Life In 19x19

5th round 2nd game:

Ke Jie beat Li Zhe by 2.5
Peng Liyao beat Zhou Ruiyang by resign

So Ke Jie straight through to final, Peng vs Zhou decider in a day or two.

Zhou played more Master-style moves with the avoiding avalanche joseki like vs Jiang Weijie that Redmond commented but Peng played one not 2 space high pincer when approached.

3rd game is live now with more Master style from Zhou in that he played press after low approach to 3-4 and distant pincer and then tenukid twice. One stone (:b17:) of his resulting group ended up looking misplaced though so I feel it's not so good, I wonder how Master handled similar situations. Or maybe Master wouldn't tenuki so much because white already reinforced the 4-4 behind the pincer (:w6: in 1st diagram) so counter pincer is less effective. I can't yet recall a Master game where it defended the press group following the attack at 14 from the corner (there was #33 vs Gu Li where it was attacked from outside and played push instead of dame connect).

The marked stone below isn't totally useless as it all but stops the peep at a which could be a nice sente for white and help his side group come out, means black can deal with the white double hane b-d, and is also a vital point for building eyes (and indeed Zhou did later allow that group to get cut off and live inside with an eye there), but I can't help feel it would be better placed at e or somewhere else.

Also the marked stone does mean black has a good answer to white cutting across the knight's move without needing to fight the ko (with 8 at a):

Edit: And Zhou indeed lost, so the final is Peng Liyao 6p (goratings #30, in his first international final) against Ke Jie.

Edit 2: Analysis of the Master opening: http://www.lifein19x19.com/forum/viewto ... 18#p219218

The best-of-5 final will start on 12/18 and then 19/21/23/24.

Sorry for the misinformation. The final will start on 12/20.

Game is live now, is Ke Jie in trouble?

No

The third game, and might be the final one, is this Saturday, December 23.

Ke Jie won the second game as well. He took all 4 corners and then lived with a big group in the centre using some nice counterattack against the surroundings.

Peng had much better chance yesterday comparing to the first game, but didn't handle it well after white crosscut in the middle. With Ke Jie holding white in Game 3, the chance is pretty high that the final will be over tomorrow.

Ouch, Ke Jie lose by 0.5 point so they have to continue game 4 on Christmas.

Probably because that game had practically no middlegame and that's where Ke's greatest difference in strength lies. It was basically play some joseki on a side, play two 3-3 invasions, resolve a ladder, one side invasion jumps out to safety and now >200 moves of endgame.

4th game, I think we can conclude that Ke Jie has absolute faith in AlphaGo Master.

Update: now I have to watch tomorrow too

Peng won the 4th game by half a point as well so it goes to a deciding fifth game tomorrow. Ke is white tomorrow, but could he let this title slip from his grasp?

Ke Jie actually ended up black for the game 5 since they always re-do for the deciding game of a series.

Ke Jie won the final game by half a point so wins the first Shinyao/ENN cup.

Ke Jie's strategy to play fast and use time pressure work this time
