JB: At this point you sadly inform him that the Kobayashi has been refuted. If you win, you appear to be right. If you lose, you claim to have forgotten the proper line.];W[lp];B[qq](;W[rq]C[JB: This would seem to be theoretically better for W than the alternate line. White has surrounding strength and should benefit most from a slow buildup. Black, OTOH, wants a quick fight - which is likely to evolve from a crosscut.];B[pq];W[ro](;B[on]C[JB: I don't know the Kobayashi well enogh to say that this is bad, but it plays into white's hands. See variations.];W[pm];B[mo]C[JB: This is just too passive. It can't be best];W[lo];B[mn];W[gq]C[I'm not unhappy with this result for B. His LR group is stable and he still has the opportunity to expand his side. If W takes the top instead, there is a big gap between D4 and M4.
JB: Seems like an overplay to me.](;B[cn];W[cp](;B[en]C[JB: Doubling down. See variations.];W[go]C[JB: This seems ideal for white. He gets a lot for his two stones, and you get so little for yours.]TR[mn][mo][lo][lp](;B[jc]C[This is a great example of the principle "urgent moves before big moves". K17 is worth a lot of points, but now the game is all about W's attack on C7.];W[dm](;B[dn]C[This now seems way to heavy and confident about pulling the group out. I'm not sure what the best alternative is, though - it didn't occur to us that this was bad in review.];W[ck]C[W commented in review that he didn't like this move, but it seems plausible to me - good use of the forcing stone.];B[el];W[cm](;B[bm]C[My idea was to provoke B8 and remove any requirement to connect around E7, but that didn't work.];W[bo]C[Now W actually manages to let B live independently with B7 without threatening any real attack on the C7 group.
JB: Play B6 and thank him. You WANT to connect, right?](;B[bl];W[dk];B[bk];W[bn]C[JB: Alas, your game is now over. ];B[ci];W[di](;B[cj]C[JB: Either extend or hane, and devil take the hindmost.];W[dj];B[em]C[This is a pretty miserable move. It's so heavy. Alternative ideas: play C12 and let W have D6 if ihe wants; reduce lightly around L7. During the review, I looked into G6, but it's not promising.

The idea of E7 was that if I had no attack on D9, my entire way of playing up to here was ridiculous.];W[ch];B[bh];W[bg](;B[bi];W[dg];B[aj];W[hl];B[eh];W[dh];B[fk]C[JB: I must say that I admire your persistence. ];W[fj];B[hk]C[This doesn't really work very well.];W[gk];B[gl];W[gj];B[hm];W[il];B[gm];W[im];B[ho](;W[in]C[Having read out the cut in the game and in the review and again now, I'm still not sure whether or not W can cut at h6.];B[hn];W[hp];B[io];W[kn];B[ep];W[eq];B[fp];W[fq](;B[jo](;W[kq];B[jn];W[km];B[jm];W[jl];B[kl];W[ij];B[kk];W[jj];B[iq];W[gp]C[This is the one move I'm not sure about.];B[lm]C[Now B has some tiny hope...];W[ip];B[ko];W[ln];B[jq];W[jp];B[kp];W[lq];B[kr];W[lr];B[jr];W[nq];B[nr]C[This is horrible.
