RobertT: without the exchange
Tokumoto: ahh
RobertT: ok, the game choice of c7 is more solid and better for territory

RobertT: d5 isn't dead and still has room to run out

RobertT: this was the big suprise move of this game
Terranigma: Was also surprised that w didnt just play Q10 actually...
RobertT: this is the most computer like move we have seen from AlphaGo
RobertT: but this move breaks the principles of the opening that humans follow
RobertT: it is similar to the first game opening
RobertT: when AlphaGo pushed from behind on the 4th line
RobertT: now AlphaGo shoulder hit a 4th line stone
RobertT: still very suprising how well this move works with the A weakness
RobertT: well that's all I really have for this game
Tokumoto: thanks a lot
Roybie: thanks RobertT

RobertT: so black takes the top move
RobertT: so that means white has to do something about the center
RobertT: since it was treated kind of like miai
Terranigma: anyway yeah that looks good to me
RobertT: its hard to think of Lee Sedols mistake because both of the players are so much stronger than me
Tokumoto: that perspective is refreshing to me...
RobertT: its hard to say but maybe a cho chikun style of game might work better vs alphago
Tokumoto: Thank you very much for the review
RobertT: one problem he had this game
RobertT: was that he waited so long to deal with black that it became almost impossible to deal with
Tokumoto: he looked so cautious and conservative in the opening
RobertT: he did better in the first game when he turned the game into no one having territory
RobertT: or a low territory game
RobertT: first game the point difference was closer to 3.5
RobertT: this game the point difference was closer to 10.5
RobertT: and the first game Lee Sedol was winning for a good part of the middle game
Tokumoto: because of the huge territory on top
RobertT: this game AlphaGo seemed to be in control the entire game
Tokumoto: I see
RobertT: well this game Lee Sedol actually took more time in the opening (though still not as much as a normal tournament game with these time settings)
RobertT: he actually went into byo yomi this game (though only in endgame)
Tokumoto: right
RobertT: in a normal tournament vs humans, Lee Sedol would be in byo yomi starting middle or part way through middle game
RobertT: one thing I noticed about AlphaGo though is it plays a very consistant speed and fast for the time settings
RobertT: it almost didn't go into byo yomi this game
RobertT: and played much faster than Lee Sedol when choosing game changing moves
Tokumoto: right.  about 70 seconds per move
]
(;W[hn]C[

-- chat --
RobertT: but the problem is
RobertT: after this move
RobertT: AlphaGo was able to get a more favorable position going into middle game
RobertT: saying that white might not have time for this move
]
;B[om]C[

-- chat --
RobertT: black can ignore
RobertT: after this
RobertT: the game is hard for Lee Sedol
RobertT: because black has a HUGE top moyo
RobertT: and whites territory is relatively small
Terranigma: your direct p7 for w suggestions looks good tho
RobertT: and blacks stones are almost all strong now
RobertT: the only weakness is the f8 group
RobertT: which isn't very clear
RobertT: to count the value of the move
RobertT: we have to compare
Terranigma: I liked alpha's response to G17 tho -- would have pissed me off as w anyway
RobertT: not really
RobertT: if white could invade and live
Terranigma: true
]
(;W[re]C[

-- chat --
RobertT: I thought white was going to start the attack on the center immediatly
RobertT: so instead lee sedol took this very big move
Tokumoto: so G17 was in Sedol's mind for a long time?
RobertT: this move is roughtly a 20 point move like we saw in the game
RobertT: yes
Tokumoto: right.  Michael said that
Terranigma: was move 70 poorly timed perhaps?
RobertT: this is the largest move on the board. the only other option is if something is more urgent
RobertT: the only really urgent thing is the attack on blacks f8 group but it is hard to find a way to profit from it right now
RobertT: so it seems ok to leave it for now
Roybie: was there a way for white to use an attack on that f8 group to prepare better for the G17 invasion? when he made that invasion it seemed a little lacking in support to me
RobertT: instead of this
RobertT: it would just be better for white
RobertT: so this seems like the deepest white can go with so many black stones
RobertT: and with whites small weaknesses
Terranigma: thanks
RobertT: np
RobertT: anything else?
RobertT: alright, if there's nothing else I'll take my leave.
Terranigma: ...speak up, people!
Tokumoto: Thank you again for doing this
Terranigma: hehe
RobertT: hope to see all you guests registered and enjoying this game in the future :)
RobertT: and hope this helped you understand the game a little more
Tokumoto: yeah, guests, it doesn't cost anything to open an account
Roybie: except all your free time

RobertT: black takes this time to defend his last weak group
Terranigma: F11 is another very deep looking move
RobertT: this game is very hard for white because white is short on territory, nothing to attack and no moyo to expand
RobertT: whites only option is to invade
RobertT: if white cant invade, it's game over
