Try shredder chess, not only it is more human-like, but his "blunders" are very interesting, because if you spot it you often have a chance for spectacular ...[text shortened]... Of course, not on its full strength, then it does spectacular tactical attack on your skin )
CM personalities have been my only opponentes for a long time, and I think even though it really seems artificial, above the 1600 level, it begins to make only small blunders (like giving a pawn away with a 2 move combination, or moving it's king before castling, etc), and plays really
accurately while defending. (at least according to my level.)
here's a game I drew from a very nice "positionally won" position where a 1560 rated personality (actually it's objectively stronger than the 1650 personalities, according to it's settings. his rating is miscalculated. anyway) begun to defend very accurately after the loss of a pawn.

I just made two single inaccuracies because of time control (I had 4-5 minutes left on my clock) in the middlegame while building up the attack and I got punished for it, being the side to defend now. if you analyze the game a bit, beggining from 24...Qh6, all the moves (including the insignificant looking move of the h pawn) are prophylactic. (by the way, 41.Nxe5 was a game losing blunder from me, but my opponent failed to take advantage of it.)
the nice thing about CM is, eventhough it plays artifical blunders, above 1650 or something, you have be quite accurate to punish them.
note: all these statements are for long time controls. I don't play any games slower than 90' 30'' ore 40/120' against CM. In fast time controls, people say it makes really gross blunders up to 2000.
