Nope. Only displays the board on the console. An early version had the 
forward movement for pawns implemented.

My code has display and engine as separate classes with a main loop 
coordinating things between the two. The main loop requests the board 
state (dict) from the engine class and passes that to show board on the 
display class.

Very interesting. Something to add to my research notes. I'll muddle 
through with my code and let it grow organically for now.  If I decide 
to write a chess engine that implements the UCI protocol, I'll start 
over with a clean slate.

Thank you,
