C[This game will lurch around like crazy in the endgame. It's enough to make you dizzy.]

BL[2683.3]CR[pl]
C[Black is off to a good start with a squeeze that works well with the upper right corner.]
;W[oq]WL[2664.3]CR[oq]
C[Yes, White wants the outside if possible];B[or]BL[2668.5]CR[or];W[qq]WL[2658.8]
LB[op:A]CR[qq]
C[This is a trick! The josek calls for White to play A.];B[qr]BL[2662.5]
LB[op:A][pp:C][nq:B]CR[qr]
C[Black has fallen for the trick and groveled low.

The correct thing would be to play A, White B, Black C.  White's position would then be in smithereens. Black could be equally happy if White allowed Black to capture with B.]
;W[pp]WL[2653.7]CR[pp];B[pr]BL[2659.1]CR[pr];W[nq]WL[2649.0]CR[nq]
C[
Correct. White wants the outside to break apart the value of Black's three outside stones.]
;B[qp]BL[2654.3]CR[qp];W[qo]WL[2647.7]CR[qo];B[rp]BL[2651.8]CR[rp];W[ro]
WL[2646.6]CR[ro];B[rq]BL[2649.3]CR[rq]
C[Black gets the corner, but it is a dead end. The outside Black stones weep for the loss of friendship with their comrades.]
;W[pj]WL[2641.5]CR[pj]
C[Good. The only way White can take advantage of this thick wall is to attack. If White lets the chance go by, White cannot use his stones effectively.]
;B[nl]BL[2646.0]LB[jc:B][qg:C][cj:A]CR[nl]
C[No. Black should run if he has a plan to counterattack with profit. I don't see it.

Black should take sente to a big point. A-C are all ok. Let White have a stone in a small way and seek compensation elsewhere.]
;W[qg]WL[2634.9]CR[qg]
C[White gets a base on one side, gets profits, and weakens Black's corner. Black should be unhappy.]
;B[nc]BL[2641.3]CR[nc];W[qk]WL[2631.3]LB[cj:B][cn:A][fq:C]CR[qk]
C[
Pheew! Stinky move.  If White is going to play in this area, White must attach. But this move is not worth much. White has a base and Black can't get one. What more does White want?

White should develop on the outside and wait.  A & B are good. C is from the wrong direction, as White is undercut on the bottom edge and wants to develop from the top left.]
;B[ql]BL[2636.4]LB[df:B][cj:A]CR[ql]
C[Better to take sente and let White play another move here. Imagine Black A, White at circle instead of Black, Black at B.  Then White has a lot of stones on the right but not doing all that much.]
;W[rl]WL[2624.2]CR[rl];B[rm]BL[2634.1]CR[rm];W[rk]WL[2622.3]CR[rk];B[qn]
BL[2633.4]CR[qn];W[pn]WL[2616.7]CR[pn];B[oj]BL[2625.1]CR[oj]
C[Since White is alive on the right and can join from the bottom, Black cannot attack White. And Black's stones are outside of White's sector line, so Black does not need defense right now. Take sente.]
;W[oi]WL[2612.9]CR[oi];B[nj]BL[2623.2]CR[nj];W[cn]WL[2600.9]LB[pk:A]CR[cn]
C[A good point to take, but better to first play A to ruin Black's shape. It will be sente because Black has already been spending his time here, demonstrating his commitment.]
;B[gq]BL[2616.6]LB[no:B][lq:A]CR[gq]
C[Even at my strength I don't like the large-knight's move from handicap corner. It's invadable. Black is better playing small knight's for local profit, and then playing to A later to attack and build a moyo. If White ignores A, Black can then play B.  It will be OK to force White to connect on the right making no profit.]
;W[dk]WL[2596.7]CR[dk];B[mo]BL[2611.4]LB[no:B][lq:A]CR[mo]
C[Misses the shape point and not yet profitable. A is much better. THe shape point is B.]
;W[nn]WL[2568.5]LB[ic:B][lc:A][kq:C]CR[nn]
C[No need. Take sente to A or B. Gets White a double wing. Black has no attack on White yet.  if White is to play locally,  C is probably more useful in keeping Black from making profit and working to threaten the lower right corner. If White invades the corner, Black could lose his base.]
;B[mn]BL[2609.0]CR[mn];W[nm]WL[2563.8]CR[nm];B[mm]BL[2607.1]CR[mm];W[ml]
WL[2562.9]CR[ml]
C[At least White has played consistently. once started, White must continue with the cut.]
;B[ol]BL[2603.8]LB[ll:A]CR[ol]
C[OK, But it would be better to play A to make White commit to saving the stone. If White trades and plays circle instead, Black can be happy to make central thickness and get sente, having lost any problems of defense in the area. White may get a couple of stones, but so what?]
;W[mk]WL[2560.0]LB[ll:A]TR[nj:oj][nl:ql]CR[mk]
C[Bad direction. A helps threaten Black's three stones. White wants to attack the marked group, so threatening the OTHER stones will help do that. Playing this way helps provoke Black into defending his marked group.]
;B[ni]BL[2600.8]CR[ni]
C[See.];W[oh]WL[2558.3]CR[oh];B[lj]BL[2597.8]CR[lj]
C[Now Black is turning the tables and getting a better attack on White.

Contact the stronger stones to attack the weaker. White didn't, Black did, Black is now getting the better of this fight.]
;W[kl]WL[2551.5]CR[kl];B[lq]BL[2595.4]TR[no]CR[lq]
C[OK but Black might as well play triangle first.];W[lp]WL[2537.4]CR[lp]
C[This piecemeal will harm White more than Black.];B[mp]BL[2593.0]CR[mp]
;W[mq]WL[2536.4]CR[mq];B[kp]BL[2590.9]CR[kp];W[lo]WL[2535.2]CR[lo]
(;B[ko]BL[2583.0]TR[kn]CR[ko]
C[Too direct. Better is to play at A.];W[ln]WL[2534.2]CR[ln];B[lm]BL[2582.3]
CR[lm];W[kn]WL[2532.3]CR[kn];B[km]BL[2581.6]LB[ll:A]CR[km]
C[Black should play A to commit White here. Pushing as Black does damages the bottom.]
;W[jn]WL[2531.5]CR[jn];B[jm]BL[2580.4]CR[jm]
C[Black still doesn't have the two stones captured and White can make safe.]
;W[kq]WL[2525.6]CR[kq]
C[White is safe and has profit. Black will have to get safe in gote.];B[jq]
BL[2575.1]CR[jq]
C[Useless. White is safe already. A few black stones in the area have NO strategic significance.]
;W[lr]WL[2515.4]CR[lr];B[in]BL[2571.4]CR[in]
C[just silly.];W[io]WL[2507.7]CR[io]
C[Black is getting deeper and deeper into trouble];B[im]BL[2566.3]CR[im]
;W[ho]WL[2487.4]CR[ho]
C[White is attacking Black's corner as well as the Black group above. Better to take sente, however, since the profitability of this is unclear and White is already completely safe.]
;B[ij]BL[2564.7]CR[ij]
C[Fine. Black is safe in gote.];W[fq]WL[2484.1]CR[fq]
C[OK];B[fp]BL[2561.7]CR[fp];W[gp]WL[2482.2]LB[eq:A]CR[gp]
C[NO. Black can capture the stone and be alive. White would have to play at A to try to attack the whole corner and take away its profit in sente.]
;B[eq]BL[2560.1]CR[eq];W[hq]WL[2479.8]CR[hq]
C[No value. Sente is better.];B[gr]BL[2558.8]CR[gr]

;W[gc]WL[2364.1]CR[gc]
C[Finally somebody takes sente. Trying to escape and failing only helped Black. White got in no useful stones.]
;B[df]BL[2530.1]LB[cf:A]CR[df]
C[Unnatural invasion point. Want dual threat. A threatens to slide and run.]
;W[ch]WL[2355.3]CR[ch];B[ff]BL[2526.1]CR[ff];W[fh]WL[2337.3]LB[jc:B][cd:A]
CR[fh]
C[No. No value to this move. A and B are better.];B[ed]BL[2514.2]LB[cc:C][ic:B][hf:A]
CR[ed]
C[NO. just helps White.  Run out to A. Then you can play B or invade at C.]
;W[ec]WL[2333.3]CR[ec];B[fd]BL[2510.2]CR[fd];W[fc]WL[2332.2]CR[fc];B[jd]
BL[2505.9]LB[jc:A]TR[jf:lg]CR[jd]
C[Black has lost the invasion opportunity in the corner. And this high move does not take territory. A is better. There is no moyo value in the marked area since White has multiple ways in.]
;W[he]WL[2324.4]CR[he]
C[Like this way in that attacks as well.];B[gg]BL[2503.6]CR[gg];W[gh]WL[2323.4]
LB[lc:D][rd:B][ig:A][bp:C]CR[gh]
C[There is no value in this direction for White. White might well prefer to attack with A and force Black to play here. But it is too soon to tell. So White should take sente. B & C are proftiable and cheap. D is fun, but does White need to invade? 

Black has something like 19x3.  White has something like 20x3 + komi. If White just plays B in and C in sente White is doing quite well enough.]
;B[hg]BL[2501.3]LB[if:A]CR[hg]
C[Slow and ponderous. A would seal off this area from this side and be safe.]
;W[hh]WL[2317.9]TR[hj:jj]CR[hh]
C[White keeps adding stones in a direction of no use.  They face the strong black marked stones below. So don't do this.]
;B[jg]BL[2493.7]CR[jg];W[je]WL[2309.4]TR[jb][mg]CR[je]
C[Why is White attacking from above. The profit is nearer the edge.  Triangles are good places to go to deal with Black potential, but I still prefer my corner slides.]
;B[kd]BL[2491.2]CR[kd];W[id]WL[2299.6]CR[id];B[if]BL[2488.0]CR[if];W[ke]
WL[2295.4]CR[ke]
C[NO. risk risk risk. Just connect.];B[ld]BL[2482.8]CR[ld]
C[No. cut white apart. you are safe and you will get to secure the upper edge and MAYBE get to capture the stones.]
;W[le]WL[2267.7]TR[oh:ph]CR[le]
C[White continues to take risks, since White cannot guarantee connecting over to triangle safely if White gets cut.]
;B[ie]BL[2478.2]CR[ie]
C[Tardy. But good.];W[md]WL[2264.7]CR[md];B[ic]BL[2473.1]CR[ic];W[hd]WL[2263.1]
CR[hd];B[mc]BL[2472.1]LB[re:D][nf:A][bn:C][bo:B]CR[mc]
C[Yes, Black gets his edge profits. White now has a liability. If White is successful, White gets no additional points and loses sente. If White is unsuccessful, White dies.  Really bad pair of results for White. 

If we assume White saves himself and Black gets sente, then we get something like White A, Black B, White C, Black D.  Now Black has grown and the score looks like Black 21x3, White 21 or 22X3 plus komi. The game has become close, where previously White had an easy lead.]
;W[ne]WL[2237.8]CR[ne]
C[Black could capture White.];B[mf]BL[2457.0]CR[mf]
C[yes];W[me]WL[2230.7]CR[me];B[nh]BL[2455.4]LB[of:A]CR[nh]
C[NO. Black at A would insure White could not escape.];W[ih]WL[2221.8]CR[ih]
C[This peep is not sente. Black could engulf the White stones and count on winning a race to capture.]
;B[ig]BL[2452.0]CR[ig]
C[But I did expect Black to defend here.];W[jh]WL[2210.2]CR[jh]
C[Again White crawls in, risking the race to capture.];B[kh]BL[2450.0]CR[kh]
C[And again Black just takes it.];W[kg]WL[2207.5]CR[kg]
C[White is trying too hard. Better to have connected to safety and let Black defend this cut in gote.]
;B[kf]BL[2448.8]LB[of:A]CR[kf]
C[Once again Black at A would be better.];W[of]WL[2186.8]CR[of]
C[Finally!];B[bp]BL[2442.3]CR[bp]
C[Not bad. This has good followups into Whites area.];W[qc]WL[2146.4]CR[qc]
C[White can seek ko in this corner, but I'm betting Black will let White live without it.]

;W[ma]WL[2082.9]CR[ma]
C[Thank you thank you thank you thank you. Black must say these words as White continues to help Black make the plays he will eventually need, at no cost.]
;B[na]BL[2413.1]CR[na];W[pa]WL[2058.6]CR[pa]
C[There is no ko here unless Black wants one. And it would be so long a ko that White would forget to play it eventually.]
;B[rf]BL[2408.1]CR[rf]

CR[rg];B[qf]BL[2406.6]CR[qf];W[sc]WL[2045.9]CR[sc]
C[This is White trying for a ko that White cannot win. Black would have to ignore so many threats in a row before White had a chance.]
;B[sd]BL[2404.9]CR[sd];W[pf]WL[2043.3]CR[pf];B[sf]BL[2403.0]LB[sa:A]CR[sf]
C[Don't be greedy Black. Just make sure you don't end up with trouble. Play A.]
;W[sg]WL[2037.8]LB[pe:A]CR[sg]
C[Bad place to play. Should be at A to keep Black's eyespace down.];B[pe]
BL[2401.1]LB[oe:A][nf:B][lg:C]CR[pe]
C[Black can live now by capture or 2 eyes. If White wants to try to sucker Black, White should block the 2 eyes. Black may see the atari at A, White defends at B. Black captures and White extends with C. Sucker now cut off.]

C[BAD!  Black now risks ko in this area. Black should have played A and gone after the other stones.]
;W[ha]WL[2000.8]CR[ha]
C[Now it is ko time.];B[sc]BL[2374.6]CR[sc]
C[NO! Black must capture the ko. Even if it didn't work out, Black's capture would at least force White to use up a ko threat.]
;W[nd]WL[1990.2]CR[nd]
C[Ko is joined.  Thank you thank you thank you.  White must say this to Black.]
;B[la]BL[2373.0]CR[la];W[lg]WL[1974.4]LB[cq:A]TR[ed:fd][ie:ig][df][ff][gg:hg][jg]
CR[lg]
C[This is nice, but we can be certain Black will win the ko. It's too big to lose. So if Black takes the ko, can White kill Black's marked stones?  Probably, but there is uncertainty.  So I might prefer A as a ko threat.]
;B[kc]BL[2351.5]CR[kc]
C[Yes,  White has too many threats. Black's group will have to take its chances.]

C[BAD SHAPE. No threat and no value to this move. A was better. Threat and shape.]
;W[bg]WL[1947.9]LB[cg:A]CR[bg]
C[Sort of ok, but better at A. Black might get a ko for shape in this area. If Black lives, White's ko threat was minimal before and White will be losing significantly.]

CR[dg]
C[No. Black can still aim for a ko with Black  A, White B,  Black C. White should play C (the original move I suggested to be a better move for White.]

C[Mildly interesting but forces White to kill Black.];W[eg]WL[1891.7]CR[eg]
;B[ei]BL[2292.7]LB[fg:A]CR[ei]
C[So White can connect at A. Black is dead and Black can struggle with his two stones. The game keeps lurching from potential winner to potential winner. ]
