(;B[eh]C[In the actual game, black jumps out.]
(;W[dj]C[The diagonal's interesting.]

;B[bq]
;W[fn]C[White protects on both sides.]
(;B[kq]C[Black asks a question first. This is kind of a tit-for-tat type of thing where black didn't finish the joseki.]
;W[er]
;B[bn]
;W[cn]
;B[ao]
;W[co]TR[bn]TR[cn]TR[ao]C[Then black makes these exchanges.]
;B[dr]
;W[jr]C[Then white plays here...]
;B[bm]C[... and black extends.
I think black's invasion, while not wrong, didn't give him a lot to hope for. He also ended in gote here.]
;W[cg]SQ[cd]SQ[dd]SQ[ed]TR[mp]TR[kq]TR[nq]TR[oq]TR[pq]TR[lr]C[White takes this.
So for the most part, both players settled this situation. White's saying the O3 group is still dead, and now she's attacking the D16 group.]
(;B[he]C[Black plays a large knight's move. The flow of the game changes here.]
;W[ge]C[This type of cut in most amateur games would leave to the death of a group.]
;B[bc]

;W[fc]
;B[hg]TR[bc]TR[ec]TR[cd]TR[dd]TR[ed]TR[be]C[Black's saying he's gonna give up the D16 stones.]
(;W[jj]C[White doesn't fully cut.]
(;B[kh]C[Eventually, black is going to get this move anyways.]
;W[jc]

So for example, black had some really nice moves in the center, but he never followed up on the stuff on the left side.
So now white could potentially capture the D16 stones; she has access to the top side; she has some good endgame in the bottom right; and she even reduced the center in a very good way.]
(;W[gg]C[In the game, white attaches.]
(;B[ad]C[Black decides to start the ko because there's no way to escape now.]
;W[bd]C[Black can't necessarily keep all the things.]
(;B[cf]C[Immediately, black plays this move that doesn't yield much...]
;W[bf]
;B[gh]C[... and then hanes. So black's started the ko but he doesn't have ko threats; that's kind of typical.]
;W[ki]C[And then white says, "because you don't have ko threats, I'm going to play some forcing moves."]
(;B[bc]
;W[eb]C[White connects...]
;B[ab]C[... black takes...]
;W[lh]SQ[bd]TR[ce]C[... and then white connects again.
This trade seems favourable for white. She was able to reduce the center. Black got some of the top left corner back, but didn't fully take all of it. He's not even fully alive there; he needs to connect at C15 to make B16 an eye. Obviously, it's almost miai in a sense.]
;B[hj]TR[of]TR[lg]TR[og]TR[lh]TR[oh]TR[ki]TR[oi]TR[jj]C[In a sense, it looks like black did get what he wanted, but I would say giving up [his attack on\] the P14 portion was probably larger.]

White has gained control of the game here, connecting the P14 group while the C17 group lived peacefully.]
;B[bk]C[Black is forced to play another move here so he doesn't have to play in the corner.]
;W[ba]C[White gets to play sente moves and comes back here.]
;B[ce]C[Black needs to connect.]
;W[gi]C[And then white clamps. This is a really nice attachment.]
;B[hh]
;W[hi]TR[gi]C[With G11, white's essentially saying, "now the game is in my control; I'm going for this very large center."]
(;B[km]
;W[jn]
;B[jm]
;W[in]C[I think any player would play this, just because white wants to make sure she solidifies the bottom territory.]
;B[ii]C[We finally come to this position where black now needs to move in.]
;W[ij]
(;B[hk]C[Some people might argue that this move probably changed the flow of the game; because of the way the game went "psychologically", if it was a human player, I could see someone playing this being, like, "this area is too big; I need to do something about it."

;B[eg]

;W[mn]TR[hj]TR[hk]TR[im]TR[jm]TR[km]TR[hn]TR[go]C[... but from my perspective, when white connects here, the cut exists. The H10 stones are in danger.]

;W[hr]
