;B[do]BL[44.253]
;W[cm]WL[51.065]C[Hmm. I don't know what move to play. I guess I'll tenuki and play P4.]
;B[op]BL[37.198]
;W[oq]WL[46.801]
;B[nq]BL[30.103]
;W[pq]WL[45.882]C[Hmm. Now it might work out if I had stones around E3. So I'll play C3. If he cuts at C4, I can do D4, and will probably get E3.
(**Post-game thinking: I had limited thought about the joseki. There are several choices when I play C3, and I only considered one of them.**)]

;B[cp]BL[10.548]
;W[er]WL[40.712]C[OK, D5 stone is not that weak, so I'll ocntinue bottom right.
I could play O4... But N4 might be OK, because J3 wouldn't be bad, with a followup maybe at F3.]

;W[qn]WL[35.994]
;B[iq]BL[10]OB[2]
;W[fp]WL[30.804]C[OK, D5 getting weaker. I'll attach to get some help, but then play J5 to help bottom.]
;B[fo]BL[10]OB[2]
;W[go]WL[27.501]
;B[fn]BL[10]OB[2]C[OK, when he does H4, I play J5. He can J5, though, so it's not idea. I must've made a mistake.]
;W[dn]WL[16.311]C[Hmm, he ignored, I 'll cut.
(**Post-game thinking: Maybe E4 is better. It's not huge to help J3, although desirable. It's urgent to help F6, though.**)]

;W[eo]WL[4.668]C[OK, he cut me. Not much time to think, but not the end of the world. I can see if I can get anything from it.]
;B[en]BL[10]OB[2]
;W[ep]WL[2.938]C[Hmm, no time to think. Just a couple of seconds. OK, Q5 is probably a move he'll respond to, so I'll do that to buy time.]
;B[po]BL[10]OB[2]
;W[qo]WL[10]OW[3]C[Hmm, hard to sac D5.. Any way I can live? I guess I'll try.
(**Post-game thinking: Maybe I should still sac them.**)]

;B[ar]BL[10]OB[2]
;W[co]WL[10]OW[3]C[Hmm, not quite enough eyespace: B5 A7 A4, B3 is sente for capturing two stones...
Still, no time, so I'll defend.]
;B[bo]BL[10]OB[2]
;W[bq]WL[10]OW[3]C[Hmm, so a few more seconds of thinking, and maybe I can play D5, and exploit C8 cut somehow via ko? Get something from ko threat? I dunno.
Gotta play!]
;B[do]BL[10]OB[2]
;W[aq]WL[10]OW[3]C[Woah, he captured those. Ah well, another ko threat.]
;B[cl]BL[10]OB[2]
;W[bk]WL[10]OW[3]C[OK.. Sucks to lose bottom left corner, but maybe make him walk along 2nd line. I have potential in bottom, so maybe I can use that and left side to make up for this..?]

;B[hi]BL[10]OB[2]

I guess I take what I can get with K8.]

;W[im]WL[10]OW[3]C[Hmm, tricky. Ok, I'll just take these stones at L6.]
;B[jn]BL[10]OB[2]
;W[in]WL[10]OW[3]C[Wait a sec. What if he does H5, again? Oh no... Better start ko again.]
;B[il]BL[10]OB[2]
;W[jo]WL[10]OW[3]C[Hmm, this works, cause I can either capture H5, or cut at one of his two cutting points.]

I've made two big strikes. 3 strikes and I'm out. I say I have about 20% chance of winning here.
Let's go for it.]
;B[pj]BL[10]OB[2]
;W[jd]WL[10]OW[2]C[OK.
Switch to super-duper aggressive mode. I've got to benefit from central power fast in order to make up for those two dead groups.]

;B[ql]BL[10]OB[2]C[OK, I've got lots of points... Maybe I have a 50% chance, now.]
;W[oh]WL[10]OW[2]C[OK, this is it. I've got to kill this stone. If I kill it, I think I win.

;W[nn]WL[10]OW[2]C[Ok, just O7. Wait a sec. He can cut at N5. Then I have two cutting points at M4 and M6.
I've gotta protect it.
(**Post-game thinking: I was wrong, of course. He has a shortage of liberties from earlier. If I block him off, I have a lot more points. *See variation* **)]

as is shown in the pro games I linked? The only thing I feel I've learned is that the exchange is bad in my game, but there's not really an explanation of why.
here is to make black over-concentrated to attack. But when I first saw this pro game, I didn't think that white could really attack black very much.
if he can't attack black?"
