;B[ce]C[I was surprised by this tenuki as I thought black would try to develop the sanrensei immeditaly and lure me into a moyo game where i would have to create a weak group somewhere after invading black influence.
But nowadays AI show various approaches including this type of tenuki where you develop some influence and then play fast all around the board.]
;W[ed]
;B[cq]C[This move surprised me also. I was happy with it as with 3 stones at the top I will be able to take the initiative. My only concern now is to take sente and there is a very easy variation for that, just extend]
;W[cp]
;B[dq]
;W[ep]
;B[fr]
;W[qc]C[I was not sure which of this move or C12 was the most urgent. C12 is super important as it pincers black AND help the white group at the bottom but I also want to punish the fact that black didn't develop his sanrensei. I thought I might be able to end up in sente there and decided to dive in the 3-3]
;B[pc]C[I was so surprised by this block, as it doesn't seem to work well with Q10 but AI seems to agree!I guess when black doesn't develop the sanrensei then the whole role of each stone has to be reviewed. Overall I don't think the black stones are working well together at this point.]
;W[qd]
;B[pe]
;W[rf]C[it seems AI prefers Q18. I was very happy to play s14 as it completely undermines Q10 stone]
;B[lc]
;W[ch]C[Now i am super-happy to play this pincer. If I can get a natural development leading me to play K17 I will be ahead I think and I have no weak group for now, whcih with Matei is important!]
;B[cj]
;W[cl]
;B[ej]C[Probabaly a mistake. White group at the bottom is not so weak so getting the black stone out at E15 is very big.]
;W[df]C[Now white is ahead on territory. There is some aji left in C15 but not so easy to activate particularly with the two floating stones at E10. I would probabaly spend a move securing them now at E8 or play the very big move at G3 to help them indirectly]
(;B[bn]C[this moves seems a bit greedy. It will damage the corner for sure and the white group won't be easily attacked.]

;W[fq]
;B[er]C[This is too cautious, black mut go out at g3as being surrounded is really too painful]
;W[bm]C[probabaly playing h3 first ws big. G2 seems not needed and lead to unnecessary complications for w who has a very good flow up to this point. This B7 move still works well]
;B[cn]
;W[an]C[I can jump at E8 first instead of this]
;B[gq]

;W[hq]
;B[gr]
;W[hn]
;B[fn]C[At this stage w will make a huge blunder. Attacking these b stones is key and w doesn't have time to look around as the D4 group is now surrounded so D9 or E7 are key points. I was afraid that b might just sacrifice and develop the right but this is big but not urgent for now ]
;W[jo]
;B[el]C[B immediatly sees a chance here and split white. I don't have a strong move to harm the two black stones so now i suddenly have two groups to look after... Worse news : the w groups seems dead! AI showed me a nice sequence to live starting with peep at D9 but during the game it didn't seem that promising]

;B[dl]C[sequence is a disaster and w seems dead. But I still saw the cut sequence at F8 combined with the G6 and F7 sente move so tried to exploit this aji]
;W[ek]
;B[fk]
;W[di]
;B[bh]C[May be the loosing move for b ? Suddenly w can play the tesuji at A10 and threatens to capture the whole b group or to capture the three cutting stones]
;W[aj]
(;B[cg]
;W[ak]
;B[dg]C[final result is good for w. Black has slightly damaged the top left but in fact his group is also weak and he has a weak group in the center to take carea bout too. This time b is split in two again.]
;W[ei]
;B[gl]
;W[jq]
;B[nq]C[May be a bit greedy. A move around J17 or even in the center is priority for now]
;W[ir]
;B[hr]
;W[io]
;B[hq]
;W[hk]C[this is painful for b as his hsape is not great. b can live inside but doesn't want to play the atari at C7 which will suddenly remove all damezumari on E11 stones and the atari at A11 which might be needed for life at the top]

;B[lq]C[So here I could feel the w group had time before being under complete pressure. I also misread completely that I could connect with G6]
(;W[jc]C[this is a huge move as it increases white area and threaten the black stones from far away. May be a bit greedy though and a more secure move at H16 was in order.]
;B[nl]C[b expands his bottom right looking to kill w. If black is dead at the top left then the bottom right won't be enouhg though so b needs to kill.]
;W[qg]C[w still under his misread illusion tenuki again grabbing the last big points and helping the white group from far away (this stone will proove to be key to save the white group)]
;B[hc]C[Black tries to complicate matter to use aji of C16 stones and F14 and M17 at the same time. I calculated that capturing cleanly F14 should be enough to win if I don't die in the center]
