Does someone here have a not so broken Robot Adversary, and could try this?:
- new game
- walk around with your king and get checkmated on purpose
- press Trace Back
- robot arm takes back 1 move
- chesscomputer becomes unresponsive: leds are still on, it still beeps when you press buttons, but doesn't do anything else. You need to turn it off and on to get it to become alive again.
