Chess ends up boring me because it's too easy, only reason I stopped competing in high school. I like to think of Chessmaster as the perfect glutton for repeated defeat. Most humans tend to find something less impossible to do and up just as bored of chess as me. Not sure what Chessmaster's real ELO is, it's not 3003 as advertised. Though it also has really stupid moves in its opening book it's programmed to play(1. ... e3?), might be the developer's fault.
