Okay, I was just playing a game on Live Chess and I was getting ready to win. But this guy got me in perpetual check. I offered him a draw, thinking that the game would be one anyway. However, he declined and began checking me. I kept going, thinking that he just didn't know. To my surprise, I found out that no draw was made. He continued to check me...and I checked and saw that I was down on
time. This guy was trying to run me down on time and get a win. Unfortunately for him, I'm a fighter and don't give up too easily. I finally got him to make a wrong move and win the game...after 606 moves. My question is: Why was he able to do this? I thought that a repetition of position 3 times resulted in a draw. Thank you very much.
