Gosei - Kono Rin starts 2-0; can Iyama pull this out?

Kono Rin won game 2 yesterday. Game 3 arrives already on Friday. Anyone know of other examples of two title games scheduled in the same week in a Japanese tournament?

Curious enough to see new scheduled. This year's Meijin will have five days between rounds (compared to the Gosei 4 days between rounds).

The previous Oza had two days between rounds, since they did the first two rounds in Taiwan.

Could this "speeding up" of play be part of a plan to make top Japanese players more competitive in the international tournaments?

Perhaps it is to the advantage of younger players, who, if they are good enough, can start earning significant money earlier in their careers.

I assume that it is mainly driven by Iyama's busy schedule.

Coincidentally, the 2nd game is one I picked to play through yesterday.

It's an interesting game. I wonder how many of us would have had the patience as white to let black's moyo get this far. Maybe take a minute and think about the next 3 moves...

Iyama wins game 5 W+2.5 to finish a comeback and keep the title 3-2.

Wow, from 0:2 to 3:2.

Reminds me of past matches in which one player had to survive three kadobans to win, e.g. the 7th Kisei title match.

So Iyama now has a chance coming up to get back up to 6 titles with Meijin starting next month.

This is something that I've been interested in for a week or so. What would be the best way to figure out whether the better player is more likely to win in a "match point" game than in a non-crucial tournament game or in a standard game? It would be easy enough, although tedious, to add up each players record in the relevant games of the title-matches he has has competed in, but then once you have that information what do you compare it to?

I can't say it's the best way... but assuming I had all the necessary information, I would build a rating system similar to the one developed by others elsewhere on L19 for pros, use that to calculate an estimated winning percentage for a player's match point games. Then I would compare their actual performance to that estimation to see if there is a consistent deviation from that expected result.

Okay, that's pretty elegant. Has anyone released the underlying rating numbers that would allow you to infer a winning percentage? I see a couple "100 top pro" lists a year, but as I recall they just publicize the bare ranking. Maybe they'd share if I asked.

The potential for the best data would be through the professional organizations themselves, though I don't know how well they collect it, or what they do with it. A good attempt at it using GoGoD was made by typohh a few months ago, though he only published a limited set for space reasons.
