Make a move on the chessboard below and the board will retrieve all games in Chess World Championship history that have reached that position. Move order does not matter, positions may be reached via transposition. As such you may enter a FEN string in the textbox below the board and click "Load Position" to see if it's ever been reached at the highest level of chess!
Clicking on the game in the results area to the right of the board will allow you to view that game in it's entirety. I hope you have as much fun with this tool as I did creating it!
