I think I saw the same guy playing last weekend, and assumed it was 777. I saw him get a time of 9:13 or something, and again he didn't enter his initials. Out of the 3 pier players that can play that fast, I think the style definitely most resembles 777's.
Following links from the ustream page, I notice that Pier21 has links to youtubes of many of these sessions with player names branded on to the clips... http://pier21.sakura.ne.jp/pier/
According to their twitter feed on the stream page, 777 is playing now if your interested PS You can go directly to their youtube, their latest content is under the user Pier21kodaira, with older pier21 accounts from a few years ago. Some of their latest content is their Masters tournaments (qualifying and finals) as well as their hand/screen shots of top players.
Nice. I'm the guy chatting with you alone in that room btw! Edit: The 20G round ended with an early top out. Bed time.
just watched 777 getting a 9min16 Gm on the "today's ranking" screen, 3 scores from him, all three under 9min05 that guy is good
So apparently they're doing this every day now. It's on. I suppose I'll stop bumping this after this post. It's on pretty frequently.
Well, I lied. I'll bump it again. I'm pretty sure they're doing the masters thing now. 8 players at once with commentary. RIGHT NOW! For anyone who happens to be browsing. Edit: They seem to be doing another round? I don't know how this works. But there are eight players again.
