Yes... Thank you, Vadim.
For other contestants, new and old, that didn't know this, the name of the strategy and the name of the file are "case sensitive", which means there is a difference between upper and lower case letters.
That difference can mean "Compilation Error" and really forfeit your chance to participate in the strategy contest for one month.
Just wanted to clarify this for other people who got in the same situation as I did.
Good luck this month to everybody, and watch out next month
I'm coming back !
Cheers.
