Feature: Ghost Chess

This actually seems really interesting! Strength of each player and how they play against an opening can be analyzed and moves can be made accordingly. Its quite similar to the 'Play Magnus' app.

Sounds cool!

I like it, but there is a problem. When would you see the ghost? After the move? That leads to another. What if, after seeing your ghost, you takeback and then make the ghost move?

You play *against* your ghost and try to beat yourself.

sounds fun, but it would require a rather sophisticated program that can analyze your play style and strength and create an accurate reflection of yourself, that includes the openings you use.
