;B[jb]C[BGATeach [-\]: this clone of the British championship game is now active
BGATeach [-\]: Sorry folks, I got locked out somehow.
BGATeach [-\]: looks like black just stole some free points in the lower left. Now he is trying to make it a game of territory
BGATeach [-\]: At the bottom, there are enormous points at R7 and L4. perhaps AS thinks they are miai so he can gret on with taking the top, which incidentally strengthens his G14 group
fortytwo [?\]: There seem to be two games owned by BGA teach?
fortytwo [?\]: the other one has more observers
BGATeach [-\]: Yes. One of them has died on my computer, I cant get into it so this is the active one
BGATeach [-\]: If White is determined to mess about here, he can make two groups:
]
(;W[hd]C[BGATeach [-\]: Here is the game. White is trying to get sente
BGATeach [-\]: Looks very hairy: What if black resists:
]
(;B[hb]C[BGATeach [-\]: Hes asking the question. This has the look of a white blunder
BGATeach [-\]: losing J18 is very painful for White. Suddenly the top side looks like solid black territory
]
;W[he]C[BGATeach [-\]: What's the little fellow up to???
]
;B[hc]
;W[ie]C[timhunt [?\]: Amazing net if it works
timhunt [?\]: Looks too thin
timhunt [?\]: I mean, attempt to net E14 group?
BGATeach [-\]: Black can cut the group off, but doesnt have to.
]
(;B[hg]
;W[gc]C[BGATeach [-\]: AS is keeping calm
]
;B[jd]
;W[gd]
;B[jf]C[BGATeach [-\]: Now White can make eyes at G19. This is a big loss compared to J17
BGATeach [-\]: And White can make trouble at J13 before living.

;W[ih]C[BGATeach [-\]: This is not impressive for Andrew
BGATeach [-\]: better now find a way to sacrifice the F15 stones and build the top right corner.
BGATeach [-\]: K14 was far too thin to work
BGATeach [-\]: Black can also try to find a ladder breaker around Q7, but even if that worked he canot kill F18, and he would have to give up the invading moves at R7 and R4
BGATeach [-\]: How about this:
]
(;B[kh]C[BGATeach [-\]: He has found a similar idea
timhunt [?\]: K11
]
;W[ii]C[timhunt [?\]: No
BGATeach [-\]: K11 didnt work to K12
timhunt [?\]: Yes. Thanks.
BGATeach [-\]: now Black can try G10 and aim to get 7 liberties or escape
BGATeach [-\]: or he can e.g. L10 and invite white to capture something, then play R7 and claim the whole upper right area
BGATeach [-\]: Probably cleanest was to play L12 at J11
BGATeach [-\]: Lets look at the capturing race:
timhunt [?\]: Black is now in overtime
timhunt [?\]: (10 stones in 10 mins)

(;B[gb]C[BGATeach [-\]: Black came from the wrong side. Now no ko
timhunt [?\]: Black is left very thin when white takes
BGATeach [-\]: Black could try starting at Q5 to improve his ko threat, but there is no ko now
BGATeach [-\]: The trick was to get F19 to be atari so he could avoid needing the extra move at J17

]
;B[kj]C[BGATeach [-\]: AS has stopped believing he can win
timhunt [?\]: I make it W just short of 60 points in the big territory.
BGATeach [-\]: Yup, plus 25 lower right plus komi makes nearly 100.
BGATeach [-\]: Black has at most 25 outside the top right, so he needs to join up the whole 10 line
BGATeach [-\]: at the same time as holding white to 25 lower right
BGATeach [-\]: IMO white R7 is an easy win, or R17 is a big win
]
;W[pd]C[BGATeach [-\]: Not to mention M11
timhunt [?\]: I wonder how confident Danielis in his counting?
timhunt [?\]: Well, that is an answer. He is confident to fight.
timhunt [?\]: (With AS in overtime(
timhunt [?\]: )
BGATeach [-\]: I guess he has seen a ladder starting N12 and M14, and he wants an easy quick win
BGATeach [-\]: As Black I might try N13 here, to invite white to try living in the corner and screwup
]
;B[qc]
;W[mh]C[BGATeach [-\]: This way White can play lightly at Q13
BGATeach [-\]: but actually hes going for the kill
BGATeach [-\]: I guess his reading is like this:
]
(;B[mj]C[BGATeach [-\]: 127 is pretty well forced
]
;W[nj]
;B[nk]C[BGATeach [-\]: See how much better this would look if G7 were still open - White would need to be able to run away at k7
BGATeach [-\]: q10 is good for white here, no need to fight stiffly
laoky [3d?\]: o11 sente?
BGATeach [-\]: yes o11 is sente
BGATeach [-\]: 10 stones in 10 seems quite slow
BGATeach [-\]: The game had some sort of logic to it until White H4, which was greedy. Then both sides kept refusung generous offers.
BGATeach [-\]: after that, Black K18 was a normal forcing move requiring H18. Daniel refused and then both sides' reading let them down
