Claudio's audio is the beginning of a lesson he held to his students, After the holidays.

This is the translation:

"Hello to all chess players,
I'll be yours on Thursday too. Just to give you some chess hammered.
But in the meantime I'm launching a challenge, To see how much you've been ruffling during the summer.
Try to solve this challenge:

Position of White:

pawn e5,
King f5.

Position of Black:
King f7.

White moves and wins,
Or the black moves and is draw.

Follows the satanic laughter... "
