Board for lectures, with arrows, highlights, not checking rules Is there good free software for creating video lessons, that allows you to make board as big as desired, highlight squares, show arrows and not checking rules, allowing to move pieces in any way, playing without king etc? I mean just board software, not software for capturing video.
You can use a setup board function is programs like scid and chessbase.  These boards aren't full screen. In setup mode, they don't allow for arrows and highlights.
It might be better to just program the software yourself.  This would make all the features just as you like.

Chessity.com has a new e-tool for teachers.

Allows illegal moves, coins and flags on any square, and four colored arrows and squares.  Large enough for students in back to see clearly.
