Why can I only move my Queen vertically? I'm playing a game on chess.com and I want to move my Queen to h7. The website won't let me move it there. I tried moving it to other places but the only way I will let me move it is vertically. Is there a rule or something I'm missing, or is this a bug in the game?
The Rook on e8 is pinning your Queen against the King. You cannot expose your King to check.
