I registered a computer account on the Internet Chess Club (ICC). I’m using the WinBoard GUI to play MadChess against human opponents. I know the ratings of computer chess engines are not well calibrated to the ratings of human players. However, MadChess is exceeding my expectations, winning its first twenty games and counting.
In case you’re wondering, I am not violating ICC rules. I registered MadChess as a computer account. All ICC players have the option of blocking computer players, if they wish to play only human opponents. See ICC Help : Computers for details.
See Versus Human Ratings for MadChess’ rating against human opponents.
