to follow up on my last post about the chess, one thing that really stands out for me is how many times both players, in the analysis of computer-assisted observers, have failed to make midgame or lategame moves that would have set them up for a near certain victory. i would not be surprised if it is the case that players who've reached this level are fairly risk-averse overall and all too willing to accept a draw rather than lose (and perhaps look foolish) and although i don't know this to be true it is quite possible those moves were unorthodox and risky. still, it says a lot to me that our greatest human players can fail to glimpse all of the possibilities once they've been substantially narrowed, even as they clearly see so many of them; that even they are quite fallible. i wonder how much of the admixture each contributes to these failings, between risk-averse play, failing of ability, and over-reliance on known lines of play causing unorthodox unprepared-for lines of play to be dismissed out of hand (out of mind...). have our best players perhaps become more 'robotic' than actual (with figurative license) robots?
