I began a game in a tournament early in September 2011 and two weeks later I conceded defeat and resigned. In the return match which began in late September I quickly gained a winning advantage and guess what.
Yes, that's right, my opponent began to use six days and twelve hours on every single move. So I decided to set conditional moves to cover every eventuality to speed things up. No good. Even with conditional moves my opponent is still stalling, with the added bonus of occasional vacation time.
I've often complained about slow-timers but in all the 1407 games I have played here on chess.com I have never come across anything like this.
