Thank you, Hiroshi.

Exactly the komi was 0.5 pts to make W win if draw (common setting in 
handicap games).  Japanese rules were used and time setting was 25 
minutes sudden death (but flexible :).

Before wasting ko threats, ie, after losing some pts by the moves on 
lower bottom side, Zen was behind and had no chance at all.  B had to 
cut at M5 before J3 to prevent W K7.  Perhaps, reserving M5 was the 
game.

After the game, Kazunari Fujisawa 8p (a regular member of the program; 
http://www.nihonkiin.or.jp/player/htm/ki000209.htm) told me that some (I 
guess around 3) reverse komi might made Ishida lost the game.

Below is the game record with time.  Ishida 9p used pretty less time 
than Zen :).

More human-vs-Zen matches are planed being broadcast by Niconico Douga 
(http://www.nicovideo.jp/) in next month (as events of JAIST Cup and a 
symposium at UEC).  Although Niconico Douga has no Japanese registration 
page, not few Westerns (such as David :-) have successfully registered 
using machine translation, such as Google.
#NB: Most (all?) animes are limited to premium (payed) members.  :p
