It's actually quite funny that the four Danes drew eachother. It could be some interesting clashes. Mai Grage and Maria Jespersen are ranked no. 3 and 4 in Denmark (after Woz and Barbat) and bump into each other a lot in tournaments in Denmark (Championships etc.). Mai Grage was 6-0 H2H in 2012, but the matches were often quite close, for instance 76(4) 67(4) 63 at the Danish Championship SF. But Mai should be the favourite.
Martine Ditlev (age 16) and Karina Jacobsgaard (33) are almost a generation apart. Karina has also been Martine's coach on the National junior Team! Martine ought to win this, but maybe Karina's experience and knowledge of Martine will help her.
