Still implementing full Algebraic Chess Notation.

A very well thought out design, clean approach. One thing I'd like to suggest, I see a lot of If else statements, and very large functions, you can possibly break common patterns into utils and reduce size of your functions, also you can use switch case instead of if else, that way code is more readable and clean. For Pieces, one idea is to separately init black and white pieces as a hashmap, basically two hashmaps, that way it is easier to track those pieces and reference them.
