 imp NR : hi

;W[qp]C[
 imp NR : ok:)
 imp NR : typo:)
 jansteen 3d*:  :)

;B[op]
;W[mq]C[
 jansteen 3d*:  Caspar heeft ook nog gespeeld met Yasuda
 imp NR : o5:)
]
;B[or]C[
 jansteen 3d*:  Nee, dat speelde Caspar, dus ik dacht laat ik iets anders spelen
]
;W[qm]
;B[no]
;W[kp]C[
 jansteen 3d*:  Volgende zet?
 imp NR : k3 neem ik aan. r3 beetje slap?
 imp NR : sory j3
 jansteen 3d*:  Ja, j3 speelde ik, maar da's niet goed
 imp NR : rustig g3?
 jansteen 3d*:  Nee, j3 is het goede idee
 imp NR : j4 dus
 jansteen 3d*:  ja :)
 imp NR : maar hoe te kiezen, waarom die en niet een ander
 jansteen 3d*:  Begrijp je waarom?
 imp NR : niet echt nee
 jansteen 3d*:  j3 zou in functie overlappen met p2
 imp NR : hooguit dat j3 "niet lekker voelt"
 jansteen 3d*:  p2 is laag, beter j4 hoog daarom
 imp NR : oh, ok
 jansteen 3d*:  Tweede argument: gezien d16 en q16 is het centrum belangrijker
]
;B[iq]
;W[kn]C[
 imp NR : en wat g3?
 jansteen 3d*:  g3 ipv j3?
 imp NR : ja?
 jansteen 3d*:  Nee, da's "nurui"
 imp NR : niet genoeg druk?
 imp NR : ok
 jansteen 3d*:  Ja, precies
 imp NR : (da's hetzelfde :)
 jansteen 3d*:  Ik laat jouw trouwens continue de zwarte zetten raden, ok? :)
 imp NR : goed: ik geef eerst de zetten die bij me opkomen, dan een keuze ok?
 jansteen 3d*:  ok
 imp NR : met name aan wat bij mij opkomt kun jij zien wat mis is bij mij:)
 jansteen 3d*:  :)
 jansteen 3d*:  Bijvoorbeeld: Henk moet meer slapen :)
 imp NR : o7, r3, evt j5. :)
 imp NR : r3
 jansteen 3d*:  Ok, ik denk dat j5 verkeerde richting is
 jansteen 3d*:  o7 heb ik gespeeld
 imp NR : denk ik ook:)
 imp NR : o7 zal wel normaal zijn, maar
 jansteen 3d*:  r3 is big, maar niet urgent
 imp NR : r3 big &basis
 jansteen 3d*:  o7 heeft als voordeel dat het indirect de invasie op f3 helpt te voorkomen
 imp NR : ik doe normaal o7, maar nu ga je piekeren:)
 jansteen 3d*:  ja, precies
 jansteen 3d*:  Net als in je eigen partijen :)
 imp NR : :)
 imp NR : ok
]
;B[nm]C[
 imp NR : ik heb geloof ik af en toe een slechte conn.
]
;W[nk]C[
 jansteen 3d*:  Dat zou kunnen, ik moest ook twee keer inloggen
 imp NR : m8, m7, overal daar:)
 jansteen 3d*:  Nog andere opties?
 Chuckles 7k*: what is this game?
 imp NR : r3, l2, q8
 jansteen 3d*:  My game against Yasuda, 8p
 jansteen 3d*:  Ues, q8 is normal, m7 and m8
 jansteen 3d*:  Ues = Yes
 imp NR : q8
]
;B[ll]C[
 jansteen 3d*:  According to Yasuda q8 and m8 are equivalent, both good
 imp NR : i don't like m7
 jansteen 3d*:  Right, me neither
 imp NR : ok
 jansteen 3d*:  m7 is what white wants, induce and invade f3
 imp NR : yep:)
]
;W[fp]C[
 jansteen 3d*:  Other people may join to guess black's next move
 jansteen 3d*:  I wait playing black's move till suggestions have been made
 imp NR : j5, ...
 Chuckles 7k*: k5
 jansteen 3d*:  My next move was best according to Yasuda
 Chuckles 7k*: sounds good to me :)
 jansteen 3d*:  I didn't see it yet
 firefly 1d : l3
 jansteen 3d*:  l3 Yasuda commented on: "That's the way to loose the game"
 imp NR : f3
 imp NR : hane, then cut
 jansteen 3d*:  f3 would sacrifice j3
 Chuckles 7k*: g4 first perhaps?
 imp NR : g5?
 jansteen 3d*:  g4 is right spirit
 jansteen 3d*:  right imp
]
;B[go]C[
 imp NR : considered that a moment, but seems overplay:)
 jansteen 3d*:  f4 is close to overplay, not quite but g5 is severe counter
 Chuckles 7k*: i thought so too
]
;W[hp]C[
 imp NR : g4 only
 jansteen 3d*:  right
]
;B[gp]
;W[hq]C[
 imp NR : g3 o
]
;B[gq]
;W[gr]C[
 jansteen 3d*:  next?
 imp NR : f3 only:)
 firefly 1d : h5
 jansteen 3d*:  h5 I played
 Chuckles 7k*: i'm waiting for k5?
 jansteen 3d*:  k5 strengthens white and thus weakens p4 group, don't play k5 Chuckles
 Chuckles 7k*: ok, thanks
 jansteen 3d*:  Best here is f3, good imp :)
]
;B[ho]
;W[ip]
;B[fr]
;W[hr]C[
 imp NR : this kills aji j3 stone, no?
 jansteen 3d*:  next?
 jansteen 3d*:  Right imp, that's why f3 is better
 Chuckles 7k*: is d9 extension way too soon?
 jansteen 3d*:  next?
 imp NR : defend corner somehow, thinking...
 jansteen 3d*:  That's the right idea imp
 jansteen 3d*:  r3 big, but again not urgent now
 firefly 1d : k7
 imp NR : problem is w e2 aji with many defence moves
 jansteen 3d*:  k7 tempting, but locally another move is better
 jansteen 3d*:  We will come to k7 issue later
 imp NR : c5?
 Chuckles 7k*: f5?
 jansteen 3d*:  c5 with e2 aji is not very big
 jansteen 3d*:  Right Chuckles
]
;B[fo]C[
 jansteen 3d*:  This is only move according to Yasuda
 Chuckles 7k*: thickens and covers e2 :)
 imp NR : leaves c4-aji?
 jansteen 3d*:  Black convert the position to thickness, so territory will come automatically
 jansteen 3d*:  c4 will result in a good result for black
 jansteen 3d*:  Black has hands free to fight severely
 imp NR : not now, but later:)
 jansteen 3d*:  :)
 imp NR : but ok, f5 is nice move
 jansteen 3d*:  Ok white now patches up weaknesses around o9, how?
 jansteen 3d*:  Let me ask differently:
 imp NR : p7?
 jansteen 3d*:  When black's to move, what would be a good move around o7 stone?
 firefly 1d : through n7 and forcing?
 jansteen 3d*:  p7 is right direction
 imp NR : well, q8 then:)
 Chuckles 7k*: p9 i would think
 jansteen 3d*:  q8 closer :)
 jansteen 3d*:  p9 Chuckles?
 imp NR : q9 shape...
 jansteen 3d*:  Right imp
]
;W[pk]C[
 imp NR : seems a bit passive:)
 jansteen 3d*:  q9 defends black q8
 jansteen 3d*:  Oh, now I understand your suggestions :(
 jansteen 3d*:  You suggested black's follow-up, I'm sorry
 imp NR : r14 now
 jansteen 3d*:  Next move is urgent again
 firefly 1d : now k7?
 jansteen 3d*:  imp, q9 not passive, it sets up m10 and r14
 imp NR : true:)
 jansteen 3d*:  k7 is gote on bottom, so it would leave a cut for free
 imp NR : m5?
 jansteen 3d*:  m5 is defensive move
 jansteen 3d*:  Next move is strategically important
 jansteen 3d*:  Think globally
 imp NR : d10 very very big
 jansteen 3d*:  d10 big but not urgent
 Chuckles 7k*: r 12 perhaps?
 jansteen 3d*:  r12 is very big but again wrong direction
 jansteen 3d*:  r3 big, but move played is bigger
 firefly 1d : perhaps m10?
 Chuckles 7k*: I like r5 for corner move.
 jansteen 3d*:  r3 is there for emergency
 jansteen 3d*:  yes firefly!
]
;B[lj]C[
 jansteen 3d*:  This is the 10 point move according to Yasuda
 imp NR : ok
 firefly 1d : now closing left side much bigger
 jansteen 3d*:  m10 shines over upper part of the board
 jansteen 3d*:  m10 reduces r14 value
 jansteen 3d*:  m10 prevents that black p4 becomes a weak group
 jansteen 3d*:  many meanings
]
;W[cj]C[
 imp NR : je zei iets van "cut remaining" dacht ik
 jansteen 3d*:  No direwolf, that would be a nice moment to take the big point r3
 imp NR : c12 only?
 jansteen 3d*:  Right, c12 is correct
]
;B[ch]C[
 jansteen 3d*:  c13 in this kind of circumstances is "nurui", soft, lukewarm
 jansteen 3d*:  c12 is only move
]
;W[bo]C[
 imp NR : oeps:)
 jansteen 3d*:  White is sabaki-ing his group
 jansteen 3d*:  Not trick, b5 is good move, makes c3 and c7 miai
 jansteen 3d*:  A normal move
 jansteen 3d*:  Which point, haetgue?
 XH 30k : #what
 Chuckles 7k*: c7 only good if b can get k7
 jansteen 3d*:  Ok, pls vote for either c7 (around) or b4
 XH 30k : I think c6
 imp NR : b4/c4 very passive...
 Chuckles 7k*: b4
 firefly 1d : c7
 imp NR : is b7 possible?
 jansteen 3d*:  c7 around, imp
 imp NR : otherwise i choose c6:)
 firefly 1d : e11
 jansteen 3d*:  Yes, shouzhuo, o5 slow, that's right
 XH 30k : nihao
 jansteen 3d*:  But Yasuda said about r5: "slow but steady and thick"
 jansteen 3d*:  not r5, o5, sorry
 jansteen 3d*:  Yes, shouzhou, Yasuda suggested as an alternative just ikken-tobi for o5
 jansteen 3d*:  With miai of q8 pressing and k4 pincering
 jansteen 3d*:  ok, the game... Chuckles won the jackpot
]
;B[bp]C[
 jansteen 3d*:  This is best move
 jansteen 3d*:  lower-left corner is too big to give to white
 jansteen 3d*:  Yes David :) sorry
 jansteen 3d*:  Hi :)
 jansteen 3d*:  Yesterday evening David
]
;W[co]
;B[cp]
;W[cm]C[
 imp NR : let's wait and see:)
 jansteen 3d*:  No shouzhou, I start to make mistakes quite soon now
 jansteen 3d*:  So far, black only made one bad move: h5
 jansteen 3d*:  Next move?
 jansteen 3d*:  Sure David, I thought it would be useful to analyse this game
 Chuckles 7k*: r12
 imp NR : my choice between r14, k16, and e11
 firefly 1d : d10?
 jansteen 3d*:  imp got it, but which one?
 imp NR : k16
]
;B[jd]C[
 jansteen 3d*:  again 10 point move
 imp NR : jan is giving a quizz:)
 jansteen 3d*:  Good question direwolf
]
;W[kk]C[
 jansteen 3d*:  oh, moment, mistake
]
;B[lk]
;W[cf]C[
 jansteen 3d*:  sory, forgot kikashi
 jansteen 3d*:  next?
 jansteen 3d*:  What's funny direwolf? :)
 jansteen 3d*:  Oh :)
 jansteen 3d*:  Not Dutch David, Japanese :)
 jansteen 3d*:  right
 imp NR : d14. what else?
]
;B[df]
;W[de]
;B[ee]
;W[ce]C[
 jansteen 3d*:  Next?
 imp NR : d13 or c16, that's the Q:)
 jansteen 3d*:  But you knew that, right David? :)
 imp NR : d13
 jansteen 3d*:  right imp, d13 or c16
 Chuckles 7k*: c16, use d14 stone for shape?
 jansteen 3d*:  I thought so too shouzhuo
 jansteen 3d*:  I played c16, d13 is better
 jansteen 3d*:  Shall I show likely continuation?
]
;B[cd]C[
 imp NR : ok:)
]
;W[dg]
;B[ef]
;W[cg]
;B[eg]
;W[dh]
;B[ji]C[
 jansteen 3d*:  Now b13 is usual joseki
 jansteen 3d*:  But considering lower-left white group, b13 here is risky: black will b12
 jansteen 3d*:  So white's best here is...
]
;W[ed]C[
 jansteen 3d*:  And next black move is only, which one?
 imp NR : b has no complaints here, as far as i can see:)
 imp NR : f14 or so
 jansteen 3d*:  Right f14
]
;B[eb]C[
 jansteen 3d*:  Only move
 jansteen 3d*:  Please note that this sequence created options for black in lower-left
 jansteen 3d*:  For example:.....
]
;W[fd]C[
 jansteen 3d*:  Sorry, I made another mistake :(
 jansteen 3d*:  c7 is wrong, should be c8
 jansteen 3d*:  Hmm, very annoying, sorry :(
 imp NR : just move it back, we forgive you:)
 jansteen 3d*:  But now I can not show you black's aji
 jansteen 3d*:  I can not move stones in teach mode
 imp NR : black has c7-aji? :)
 jansteen 3d*:  No, b9 aji
 jansteen 3d*:  b9, b10, c7
 imp NR : start game anew?
 jansteen 3d*:  Against top pros h3 is not enough, shouzhuo
 imp NR : it should be at c8, that's the joke:)
 jansteen 3d*:  As I will show you soon, only one mistake can ruin the whole game
 jansteen 3d*:  I never played 5-7p range pro's
 jansteen 3d*:  Well, for the rest of the game c7 position is not important
 imp NR : that sounds ominous:)
 jansteen 3d*:  I rewind to d13 now
 jansteen 3d*:  haha, imp
 jansteen 3d*:  My board is a mess
 jansteen 3d*:  jesus, computers :(
 jansteen 3d*:  I reload
 imp NR : ok, you'r #1 now jan:)
 imp NR : :)
 jansteen 3d*:  sorry :)
 jansteen 3d*:  Black played c16, Yasuda of course prefered d13 here
 jansteen 3d*:  right
 jansteen 3d*:  ok, we're back
 jansteen 3d*:  Yes, c16 big, but d13 more important since it keeps white seperated
 jansteen 3d*:  Next?
 imp NR : difficult now
 imp NR : " e13 only?
 firefly 1d : e13
 jansteen 3d*:  e13 is move played
 jansteen 3d*:  not 10 point move
 imp NR : b16 alt
 jansteen 3d*:  b16 2 points :)
 imp NR : shit, i quit this game:)
 jansteen 3d*:  haha
 imp NR : e16 third choice
 jansteen 3d*:  This is the point where black definitely lost control over the game
 jansteen 3d*:  Yes imp, e16!
 jansteen 3d*:  But why?
 imp NR : can't let w invade there or cut
 jansteen 3d*:  There is a very clear reason
 jansteen 3d*:  Of course, points made by you are valid, but I want to hear clearer reason
 imp NR : w b16, if b blocks then w cuts
 jansteen 3d*:  No imp, white doesn't need b16 to cut, it works immedtaely
 jansteen 3d*:  immediately
 jansteen 3d*:  yes shouzhuo!
 jansteen 3d*:  yes!
 jansteen 3d*:  shouzhuo 10 points
 imp NR : bravo:)
 jansteen 3d*:  Yasuda gave following continuation: black e16, white e13, black r11
 jansteen 3d*:  ok?
 imp NR : yes
 imp NR : similar to f3:(
 jansteen 3d*:  Right shuozhuo, black still better that way, but not by much anymore
 jansteen 3d*:  Reason is that white got territory at left side whereas he should have had a weak group
 jansteen 3d*:  (by black's c16 at d13)
 jansteen 3d*:  Right imp
 jansteen 3d*:  Here: next?
 twofar NR : now e16 is really gote
 jansteen 3d*:  right twofar
 Chuckles 7k*: at least q12
 jansteen 3d*:  b16 might be ok
 imp NR : me too
 twofar NR : move on right side for sure
 jansteen 3d*:  imp also b16?
 imp NR : f17 alternative
 jansteen 3d*:  Black played this variation to take next point....
 jansteen 3d*:  Follow-up of m10
 imp NR : this is better than e12
 jansteen 3d*:  This point is very nice
 Chuckles 7k*: yes nicer shape than r12
 Chuckles 7k*: r12 is a wait and see type move no?
 jansteen 3d*:  However, white can cut at d16
 imp NR : hope for you that k11 offered some help:)
 jansteen 3d*:  No shouzhuo, k11 is direction here, except for d16cut
 jansteen 3d*:  I made a reading mistake quickly here, I will show final moves

;W[bd]C[
 jansteen 3d*:  Black looses this semeai, and resigned
 imp NR : yep:(
 jansteen 3d*:  What's a stone tower shoushuo?
 imp NR : b17-c17; b15-a16
 twofar NR : so if b f16 giving the corner up in sente insted?
 jansteen 3d*:  In that case white got too much territory twofar
 twofar NR : ok!
 imp NR : but here does not work i see now?
 jansteen 3d*:  I felt sorry for my opponent here since the game was so short
 jansteen 3d*:  But anyway lots of points of interest
 firefly 1d : kib thx jan
 jansteen 3d*:  According to Yasuda the sacrifice of the corner would settle the game, shouzhuo
 imp NR : o it does, sorry again
 jansteen 3d*:  Black too far behind that way, white's left side is too big
 imp NR : thanks jan, intyeresting:)
 imp NR : many good moves by b, a pity it ended this way
 jansteen 3d*:  What suprised me while analysing the game with Yasuda sensei is that it only takes...
 jansteen 3d*:  two mistakes to loose a h3 game
 jansteen 3d*:  Of course the e16 cut is extremely sever
 imp NR : it's loosing a fight like this that really hurts, not so much a mistake?
 jansteen 3d*:  But anyway, when black chooses a quiet variation (like e18 at d18) the game would be close
 jansteen 3d*:  The two moves which spoiled the game were: c16 and d13
 jansteen 3d*:  oh, e13 (not d13)
 jansteen 3d*:  Ok, maybe more of this stuff later this week or in the weekend
 jansteen 3d*:  Agree shouzhuo, d13 very bad, but also c16 very bad
 jansteen 3d*:  thanks for sharing ideas :)
 jansteen 3d*:  till later!
