;B[ca]CR[ca]C[Battousai [?\]: not as complicated as it can easily get .  this is sort of a compramise both get influence which work with their opening moves
]
;W[oc]CR[oc]C[Battousai [?\]: ever the fighter Hu decides to immediately approach the 3-4. if white plays elsewhere such as approaching the 4-4 stone and black gets sente to enclose this corner then white might have to deal with a rather large moyo
]
;B[md]CR[md]C[Battousai [?\]: naturally black pincers tightly... has influence he can develop from the fight

]
;W[lq]CR[lq]C[white apparently agrees that o3 would be better and decides to take advantage of blacks high stones by attacking immediatley]
;B[oj]CR[oj]C[Battousai [?\]: nice move, cant always be responding to white, in this case m3 or you will be playing his game and not yours, this is something amatuers tend to forget

;B[mo]CR[mo]C[Battousai [?\]: p8 was small but needed to live
Battousai [?\]: however now black has 2 groups to attack, black should be happy with this position

]
;B[pc]CR[pc]C[Battousai [?\]: following up n16
Battousai [?\]: however blacks position on the bottom isnt exactly solid.   so its hard to say if black should have followed up here or attacked m3 first
]
;W[qq]CR[qq]C[Battousai [?\]: expected
]
;B[qp]CR[qp]C[Battousai [?\]: cant let it connect easily.  if this struggles for life m3 will probably be swallowed, blacks problems are solved
]
;W[lo]CR[lo]C[Battousai [?\]: which is why white tries to surround black instead.  force him to kill off r3 instead
Battousai [?\]: obvious, cant be expected
Battousai [?\]: err cant be surrounded i mean
Battousai [?\]: so black has no choice but to hane

Battousai [?\]: and black has sente
Battousai [?\]: or so it seems, however since white can play a move such as p5it would make the cut at n7 playable.  so why not try and cover such a weakness in sente

i admit that even i would think about killing white.   seeing this already as unquestioningly alive is beyond my reading for the moment.]
