I have played chess but wasn't much good at it - no real strategy, just off-the-cuff moves. In an effort to try and improve my game, back in the early 80s, i bought a small electrical chess game with differing levels of difficulty computed into it.
I was beaten by the machine more times than i cared to count - even on the 'beginner' level, but one day i thought my luck had changed when i captured it's queen. However, a few moves later, the machine moved it's queen!!! I had taken it but it had reappeared on the board.
I promptly gave the game away:-/
