Roatta Software (c) chess parser
This is a chess notation visualizer. Select any text which is a chess game notation (PGN or FEN), right click and choose small or medium board from "Roatta waayyy!!!" in the context menu. A window with the game will be opened. There are available such functionalities as play forward, backward, last and first position, or just play without clicking. Switch sides is in the bottom left side of the board.
If the window is empty, move it and it will be updated instantly. Hope I'll find a way to fix this later.
