Making illegal moves with chess_200.kif

[aindilis]

Thank you for making this awesome program. It's pretty complex, so I thought I would ask first before trying to debug it if you knew why it seems to be making illegal moves on the chess_200.kif domain? Fwiw, I am interested in using this domain and GGP-Botter to do Prolog-based positional analysis of chess games using predicates encoded from analysis texts.
