I think Caissa should create a new section with all the unfinished games after a minimum of moves. It is not correct to say they have 400 results if 75 of them start with 1 e4 and that's it.
Also they shouldn't give any ratings points to the winner. They used to do like that in the old site.

I think the minimum number of moves should be at least 10 unless one of the players got mated before move 10.

We are aware of the unfinished games problem in the Corr area. We will fix this in a future update.
