This is taken from the eighth game in the sanjubango played between Ota Yuzo (White in this game) and Honinbo Shusaku (Black in this game) in 1853. I like it for pure "wow" value. By move 41 it is clear that Shusaku is handing Yuzo a severe beat down, and he resigns after move 123.
It's not too bad yet, but Black is clearly developing faster and on a larger scale.
White is spending too many moves on the bottom while Black gets much thicker towards the center.
Suddenly Black can open up a three way attack on White's weak groups. Even if all of White's groups survive, the amount of profit Black will gain from attacking is unbearable.
Sebastian -- What does the title "FM3" stand for?
-- Oh, I realize now, after I read FHayashi's comment in the MetaDiscussion. I agree completely with him that it would be better to spell out the title, and be it only for dumb users like me.
-- For dumb users... FM3 means "Favorite Move 3" [1]
[1] Hikaru79: I find it ironic that you're calling them 'dumb users' and yet you're wrong yourself. It stands for Favorite MOMENTS 3.
