Some really nice logic in the beginning with tough anti-knight toward the end. Very fun to solve.
(Reply) Thanks. The anti knight at the end became slightly more difficult than intended, but I also liked a lot of it, so left it as it was. Thanks again for playing and nice comment :-) Godrick

Great puzzle ! The interactions between the little killer clues and the anti-knight constraint are rich and powerful. Thanks a lot !
