title: Connecting a Chess Engine to an Existing GUI made with Javascript
body: <p>I have written my own GUI for playing and teaching chess. The GUI was written using HTML for the appearance, and JavaScript for the behavior of the pieces. Currently the program does not follow any of the rules of chess. It is up to the user to follow the rules of chess correctly. This allows the freedom to set up illegal positions or move the same side multiple times. This is very useful when trying to teach chess to beginners. </p>
  
  <p>I am now looking at the idea that I would like to hook my program up to a chess engine. I haven't a clue on how to go about this. Most chess engines like StockFish or Rybka use a UCI for communicating with the GUI. I don't know how to make my program UCI compatible. I am not interested in writing my own chess engine, I would simply like to download an engine and have it interact with the GUI that I have written.</p>
  
  <p>My board is made up of div tags, the pieces are just PNGs that can be dragged and dropped around on the board with complete freedom independent of chess rules. Ideally, I'd like to be able to set up any random position on my GUI, and have that position sent to the engine for analysis, with the best move recommendations returned. I don't even really need the program to move the pieces on the board for me as I can do that myself. </p>
  
  <p>Does anyone have an idea of how I might get started on this project?</p>
