8.Dg5+ Ré8 9.Dé5


Each correct solution was awarded 10 points.

0,5 could be losed for writing + instead of # in solutions to 4 and 7

Some partial points for spotting part of the content (for example, 3 points
for those indicating try 1.Td1-h1 in 3 instead of 0 point for those
spotting nothing).

Results :

1. Pascal Wassong 99,5 (2h0')

2. Marken Foo 92 (2h10')

3. Thierry Le Gleuher 80 (2h30')

12 participants

Clear Champion is once again Pascal Wassong (spotting François (Labelle)'s
mate but losing half-point on Andrew's mate!)

Great sensation is stunning result at first participation by young Marken
Foo from Singapoor (completing his studies in France), missing only
solution (instead of try) in 3. and the 2 mates in 4 and 7.

Most difficult problem proved to be 5 by François (Perruchaud) solved only
by the 2 top solvers.
