Tan Xiao 7p and Xie Shao Bo 2p

21st Samsung Cup final game 1

Translated by Daniel Hu 4d


Today the two players are quite well-known. Number 1 and 2 in China. Ke Jie's historical record is rather good, 4-0 against Tuo Jiaxi in proper tournaments, 0-1 in a preliminary.

Tan: Tuo told me he felt a lot of pressure

Xie: maybe he was just being polite, he probably has confidence

Tan: Well, of course, you need self-belief.

This is the same as the Ke Jie - Lee Sedol game but with colours switched.

;B[ni]
(;W[cl]C[but W is saying that O11 isn't severe]
(;B[pi]C[so B continues over here, the same as that game aginst Lee Sedol. Except that game was Ke Jie holding white.

Xie: perhaps he thought W was very satisfied

Tan: maybe he thought it was close, but he eventually lost.

Xie: but initially he was far ahead

Tan: he's just saying he is confident, not scared either as black or white]

;B[rn]C[Up to here it is exactly the same as the semi-final game 2.

Xie: At first glance, it looks like B is good, with a lot of territory on the right.

Tan: well the thing is that W didn't have much territory there anyway just less than 20. And W still has 5. B got a few. And W got a move on the outsde (L17), so it's just a question of who is stronger in the centre.


__ 
Leelabot thinks B is well off now despite the 7.5 komi, compared to thinking W far in the lead before C5]
(;W[ml]C[I feel that this is better than Ke Jie's choice in the previous game. This feels more urgent.

White must have also studied this position.]

;W[ce]
;B[ed]
;W[dc]C[before alphago, your teacher would tell you or for playing like this.

Xie: they say computers have a direct analysis: without these moves, W is out into the centre, but now, B restricts the access. And it feels just this is logical.

Tan: well, C14 was previously soft, but now I has become hard headed, and B has also lost out on territory, but whatever you say, B has got an extra 2 stones on the outside.]

;B[hc]C[if B still returns here, were the D15, E16 exchanges really a good idea?

it seems like B was scared W would H17 in sente instead of L8 otherwise

]
;W[nc]C[Xie: are these white stones in trouble?

Tan: they probably shouldn't die. But if you play slightly wrong, they may.

Xie: In this sort of position, I am quite scared as too live, you need to depend on the crude exchanges K16, J17. And what if even then you can't live?

Tan: In this position, those exchanges are ok, as B also made a bunch of crude exchanges are D15 and E16]

(;B[hq]C[how do you think the position is?

Xie: I think it's better for black than the last game.

Tan: Of course, in that game, black collapsed after a few moves.

At the moment, in points, B and W has 2 points

So it is about how much B can make in the upper centre.

Xie: I made a count earlier and thought B was good as I thought the upper centre could make quite a bit.

Tan: I agree. But W didn't seem to play any bad moves. Perhaps K8 was still too slow and should have protected the top. Somehow B played a few moves and surrounded W. And W had to live particularly painfully.]
;W[kp]C[This move fears B N6 first, as even if H5, it is still hard to disconnect L4. This move is on points.]
;B[ho]C[At 1/2 mill sims, Leelabot favours B 54.55%]

;B[bm]
;W[bo]
(;B[fo]
(;W[hl]C[My feeling from this move is that W thinks he is behind. W thinks that normal play isn't good enough.

Xie: But this shape feels so weak. On one side is 3 space, the other is 2 space.

Tan: purposefully leaving weaknesses. And yet sometimes this is a better strategy.

Xie: you mean then your opponent doesn't know which one to attack.]
(;B[no]C[Sometimes the player's moves can seem very strange to observers.

Actually from the last two moves, I think you can tell how the players are feeling about the game.

Ke Jie isn't interested in cutting.

One is playing more like overplay, the other is playing more stable]
;W[kn]C[Xie: like this, at least it feels like W's intention has been fulfilled

Tan: yes, actually B can exchange O5 for L6 anytime.]
;B[jo]
;W[ko]
(;B[mn]
;W[jn]C[Xie: Ke Jie's endgame is very strong, so I suppose he is confident.

Tan: W gains again these few moves, W is more solid.]
;B[fl]C[It feels like B made himself thin so he has to protect]
;W[mh]
;B[lh]
;W[mf]
;B[lg]
;W[ne]
;B[md]C[W captures in sente. I feel that the sequence for H3 black definitely lost out, clearly lost out.

Xie: W got the corner and B's centre isn't so big as expected

Tan: and in a moment O11 might be killed]
;W[jd]
;B[je]
;W[ch]C[In fact up to here, I feel that B's advantage has mostly disappeared.

__
leelabot disagrees: 54.59% at 1.5 mill
__

if B loses, O5 can be said to be very at fault. If he just attacked like a female player, I feel like W would just collapse.

But male players don't like to pounce on weakness so quickly.]
