Feel free to post several long games where the computer attacked a GM in a real way. The rebel game was one example. I await others. I've been watching these games for a long time, and _I_ haven't seen the computers attacking the GMs... So when that does happen occasionally, it most likely _is_ serendipity. A monkey will attack if given enough chances to move the pieces around... > >> >> >> >>> >>>Here is one recent example. >>> >>>Rebel Century 4.0 - GM Loek van Wely >>> >>> >>>1. e4 e6 2. d4 d5 3.
