;B[cd]C[With this move, Black chooses to isolate the d10 stone and abandon f17 for the moment.]
(;W[cc]
;B[ce]
;W[dc]
;B[eg]
;W[fg]C[White is leaving a weakness at D15, but aiming at a weaknes at C13. If Black cuts straight away....]
(;B[ei]C[I dont like this move. Black cannot attack d10 effectively when the weakness at c13 is left behind. Simplest here is j17, I prefer c12.]
;W[gf]C[This move invites Black to try to cut at d15, presumably AK has a plan for that. However it certainly ignores the fate of d10. Most of the rest of the game is about Blacks attack on d10.]
;B[di]C[Now Black has spet two moves preventing c13, and it is still a weakness. Far better have playd c12 before.

For this move I prefer D7 or thereabous.]
;W[cj]C[Andrew Kay loves to attack, even if he is attacking strong stones. This move invites Black to play C7.]
;B[ci]C[Finally preventsC13. But why not B11 which does that while undermiming White on the side?]
;W[cn]
;B[co]
;W[dn]
;B[fp]
;W[jc]C[This sequence is a big success for White - he has found time to settle the left side and to get the big move at the top.]
;B[cl]C[Black has to justify his previous play by finding an attack.]
;W[dl]
;B[bl]
(;W[bj]C[Andrew Kay always likes to defend aggressively. He has still not given up attacking the C15 group despite Whites having added 3 stones (C11,12,13)]
;B[bn]
;W[bh]
;B[bi]
;W[ai]
;B[bg]C[Now Black is very nearly alive.]
;W[gi]C[Brinkmanship. The white stones on the left are almost dead
]
;B[fj]
;W[fl]
;B[gj]
;W[hj]
;B[gl]
;W[gm]
(;B[hk]C[Wrong direction. This makes Black unnecesarily strong, and pushes White from behind almost forcing him to surround the 120 point territory which eventually won the game. Black should cut at h11]
;W[ij]
;B[ik]
;W[jj]
;B[jk]
;W[kj]
;B[fn]C[If this does not kill White cleanly the result is very good for white. if white is alive, then Black needs a lot at the bottom and also an invasion of the top

;B[ej]

;B[jm]
;W[ek]
(;B[en]C[Black is trying to kill. If he had read a bit more carefully, the mayhem which followed could have been much more one sided.]
;W[gk]
;B[kk]C[This is obviously meant to kill White, 
]
;W[ch]
;B[dh]
;W[bc]C[I guess Black failed to spot this move, and thought he was completely alive
]
(;B[ah]C[As so often, the move after the mistake is the big mistake. This fatuous throw in gives White something to do.]

;W[ae]
;B[lj]C[so, its a ko. ]
;W[li]C[Although the ko is for over 100 points, these mutual influence points in the centre are more important.]
;B[ad]
;W[fh]
;B[ak]
;W[ae]
;B[mi]
;W[lh]C[Notice that white cannot win the ko with just one move.]
;B[ad]
;W[de]
;B[bk]C[Andrew Symonds has noticed that White could play D9 as a ko threat, This move stops that one, but allows White 4 extra ko threats. 
A bad mistake. J8 would be much better]

;W[am]
;B[bm]

;B[mg]
;W[mj]
;B[lk]
;W[nj]C[For now, the fight in the centre is bigger than the ko.]
;B[mf]
;W[pj]C[Now the game gets clearer. If Black can win the ko and live with N14 he wins. If White can win the ko he still needs to live with attitude with the n10 stones. If Black kills n10 he wins regardless.]
;B[ph]
;W[nl]C[This looks very slow. Notice that the cut at k6 is only useful if White wins the ko.
]
;B[ad]C[Too small. Black should be securing the N14 group. R14 seems to be a clear way to do that.]
;W[bo]
;B[bp]C[Perhaps Blaxk was hoping for this exchange so that he is sure c3 cant live in the corner.]
;W[ae]C[TheThe [3k\]: ok, at least c3 will not work for sure npw
TheThe [3k\]: *now
]
;B[lf]
;W[pf]C[Finally White can see a clear way to win.]

]
;B[hl]C[Since white still needed two moves to win the ko, I prefer to play this stone t q13, aiming to find ko threats to kill the n10 group. Black has lots of points at the bottom. and can win by making a profit on the right side.]

wade [5d\]: making ultimate empty tringle kill

liusasori [4d\]: o16 n17 and b almost alive directly
