There really is a gap between a strong dan-level amateur and a pro player; pros routinely give large handicaps to amateurs to allow them a fair chance to win. Those of us who watched the game can say that there was a marked improvement in quality as Mogo was given more tine to work with. The pro did not use all 60 minutes on his clock; I believe he used about 10 or 12 minutes. The game is only a single data point, but he indicated that he might have difficulty winning with 8 stones as well; Mogo was actually ahead by more then 1.5 points, but in classic montecarlo style, did not maximize the win; it is indifferent to the size of the win.
I'll back David Doshay: in ten years, a supercomputer will play pros on an even basis - provided that Moore's Law continues to increase the power of supercomputers. I also believe that some algorithmic improvements, which previously were not useful, will be of value with more powerful processors. We have a saying "learn joseki, lose three stones". Lower-level players learn book moves, but do not know how to preserve their advantage. With ten-minute games, Mogo was in that state - unable to preserve the advantage. When given 60 minutes, it had a playing style which could generate joseki plays at need - but it consumed a lot of time. This is interesting - given enough time and processing power, an algorithm which knows nothing about joseki or opening books will converge to joseki. These are plays which many very smart humans have studied for thousands of years; it is not surprising that they should be optimal or near-optimal.

I think events like this are great. They generate interest and excitement and are great fun. But they have very little scientific value. They are wide open for speculation, non-objective analysis, etc. Often strong players fail to take matches like this seriously because they are exhibitions with nothing particular at stake. I don't know if this was the case or not but I know it is happens. Also, it seems silly to me to find super strong players only to heavily handicap them. What's with that? I know of course why, nobody cares about an exhibition match with an ordinary player an thus it has value. But it really underscores the nature of this kind of exhibition, not really a significant scientific experiment. No serious conclusions are possible. It's also rather silly to rank moves and not performance in general over many games. Such and such a move was a 5 dan move, this other move was a kyu level move, etc. This is a sound bite to make people happy but isn't very quantifiable. Nevertheless, I have high praise that such an event took place, it's always super-cool to be able to utilize such a powerful machine and this was a good excuse to do so. I am left relatively confused about the outcome however. Someone gave a computer a bunch of stones and it was able to beat a strong player. Is that supposed to be exciting? I think I would simply be embarrassed that it was believed that so many stones were necessary to even the match. (Of course compared to a few years ago, this is an impressive victory for a computer go program, although only a single data point.) I hope I don't come across as being critical, I think this was a great idea and such matches should be arranged whenever possible. I just get a little embarrassed when too much significance is made of it. - Don On Fri, 2008-08-08 at 10:13 -0400, Robert Waite wrote: > I was in the KGS room for a couple of hours before the match and a > couple after.
