GN[British Championship - title match game 1]PW[Andrew Simons]PB[Sam Aitken]WR[4d]BR[4d]DT[2018-07-21]C[BGATeach [-\]: Morning All
BGATeach [-\]: This is a clone of todays British Championship Game 
BGATeach [-\]: I am Matthew Macfadyen, I will be running this clone as a discussion of the game
BGATeach [-\]: Due to start at 10.30
BGATeach [-\]: Game will break at 1 for lunch
Nyanjilla [-\]: times are GMT/UTC + 1
BGATeach [-\]: Players are still organising their coffes
Nyanjilla [-\]: important task....
BGATeach [-\]: I am in the conservatory next to the game, so can answer some questions about the players' movements and demeanour as well as their moves
BGATeach [-\]: OK, Sam to start
]
;B[pp]
;W[dd]
;B[dq]C[BGATeach [-\]: Matt Marsh is recording, he will enter the moves sideways on, so we can expect them to start in the wrong corner.
]
;W[pd]
;B[cf]C[BGATeach [-\]: I have not been following very recent trends, but the left side shape here has been very carefully studied.
BGATeach [-\]: We can expect andrew to have done the homework.
]
;W[co]C[BGATeach [-\]: We can also expect him to spend a lot of time on the opening
]
;B[fc]C[BGATeach [-\]: White has chosen a busy version, arguing with the black formation before building a white one
bert [?\]: meh. it is just another starpoint opening expecting to induce immediate sansan invasions
bert [?\]: sorry, joking a little
BGATeach [-\]: Only one corner left to do immediate sansan on
Aasumi [8d\]: I expect a D14,F16 or E4
BGATeach [-\]: Some players would like F4 here
BGATeach [-\]: Also reasonable is E15, expect black C17 then maybe F4 or G4
r0n1n [3d\]: i feel d14 has been more popular than e15 lately
ibd2 [?\]: I thought e15 has fallen out of fashion
BGATeach [-\]: There have been many different fashions. I fear that people will look at Alphago's move and stop experimenting with the others
r0n1n [3d\]: surely it doesn't mean we shouldn't consider this move as an option
]
;W[ep]C[Aasumi [8d\]:  as expected
Aasumi [8d\]: Black can either go E3 or C4
]
(;B[eq]C[BGATeach [-\]: When I was young nd reckless, I would push and cut here - there are black stones in both adjacent corners
]
;W[fp]C[ibd2 [?\]: E3 only if we want to stay true to AG's school ;)
Aasumi [8d\]: What about trying E3 instead of F4
]
;B[gq]
;W[fd]
;B[gd]
;W[fe]C[BGATeach [-\]: The game has gone another way
bert [?\]: i there any particular reasoning behind the choice between f16 or d14 
BGATeach [-\]: Black will now expect a position on the top side, and White will have most of his goodies on the left. 
Aasumi [8d\]: White can also go to the right if black chooses to go D17
Aasumi [8d\]: Most likely Black will e17
Aasumi [8d\]: Hmm instead of B16 I think E18 would have been better
]
(;B[ec]C[BGATeach [-\]: When the corner is settled, first move on the right side will be big
]
;W[dc]
;B[dg]C[BGATeach [-\]: This pattern was common in the ancient (400 year plus) Chinese games
BGATeach [-\]: At some point in the fighting White will want to play a slow move at D18.  He could try doing it now, though the normal idea was C15.
lolove27 [4k\]: is it worth for white as B17 seems to be rude?
]
(;W[ce]
;B[be]C[bert [?\]: i thought b17 was left for later
BGATeach [-\]: B17 happened lots in the very oldest recorded Chinese games. They were obsessed by invading every single point possible
BGATeach [-\]: now D14 no choice
]
;W[df]
;B[bf]C[Aasumi [8d\]: B14
Aasumi [8d\]: White can choose to go out at E13 first before comming back at B16
BGATeach [-\]: I think White should D18 now, not block at B16 cos it doesnt work
Aasumi [8d\]: e13,d12, j16
BGATeach [-\]: Yes, Aasumi, better not try to defend the corner when it is so difficult
vagrant [2k\]: if white b16 now and black clamps at b17, is a15 better than a16 for white?
vagrant [2k\]: i understand its probably still not good enough
BGATeach [-\]: Notice that Black must not play E14 too soon. Tat spoils his corner possibilities
Aasumi [8d\]: if he gets clamp
vagrant [2k\]: it enables the cut at c13 though
BGATeach [-\]: Yes. I was just pointing out that the 'automatic' looking forcing move at E14 should be left out
Aasumi [8d\]: Possible moves,C11, D11
BGATeach [-\]: Yes, White wants to save the honour of his E4 F4 stones
BGATeach [-\]: Sorry, finger slipped, that R4 stone was nothing
SelfAtari [2k?\]: disappointed
adsdada: who would play that way
adsdada: u hane with b
Aasumi [8d\]:  J16,G15,G14,H14,F14,J15
BGATeach [-\]: I have a quarrel with andrew symonds at times like this. He knows all the joseki moves, and knows that they are all almost equally valuable, but he has only 3 hours on his clock, and often spends 10 or 20 minutes choosing. I dont believe the time is better spent here than in 100 moves when he has to count  liberties accurately
adsdada: wait this is played with3h?
BGATeach [-\]: Yes
Aasumi [8d\]: The Byo yomiu ten mins each is more than enough 
Aasumi [8d\]: + there is 10 byo yo mi
adsdada: only 1game per day i guess than?
BGATeach [-\]: Aasumi, your sequence is good for black when F14 is needed. so White must wait.
BGATeach [-\]: usually, when you have a really good shape attack available, it is best either to play it or to do nothing and wait until the shape comes good.
BGATeach [-\]: Anything better that playing locally bad shape as a compromise.
]
(;W[bd]C[BGATeach [-\]: This is the 400 year old line
adsdada: 20 minute think :>
]
;B[fg]C[BGATeach [-\]: Black has a tactically sound move at B17. F13 feels a little odd.
BGATeach [-\]: There is a big point for both around C9. Now if Black plays it then F13 will look a bit redundant.
BGATeach [-\]: Maybe Black wants the long extension to C7, so as to attack the white wall below??
Omicron [1d\]: he is trying to make white play G15
]
(;W[eh]C[adsdada: g14 instead of g15
AlfGO [1d\]: b d12 ?
adsdada: e13
BGATeach [-\]: Looks like White plans to settle the corner quietly. Perhaps this is his idea??
]
(;B[dh]C[BGATeach [-\]: Sam didnt like the look of that. Now the two stones at E12 and F13 both look odd. I wonder which of them is more useless?
adsdada: w may try to find smth at g13 now
BGATeach [-\]: The corner has become small for both, since Black is now almost alive on the side. When he was still weak on the left side, Black could invade the corner and make eyes there, saving himself the need to defend and so justifying  a 10 point territory move in gote. 
Xorax [-\]: just d11 now?
]
;W[id]C[BGATeach [-\]: Looks a good direction, but he cant follow c11 at c10.
BGATeach [-\]: The game move looks natural
BGATeach [-\]: White has to be careful of his liberties:
Xorax [-\]: hope this doesnt happen ( :
ctdogpdf: so is there any option for b ?
BGATeach [-\]: Black can also play B17, try to steal some endgame before sacrificing the F17 stones
BGATeach [-\]: Or slug it out in the centre:
]
(;B[he]C[BGATeach [-\]: Sams move is similar to the last one I showed. He expects to see H18, stealing his yes and his shape, and hopes to counterattack later on
BGATeach [-\]: his eyes
adsdada: h18 feels like aji keshi
BGATeach [-\]: H18 is a strong and violent attacking move which steals Blacks eyes and prepares to build a big territory at the top.
adsdada: but does b have a good way to make eyes there?
adsdada: and i want to keep the g17 aji
BGATeach [-\]: White will only be interested in cutting at G17 if it is necessary to live with his corner stones
adsdada: or damezumari g16
BGATeach [-\]: Or if he connects the top side together by doing so
BGATeach [-\]: H17 is simpler as a peep, but Black has much better eye potential at the top side
adsdada: why play there at all
BGATeach [-\]: Play there to stop Black from J18 or J17 to settle his group
]
;W[gg]C[adsdada: i feel like b helping white build the left side by playing either of these
BGATeach [-\]: Black is in danger of having a huge eyeless lump straggling across the top of the board, making it unsafe for him to invade O17 or to attack C7
adsdada: topside*
BGATeach [-\]: Now black L16 looks attractive
AlfGO [1d\]: Bl j15 pushing again and then g12
BGATeach [-\]: J15 will get out, but very expensive. there is a big gap between J16 and Q16, and black wants to play in there with attitude and aggression, not just invading with a weedy 2 eyed group
BGATeach [-\]: How will White answer this??
]
(;B[ie]C[BGATeach [-\]: Black decides to spend the money and escape to the centre
]
;W[jd]
;B[je]
;W[kd]C[BGATeach [-\]: As Black, when you get a group like that one at the top, it is a good idea to plan exactly what shape you want to finish up with, and see which of your opportunites you can keep.
BGATeach [-\]: Sam has decided not to try to make any eyes at the top, but to get out to th middle. 
BGATeach [-\]: He has not stoppedD18 from being available to white to prevent B17 from killing the corner. And he has not filled the G15 liberty.
]
;B[fh]
;W[hb]
;B[gc]C[BGATeach [-\]: I do not think the white corner is in any danger unless black can play H17 in sente, so why is he so keen to surround it?
]
;W[gf]C[BGATeach [-\]: Now I expect K12, or near there, hoping to have good follow ups at e.e. N16, C7 and B17
marmoset [?\]: Can you switch on the move numbers
KirbyZhang [-\]: hi
KirbyZhang [-\]: i am 8d
BGATeach [-\]: Hi marmoset. I just tried, and couldnt find the button - should be in 'tool'

KirbyZhang [-\]: bye
BGATeach [-\]: Hi Kirby, can you find us a good invasion for Black around O16 area?
marmoset [?\]: Does BGA Admin have to do it?
KirbyZhang [-\]: i am acually 2d
marmoset [?\]: In the main game
KirbyZhang [-\]: are they professional
KirbyZhang [-\]: i am8
RICHTERMX: look at their names
RICHTERMX: of course they are not professionals
KirbyZhang [-\]: OH SORRY
BGATeach [-\]: White C10 is very big and could become a real attack if Black ignored it
KirbyZhang [-\]: c10 is good move
BGATeach [-\]: O16 is a big move, but feels a bit slow
KirbyZhang [-\]: what is your rank ?
BGATeach [-\]: D18 is a really slow move, but it makes the corner 100% alive and threatens to escape J16 group 
BGATeach [-\]: That better marmoset?
KirbyZhang [-\]: BGATeach
marmoset [?\]: Brilliant
BGATeach [-\]: historically 6 dan
KirbyZhang [-\]: what is your rank?   :)
KirbyZhang [-\]: ok
BGATeach [-\]: I played over 100 3 hour games in British championshi matches since 1978
BGATeach [-\]: After C10 White could use E11 as a good forcing move
]
;W[cj]C[BGATeach [-\]: Now that Black is being attacked on the left, he gets another chance to ply B17 and ask whether White wants D18 or A15
BGATeach [-\]: So far, White has developed the left and the top sides without losing his corner group. Black has more work to do
]
;B[bc]C[BGATeach [-\]: Now we will know. 
lolove27 [4k\]: Could you explain the purpose of white E11 as a forcing move I don't understand it :) 
lolove27 [4k\]: to close a little bit the left side?
BGATeach [-\]: E11 would do something towards surrounding the whole black group, while forcing Black toplay the almost useless looking E13.
BGATeach [-\]: Like this:
BGATeach [-\]: Black might catch the 2 stones e12, e11 but thats only one eye
BGATeach [-\]: Marmoset, did you prefer having the numbers on all the time?
marmoset [?\]: Yes
TobyM [1k?\]: Ideally te numbers are ON on the BGA Teach game but OFF on the actual game
BGATeach [-\]: How do I organise that toby?
TobyM [1k?\]: Dunno
YZ1509 [3d\]: numbering tool F8 can be done
YZ1509 [3d\]: but you need to redo that each move,m so not practical
]
(;W[ei]C[BGATeach [-\]: Hes trying the forcing move.
BGATeach [-\]: Black can make a mess by resisting at D11
marmoset [?\]: BGA Admin has an extra move
]
(;B[eg]C[BGATeach [-\]: Thanks. I think Sam was being a bit obedient there, but maybe he has a clear vision of the end of the fight and he feels OK with it
BGATeach [-\]: As the fight continues, both sides should be spending the time (especially when not on move) to plan the black invasions at C6, O16, etc etc. 
BGATeach [-\]: Incidentally C3 is a good move for Black lower left. it stops a lot of aji around F3
]
;W[hi]C[BGATeach [-\]: Interesting. 
]
(;B[ad]C[BGATeach [-\]: Black has now very nearly finished living on the left
BGATeach [-\]: Notice that the cut in the centre does not work simply:
BGATeach [-\]: No, forget it , didnt work
]
(;W[ig]C[BGATeach [-\]: White didnt fancy the fight
adsdada: a16 doesnt feel right
BGATeach [-\]: Sam could have played A16 at C17, then White D18 threatens to connect along the top. This way white is adrift in the centre
adsdada: did w have a good move to secure the corner tho
BGATeach [-\]: And so is Black, but White has done very well on the left side
adsdada: i think pushing around f11
adsdada: wouldve been stronger
BGATeach [-\]: stronger for Black?
adsdada: yeah
adsdada: i dont see how white seals the corner
adsdada: and connecting to h18
adsdada: is too slow
BGATeach [-\]: Remember that black now has eyes in the corner, so those two stones E12 have no real ambition and White wont try to save them. Better shape for Black is E9 or C9, try to break in on the left while attacking
BGATeach [-\]: But first there is the issue of how strong the two eyeless centre groups are, and whether Black will get to invade O16
]
;B[jh]C[TobyM [1k?\]: W14 looks good to me
TobyM [1k?\]: sorry M14
adsdada: g10 now
adsdada: i dont see how b gets in a move around e9 anymore
BGATeach [-\]: Like this:
adsdada: yeah but b weak still
adsdada: so i think its fine
BGATeach [-\]: Andrew is still thinking
BGATeach [-\]: Andrew is sealing his move for lunchtime.
BGATeach [-\]: We will be back in an hour.
]
(;W[gj]C[BGATeach [-\]: Hi all, now back from lunch. Whites sealed move was the digonal connection in the centre
BGATeach [-\]: So White now has  position on the left worth 30 points minus anything Black can knock off it.
BGATeach [-\]: And Black has first shot at the top side. I expect an invasion around O16
BGATeach [-\]: A more peaceful way would be to approach at R14 and try to build the right side
]
;B[gp]C[BGATeach [-\]: Sam has quite a different idea. This builds the lower side while taking away Whites options after F3.
BGATeach [-\]: This also makes invading the left side deeply more believable
BGATeach [-\]: Among Whites many choices he can take first move on  the right side
BGATeach [-\]: Like this:
]
(;W[jj]C[BGATeach [-\]: Hes chosen to pursue the centre group for a bit.
BGATeach [-\]: Now Black is wondering how to keep some options of invading O16 while not getting too weak in the centre
BGATeach [-\]: If Black gets short of eyes, he can use the top side like this:
]
(;B[le]C[BGATeach [-\]: Once again, Sam goes for the simple clear line. White can have the top side but Black plans to make lots in the lower right
BGATeach [-\]: White can push and cut but he would need to kill to justify doing that:
]
(;W[nd]C[BGATeach [-\]: Much more sensible for White
BGATeach [-\]: Black can probably live at the top, but it is not yet biggest.
]
(;B[qn]C[BGATeach [-\]: White is quite thin at the top. Notice that he needs the L15 liberty open:
BGATeach [-\]: Black can invade the left side, but best will be to expand the bottom, encourage White to invade, then get the shapes settled there first.
BGATeach [-\]: heres a candidate invasion:
]
(;W[li]C[BGATeach [-\]: Andrew is going for the centre group.
]
;B[mh]C[BGATeach [-\]: There is some aji remaining in Whites central connections:
BGATeach [-\]: Going back a bit. I thought during lunch that Sam might have missed a trick:
adsdada: if w gets out with sente here and has a stone on the rigth side which invasion point would u pick
adsdada: between q3q2 orp2
BGATeach [-\]: All those three points are reasonable. Lets look:
adsdada: now what about
adsdada: p2 p3
BGATeach [-\]: The main reason for P2 P3 is to try to kill all, but Black needs more stones around:
BGATeach [-\]: Still no movement from the Symons corner
adsdada: so b needs a move both ot the rigth and at the bottoms ide
adsdada: :>
adsdada: w q12 looks massive
BGATeach [-\]: Q12 surrounds a very large area with a rather small probability.
BGATeach [-\]: White could try to simplify his reading atb the top by playing N16 now.
BGATeach [-\]: See what happens if White tries to cut:
BGATeach [-\]: Andrew has 44 minutes left; Sam 1 hour 35
]
(;W[qh]C[BGATeach [-\]: Almost your move, adsdada
adsdada: not sure if that is a good thing
BGATeach [-\]: This way Black has more room for eyes in the middle
adsdada: yeah i wanted to play this to deny r14 later
adsdada: and swap fast to the bottom to play the corner invasion
BGATeach [-\]: R14 is still available:
]
(;B[mi]
;W[mj]
;B[nj]C[adsdada: didnt think hed answer n10
adsdada: n11*
BGATeach [-\]: Sam plays simply again. Hes decided to escape with this group, not try to make eyes
BGATeach [-\]: Lets try a rough count. White has about20 on the left, plus 40 at the top if he plays R15 and keeps it all.
BGATeach [-\]: Black has 15 lower left, 10 top left, plus 50 at the bottom if he plays P3 and keeps it all.
adsdada: its ws game to lose
BGATeach [-\]: So Black is slightly ahead (remember komi) if everything stays where it is and  there are no invasions
BGATeach [-\]: This means White must invade the bottom at some time
BGATeach [-\]: And if white does, say at Q2 and live small and simply, then Black must invade the upper right
BGATeach [-\]: Or alternatively, if White now plays R15, then Black has one move to secure the lower area or else threaten the left side
ibd [3k?\]: I like w so far
adsdada: pushing once at m12
adsdada: and extending n9
adsdada: and than go for bottom side
BGATeach [-\]: So many ways to try. Black might play G9 hoping for some extra stones in the centre:
]
(;W[mk]C[BGATeach [-\]: OK White decides the middle is most important.
BGATeach [-\]: Now perhaps Black can invade with attacking options.
]
(;B[lh]C[BGATeach [-\]: Hes playing the solid move again
ctdogpdf: feels like theyve been fighting the whole game
BGATeach [-\]: Kind of shadow fighting. Every time there is a cut they just aim at it
ibd [3k?\]: w q3 soon?
adsdada: now or never
adsdada: :D
adsdada: but rather q2
ctdogpdf: cant w still attack the black ?
BGATeach [-\]: White can play B12, and try to get some extra points by threatening the black corner
BGATeach [-\]: Quite dangerous to attack black who almost has two eyes already
ctdogpdf: yeah

ctdogpdf: which direction ?

ctdogpdf: i mean the sequence is gote

;W[mp]
;B[lp]C[BGATeach [-\]: Black cant get to 60 points. White has 30 in the centre, so Black must either reduce top right to 25 or kill something.
marmoset [?\]: How much komi is there?
BGATeach [-\]: Reducing to 25 means cutting off either R12 or L16 from the cornr and attacking it. I dont think it can be done just y living in the corner with 5 points territory
BGATeach [-\]: But N3 at O5 looks like an obvious killing attack.
BGATeach [-\]: And he could afford to have a go at R16 or something first

BGATeach [-\]: And that has to start at B13, So black can live with half using C17

TobyM [1k?\]: Is n7 bestway to take the money
BGATeach [-\]: No, because white gets P8 in sente, just P6 then there is a decent cut at P8, P9 Q9 for later
adsdada: this is incredible complicated
adsdada: good taht b had some time left to figure this out
BGATeach [-\]: Yes, especially since the F17 group is still not quite alive so Blacks R16 invasion options are a bit compromised
