Wednesday Workout: More World Youth Mates

Last week we challenged CLO readers to solve some mates in ones and twos from the 2019 World Youth Championships. This week we ratchet up the difficulty. Can you solve these mates in threes? A mate in five? How about a mate in seven? Without further ado... Mates in three Mate in five Mate in seven!
