1. (03-08) 28-23! (19x28 ...

Position after the 50th 32-28.
http://fmjd.org/dias2/save/11143453142.png
50. ..-.. 17-22 ??
Decisive error.
Perhaps De Meulenaere haven't got much time in the clock.
50. ..-.. 17-21 is the best move and black have remise after 51. 27-22 18x27 31x22 06-11!.
After 50. ..-.. 17-22, De Meulenaere ...

Ron Heusdens has played a good game against De Meulenaere in the firt round.

38. 45-40 ! 35x44 39. 39x50

Excuse-me, my English is not perfect.
I would to say : breakthough to king or opening to king.

42. ..-.. 18-23 ??
The decisive error.
It was necessary to defend itself by 42. ..-.. 21-26 [threaten 16-21] suivit of 43. 32-28 and 08-12 and the game can continue.
It's less good to reply 43. 22-17 [at the move ...

I draw your attention to the Kirzner/Lognon's end of game.
Position after the 65th move (37-41) : http://fmjd.org/dias2/save/11142666444.png
Kirzner played at the 66th move 24-19?? whereas it seems to me that the white had the remise "in the hands" by 66. 33-28! and now two variants :
1. 66 ...
