I created a Facebook page called Chess Club Live and would direct fans of my page to register on WebChess X.Then the unthinkable happened I closed my chess website WebChess X because maintaining and running it was taking so much time and there were better alternatives like Lichess, which was and still is just awesome. My original web app is still running on the web archive just in case anyone wants to have a look. Over the proceeding months I began refining the app. Another unique feature was adding the countdown timer and the flipping the board so that you solved the position from the right point of view of the player to move, believe it or not this was not standard, as the standard was to solve from the point of view of the white side even for puzzles with black to play, like newspaper puzzles or CT-ART and other puzzle apps were working at the time. The guess-the-move app had three guesses before it revealed the answer and I built that into my app as three strikes and the test stops or you run out of time, 3 strikes and you’re out, that was unique feature as no chess puzzle app in the world had ever done this at the time. It had to be just that move because their answer would reveal their ELO and whether they were human or a bot. The app I built was simple it randomly selected a position and asked the user to play the winning move. The app recognises FEN strings from pgn files of game fragments and matches the move played with the move string loaded. I also used some open source code called LT PGN VIEWER by Lutz Tautenhahn which had a guess-the-move app, problem board script. So I wrote the code in PHP utilising my database of over 10 million chess positions. Why not create a test which randomly quizzes users with chess puzzles but make it time constrained and rated so I could validate that the ELO of the user was still consistent with the results they were getting. I spent a few months in mid-2008 racking my brain as to how to solve the problem. I opened my chess server and found it was thriving but had a problem with some users cheating. It was in 2008 when I had finished my chess server WebChess X using open source code WebChess.
