 Explorer NR : Let's Go!
]
;W[dd]WL[1762]C[
 GoAhead NR : Let's speak English?
 Explorer NR : yeah
]
;B[qc]BL[1749]
;W[qq]WL[1747]
;B[co]BL[1740]C[
 GoAhead NR : I studied some Ex-games on the web ...
 GoAhead NR : seems that Ex is somewhat stronger than the programs below.
 Explorer NR : I hope so...but maybe not enough to stop GoAhead
]
;W[pd]WL[1730]C[
 Explorer NR : say so you know all its weaknesses
]
;B[qd]BL[1708]
;W[pc]WL[1721]
;B[qe]BL[1697]C[
 Explorer NR : sh
 GoAhead NR : Does Ex know this sequence as joseki?
 Explorer NR : well it is not joseki...
 GoAhead NR : I think Q15 instead of R15 was joseki
]
;W[lc]WL[1690]
;B[ph]BL[1682]C[
 GoAhead NR : what's your personel strength, Martin?
 Explorer NR : 5d in europe, 6d here
]
;W[pn]WL[1648]C[
 Explorer NR : I don't know o17, joseki is q15 or q14
]
;B[pk]BL[1646]
;W[cg]WL[1623]
;B[kq]BL[1631]C[
 GoAhead NR : So, you are at least the strongest go-programming player ...
 Explorer NR : no, many are strong players
 GoAhead NR : Since I'm only 7k, I would appreciate any go-related comments
]
;W[dr]WL[1574]
;B[er]BL[1615]C[
 Explorer NR : wow, fancy :)
]
;W[eq]WL[1559]C[
 GoAhead NR : what do you think about white's invasion so soon?
 Explorer NR : its ok. but e17 more normal
 GoAhead NR : I see.
]
;B[cr]BL[1590]
;W[dp]WL[1552]
;B[cq]BL[1558]
;W[fr]WL[1545]
;B[ds]BL[1541]
;W[fo]WL[1537]C[
 Explorer NR : q9 was bad, too small
]
;B[fq]BL[1520]
;W[gq]WL[1523]C[
 Explorer NR : explorer does not know this sabaki...
 GoAhead NR : GoAhead also not - but joseki sequence
]
;B[ep]BL[1482]
;W[fp]WL[1515]
;B[eq]BL[1467]C[
 Explorer NR : good result for w
]
;W[hr]WL[1476]C[
 GoAhead NR : you shouldn't have said that
 Explorer NR : too bad
]
;B[do]BL[1448]C[
 GoAhead NR : the problem: Somewhere the Joseki library ends...
]
;W[ec]WL[1443]
;B[nq]BL[1434]C[
 GoAhead NR : cut at g4 is severe
 GoAhead NR : should black have cut immediately?
]
;W[cd]WL[1407]
;B[ir]BL[1418]C[
 GoAhead NR : C16 bad move
 Explorer NR : no, o3 was fine
 Explorer NR : j2 strange
]
;W[iq]WL[1375]C[
 GoAhead NR : struggeling for life at edge?
]
;B[jr]BL[1396]C[
 Explorer NR : trying to steal your eye space here...
]
;W[ho]WL[1323]C[
 GoAhead NR : Anyway, white should handle it's left bottom group lightly, a thing that GoAhead is not able to do.
 Explorer NR : haha, you're scared!
 GoAhead NR : yes.
]
;B[dk]BL[1378]C[
 Explorer NR : ex evaluates the top side invasion much too low
]
;W[lf]WL[1285]C[
 Explorer NR : you will get a HUGE area there
]
;B[ci]BL[1359]C[
 GoAhead NR : How does Ex judge the score?
 Explorer NR : B+11, but it is just a random number
 GoAhead NR : I have a close match W+0 (!)
 Explorer NR : I think it is close, too, but W is a bit better
 GoAhead NR : I'm worried about white's right lower corner
]
;W[nn]WL[1204]
;B[ei]BL[1345]C[
 GoAhead NR : also big black mojo.
 GoAhead NR : (more or less already territory)
 Explorer NR : only 1/3 of yours 
]
;W[id]WL[1162]
;B[fg]BL[1329]C[
 GoAhead NR : good move!
 Explorer NR : yes, but too late
 GoAhead NR : Ex reduces nicely
]
;W[qb]WL[1128]
;B[rb]BL[1314]C[
 Explorer NR : r7 r8 area is big
 GoAhead NR : Here we have a problem of GoAhead: defending his mojos is a problem
]
;W[pb]WL[1074]C[
 Explorer NR : score now W+15
]
;B[pp]BL[1296]C[
 Explorer NR : hmm, helping you
 GoAhead NR : W+3
 Explorer NR : W+6
 GoAhead NR : will Ex cut after r4?
 Explorer NR : no, guess not
 GoAhead NR : then yes
]
;W[qp]WL[1023]
;B[pq]BL[1283]C[
 Explorer NR : at least this group gets a bit stronger
 GoAhead NR : not a bad game for computer vs. computer so far, I think
]
;W[po]WL[982]C[
 Explorer NR : agree. I've seen worse things happen...
 GoAhead NR : indeed.
]
;B[qr]BL[1260]C[
 Explorer NR : haha, copying your moves
 GoAhead NR : all groups are strong now (except white's lower middle, but not too bad)
]
;W[rr]WL[921]C[
 GoAhead NR : dito.
]
;B[pr]BL[1245]C[
 GoAhead NR : important move now. If you were white - where to play, Martin?
 Explorer NR : r8, or forcing around e7
]
;W[ql]WL[871]C[
 Explorer NR : wow
 GoAhead NR : Hey, GoAhead agrees with a 6d !!!
]
;B[qk]BL[1226]
;W[pl]WL[840]
;B[ol]BL[1213]C[
 GoAhead NR : S9 better instead
 Explorer NR : s8 better for both
 Explorer NR : or s9 for you
 Explorer NR : p8 very bad
]
;W[ok]WL[795]C[
 GoAhead NR : now the fun has started!
]
;B[nl]BL[1200]C[
 Explorer NR : in this fight, B has nothing to gain and much to lose
 GoAhead NR : what could he lose? I don't see any weaknesses.
]
;W[nk]WL[743]
;B[ml]BL[1187]C[
 Explorer NR : p8 group is weak, and around r11 weak too
 GoAhead NR : on the contrary, white might get into troubles with his corner *and* with his lower edge group
 GoAhead NR : well, but you are the 6d.
]
;W[oi]WL[670]C[
 GoAhead NR : B(s8) now?
 GoAhead NR : Ex takes more time now?
 Explorer NR : sorry, I was out of the room
]
;B[rk]BL[1031]C[
 Explorer NR : hmm strange
]
;W[rl]WL[606]C[
 GoAhead NR : things are getting calmly now
]
;B[kn]BL[1014]C[
 GoAhead NR : very good move!
 Explorer NR : q11 must be protected, B in troubles
 GoAhead NR : W in troubles now, I think
]
;W[pi]WL[526]
;B[qi]BL[998]C[
 Explorer NR : maybe r12 would have worked
 GoAhead NR : interesting. Now B's shape is good, isn't it?
 Explorer NR : no, B will lose one side or the other
]
;W[qh]WL[463]
;B[rh]BL[960]
;W[qg]WL[419]C[
 GoAhead NR : W(r10) instead of r13 better?
 Explorer NR : r13 is best
]
;B[pg]BL[915]C[
 Explorer NR : ouch. does not work
 GoAhead NR : I'm not sure that GoAhead finds S11 now
 Explorer NR : I hope not :)
]
;W[rg]WL[358]C[
 GoAhead NR : that's computer go
]
;B[ri]BL[874]C[
 Explorer NR : Q14 and you're fine
 GoAhead NR : yes, I see.
 GoAhead NR : GoAhead now takes more time, trying to read out life& death of created groups ...
]
;W[pf]WL[277]
;B[pe]BL[846]C[
 Explorer NR : trying to trick you 
 GoAhead NR : interesting aproach: giving up two stones for escape
 GoAhead NR : what's the trick, please tell me
 Explorer NR : trick isif you answer p15
 GoAhead NR : ok.
]
;W[og]WL[178]C[
 Explorer NR : but no suck luck, all dead
]
;B[oe]BL[806]C[
 GoAhead NR : difficult for B now - 2 very weak groups
 GoAhead NR : W+35 now
 Explorer NR : yes, B completely lost here
 GoAhead NR : GoAhead consideres B stones around S11 as dead.
]
;W[oh]WL[106]C[
 GoAhead NR : oops.
]
;B[em]BL[783]C[
 Explorer NR : don't know why it missed q11, it looks so urgent
 GoAhead NR : I agree. I'm often working on such obvious moves
 GoAhead NR : Let's see what happens here
 GoAhead NR : this time, you are in offense
 Explorer NR : ex considers r17 group dead, too
 GoAhead NR : GoAhead not. And S11?
 Explorer NR : both groups dead
 GoAhead NR : is entering byo-yomi
]
;W[if]WL[2697]C[
 GoAhead NR : oh, oh ...
]
;B[gl]BL[747]C[
 GoAhead NR : score?
 Explorer NR : W+100
 GoAhead NR : whow!
]
;W[ih]WL[2642]C[
 Explorer NR : but that is pessimistic, I think it is 50-60 now
 GoAhead NR : hmm, I'm not pleased how W handels his weak bottom group ...
]
;B[im]BL[726]C[
 GoAhead NR : now, W must struggle ...
 GoAhead NR : W+44
]
;W[li]WL[2592]C[
 GoAhead NR : oh, oh ...
 GoAhead NR : I don't understand my program.
]
;B[kk]BL[699]C[
 GoAhead NR : If B kills W bottom group, it's a close match again?
 Explorer NR : maybe not close, but closer :)
]
;W[od]WL[2542]
;B[me]BL[659]C[
 GoAhead NR : B can live in upper right corner s14, t13, s19
 Explorer NR : agree
 GoAhead NR : then B leads!
]
;W[nd]WL[2452]C[
 Explorer NR : but Life&Death thinks s15 is best, and that it does not work
]
;B[hj]BL[631]C[
 GoAhead NR : why did Ex play N15 if stones considered as dead? - invasion?
 Explorer NR : the problem is that life&death does not know about connections to other groups
 Explorer NR : it only knows about 2 eyes
 GoAhead NR : I see, also have problems with that.
]
;W[le]WL[2381]
;B[bh]BL[610]C[
 GoAhead NR : but even then, S14 is natural
 Explorer NR : yes, don't know what is wrong
 GoAhead NR : W stones at bottom are marked "?", but GoAhead refuses to play there!
]
;W[ne]WL[2300]C[
 GoAhead NR : ouch
 Explorer NR : same here, it thinks W unsettled, but cannot find an attacking move
 GoAhead NR : you have another chance ...
]
;B[mf]BL[584]C[
 Explorer NR : ouch2
 GoAhead NR : you could say that!
 GoAhead NR : guess next move!
 Explorer NR : o14
]
;W[nf]WL[2208]C[
 GoAhead NR : good bet.
 GoAhead NR : N13 now?
 GoAhead NR : will Ex invade on upper side somewhen?
 Explorer NR : no invasion, just f15 or so
 GoAhead NR : well, f15 is big
]
;B[bg]BL[531]C[
 GoAhead NR : good
 Explorer NR : also thinking about k4 now
]
;W[cf]WL[2146]
;B[ge]BL[512]C[
 Explorer NR : wrong shape
 GoAhead NR : could you explain, please?
 Explorer NR : keima is easy to cut. at least it should play h13 first, then here
 GoAhead NR : many ways to kill W stones at bottom
 Explorer NR : no, hard to kill
]
;W[bf]WL[2091]C[
 GoAhead NR : ouch3!
]
;B[gc]BL[494]C[
 GoAhead NR : Ex is pretty good in reducing
 Explorer NR : especially reducing its own groups to dead 
 GoAhead NR : (funny) 
 GoAhead NR : W+26
 Explorer NR : W+68 
]
;W[hc]WL[1997]C[
 GoAhead NR : so we have two dead groups on board, which are not dead ?!
 Explorer NR : please explain 
 GoAhead NR : well, R15 may live, H5 may life, but no program plays there
 Explorer NR : I know - but why? 
]
;B[gb]BL[473]
;W[fb]WL[1936]
;B[gh]BL[447]C[
 GoAhead NR : GoAhead doesn't see any good moves at bottom, and R16 group is too large to be calculated dead or alive
 Explorer NR : g16 a problem
 GoAhead NR : GoAhead wil not play G16, be sure
]
;W[hb]WL[1855]
;B[jp]BL[424]C[
 Explorer NR : here we go
 GoAhead NR : is Ex good in killing?
 Explorer NR : yes! especially killing itself!
 GoAhead NR : (funny) Please wait a minute, I must make a coffee, Martin
]
;W[gd]WL[1781]C[
 GoAhead NR : I WAS WRONG!
]
;B[he]BL[315]C[
 Explorer NR : ouch4
 GoAhead NR : ok, coffe mashine is doing it's work. There's definitely a bug in my code concerning the decision whether to play locally or play tennuki.
 GoAhead NR : I must look at that.
]
;W[fd]WL[1700]C[
 Explorer NR : how do you decide that?
]
;B[ie]BL[289]C[
 GoAhead NR : I try to evaluate the strength of attacked groups and strengths of surrounding groups
 Explorer NR : then?
 GoAhead NR : there's a switch, forcing GoAhead to generate only local moves - or not
]
;W[je]WL[1621]C[
 GoAhead NR : When I play Go, I'm often in "local mode"
 Explorer NR : I do something similar, but very crude: I increase local values for some
 Explorer NR : types of moves
]
;B[jd]BL[225]C[
 Explorer NR : oops5
 GoAhead NR : Explorer bounces back?
 Explorer NR : if you k14 ex just loses points that's all
]
;W[sd]WL[1548]C[
 GoAhead NR : *if* ...
 Explorer NR : (smile)
 GoAhead NR : (grumble)
]
;B[jc]BL[185]C[
 Explorer NR : oops9999
 GoAhead NR : oh, number was 6!
 Explorer NR : oops6
 Explorer NR : at least it loses points IN SENTE!
]
;W[jf]WL[1444]C[
 GoAhead NR : (smile!)
]
;B[hd]BL[162]C[
 GoAhead NR : coffee is ready - cheers!
 Explorer NR : I switched to milk...
 GoAhead NR : oops, my fault! Ex was a genius!
 Explorer NR : thanks!
]
;W[jb]WL[1378]C[
 Explorer NR : j18 would be good now
]
;B[kb]BL[112]C[
 Explorer NR : this bad, if you j18 now
 GoAhead NR : too complicated for me. Why not simply J17? - bigger?
 Explorer NR : if I j17, you j18 and are fine
 Explorer NR : if I j18, you must g19, then j17, you capture, then I can L18
 GoAhead NR : ok.
]
;W[ja]WL[1257]C[
 GoAhead NR : strange
 wnewman NR :  not b 199 @ j18 
 Explorer NR : j18 still good
 Explorer NR : but ex cannot read 'capture one of these'
]
;B[ib]BL[23]C[
 Explorer NR : wow!
]
;W[ga]WL[1211]C[
 GoAhead NR : B has pretty good chances to win now
 GoAhead NR : W's mojo is devasted
 Explorer NR : if g3 dies it is close game now
 GoAhead NR : Ex *has* bounced back !!!
 Explorer NR : is entering byo-yomi
]
;B[ma]BL[2633]C[
 Explorer NR : oops7
 Explorer NR : switched back to self-destruction :(
]
;W[ia]WL[1156]C[
 GoAhead NR : well, doesn't hurt so much, I think
 GoAhead NR : B is connected and N19 probably large
 GoAhead NR : am I wrong?
 Explorer NR : capturing stones would have been much safer and also bigger
]
;B[ic]BL[2448]C[
 GoAhead NR : one could even think about W(l17) now
 Explorer NR : no, then L19
 GoAhead NR : oh yes, my fault
]
;W[ha]WL[1104]C[
 GoAhead NR : B(h19) bad. better capture instead
 Explorer NR : same thing
]
;B[mb]BL[2386]C[
 Explorer NR : ???????
 GoAhead NR : Ex doesn't like to defend cuts?
 Explorer NR : it prefers to build an eye here... big bug
 Explorer NR : one eye not enough
 GoAhead NR : might have something to do with "connection" to N15 group?
 Explorer NR : no, just a bug
]
;W[mg]WL[1013]C[
 GoAhead NR : ???????
 GoAhead NR : Ex will now connect?
 Explorer NR : probably not, it will continue working on an eye 
]
;B[ka]BL[2310]C[
 Explorer NR : it thinks eye is a little bit better than connection
 Explorer NR : because of the extra points
]
;W[fa]WL[958]C[
 GoAhead NR : building eyes when possible to connect is bad
 Explorer NR : why bad? If it is TWO eyes I mean
 GoAhead NR : ok, you are the 6d
]
;B[kc]BL[2261]C[
 GoAhead NR : has entered byo-yomi again
 Explorer NR : wow
 GoAhead NR : although eye is not completed!
 Explorer NR : if you have several ways to make it safe, you want to maximize points, no?
 GoAhead NR : I see. But you must be careful ...
 Explorer NR : agree, connecting is safer
]
;W[mc]WL[2623]C[
 Explorer NR : L17, m18 almost same value. just lucky
 GoAhead NR : bad luck for GoAhead
]
;B[ke]BL[2218]C[
 Explorer NR : oh my god! it is now attacking the big white group!!!!
 GoAhead NR : R16 group is still marked "?". GoAhead will lose more moves there
]
;W[nb]WL[2546]C[
 GoAhead NR : outcome of the game is decided by W's group around G3.
 Explorer NR : probably. but many other things can go wrong
 GoAhead NR : since I have a bug here, I think you win
]
;B[na]BL[2141]C[
 Explorer NR : still attacking you...
]
;W[oa]WL[2492]C[
 Explorer NR : most of your territories get evaluated as 0 eyes
 GoAhead NR : but dead stones inside - almost equal to eyes, right?
 Explorer NR : it is just a bug, nothing rational
]
;B[oc]BL[2077]C[
 Explorer NR : haha!
 GoAhead NR : funny!
 Explorer NR : does that kill you now or what :))
 GoAhead NR : maybe!
]
;W[re]WL[2433]C[
 Explorer NR : I hope ex thinks you're dead now
 GoAhead NR : what's his score?
]
;B[sg]BL[1991]C[
 Explorer NR : B+8
 GoAhead NR : W+14
]
;W[pj]WL[2367]C[
 GoAhead NR : oh, oh
 Explorer NR : s14 gives Ko
 GoAhead NR : can Ex play ko?
 Explorer NR : no, you still win
 Explorer NR : it knows about Ko, but is not very good at it
 Explorer NR : doing a deep L&D search now. hope it helps
 wnewman NR :  w 140 @ q10 seems to be a characteristically non-human way to solve the problem
 GoAhead NR : B(s14) r14 t14 s17 seems to win semiai
 Explorer NR : agree
]
;B[sj]BL[1852]
;W[rf]WL[2301]C[
 Explorer NR : solid. no chance now
 GoAhead NR : agree
 GoAhead NR : (but I'm not sure, if GoAhead finds B(r10) t12
 GoAhead NR : (he should, however)
]
;B[sh]BL[1750]C[
 Explorer NR : why not? looks easy
 GoAhead NR : I never know what comes out if GoAhead calculates L&D
]
;W[qj]WL[2251]
;B[hg]BL[1703]C[
 Explorer NR : good. I was worrying about g14 later
 GoAhead NR : yes, I've been looking at that
]
;W[ig]WL[2189]C[
 GoAhead NR : GoAhead has calculated both B groups dead now - W+26
]
;B[op]BL[1662]C[
 Explorer NR : ex thinks W dead too -> B+8
 Explorer NR : I mean W g3 group
 GoAhead NR : P4 bad, s1 obvious huge yose move
]
;W[om]WL[2119]C[
 Explorer NR : s1 is #3 on explorer's list
]
;B[ef]BL[1626]C[
 Explorer NR : n5 is very big too, but it does not see
 GoAhead NR : GoAhead has changed to endgame mode
]
;W[kf]WL[2061]
;B[kd]BL[1589]
;W[mp]WL[2001]C[
 Explorer NR : what is different in endgame mode?
 GoAhead NR : more points for endgame calculations
]
;B[mq]BL[1509]
;W[jo]WL[1933]C[
 GoAhead NR : this time, he connects
 Explorer NR : yes I was afraid he would play something stupid to make eyes
 Explorer NR : here we go!
]
;B[ko]BL[1462]C[
 Explorer NR : may I ask a question: if you have a workstation, why use the slow machine?
 GoAhead NR : good question. My program is written in special GFA-Basic for Atari - no chance to put this on my workstation
 Explorer NR : oh, i c
 GoAhead NR : J4 now and some eye shape
 Explorer NR : is this compiled Basic at least?
 GoAhead NR : yes
]
;W[ip]WL[1862]
;B[lp]BL[1423]C[
 Explorer NR : ex thinks you're alive now, score W+41
 GoAhead NR : hope so
]
;W[in]WL[1810]
;B[mo]BL[1389]C[
 Explorer NR : ouch27
 GoAhead NR : this time, GoAhead has made the correct decision: keep on playing at his weak group
 GoAhead NR : even if cost some stones
 Explorer NR : good
]
;W[mn]WL[1729]
;B[no]BL[1355]C[
 GoAhead NR : M7 not bad now
 GoAhead NR : (but I would prefer H7)
]
;W[km]WL[1656]C[
 Explorer NR : nose tesuji?
 GoAhead NR : no, endgame calculation
 GoAhead NR : (doesn't work)
]
;B[jl]BL[1305]C[
 Explorer NR : ouch 73
]
;W[jm]WL[1570]C[
 GoAhead NR : I have an intesting talk with wnewman now (simultaneously)
 GoAhead NR : K7 ouch
 Explorer NR : what's he saying?
]
;B[hm]BL[1239]C[
 GoAhead NR : he's impressed
 GoAhead NR : also about Ataris and other mashines
 Explorer NR : I think you can beat ego easily. did you look at ex-ego game?
 GoAhead NR : yes, I think so
 GoAhead NR : H7 was vital point?
]
;W[jn]WL[1492]C[
 Explorer NR : did you play test games with ego?
 GoAhead NR : GoAhead usually wins again EzGo share ware
]
;B[lk]BL[1203]C[
 GoAhead NR : oh, GoAhead can connect now!
 Explorer NR : yes
]
;W[dn]WL[1405]

 Explorer NR : did you really d6?
 GoAhead NR : yes
 Explorer NR : ok
]
;W[jq]WL[1331]
;B[kp]BL[1113]C[
 GoAhead NR : Maybe wnewman will try a 9-stone handicap match against GoAhead!
]
;W[ln]WL[1266]C[
 Explorer NR : has entered byo-yomi again
 GoAhead NR : ouch
]
;B[mj]BL[2672]C[
 GoAhead NR : now, it's a crosscut - GoAhead will connect I think
 GoAhead NR : N8 is even sente!
]
;W[mi]WL[1188]C[
 GoAhead NR : damn!
 Explorer NR : I know how it feels
]
;B[gn]BL[2608]C[
 GoAhead NR : yes, it simply hurts
]
;W[mm]WL[1114]C[
 GoAhead NR : uff
 GoAhead NR : what's the score now?
 Explorer NR : about W+40
]
;B[mk]BL[2513]C[
 Explorer NR : W+41
 GoAhead NR : but B(n9) was no point!
 GoAhead NR : GoAhead: W+30
]
;W[ll]WL[1030]C[
 Explorer NR : B was afraid, did not see m8 is sente
 GoAhead NR : I see.
 Explorer NR : this is not a point, too :)
 Explorer NR : do you look for sente moves?
 GoAhead NR : yes, I try during endgame move calculations
]
;B[go]BL[2423]C[
 GoAhead NR : ... just a bit late
 Explorer NR : very good. I don't. only some 'sente' patterns
 GoAhead NR : may have better results than mine
]
;W[gp]WL[966]C[
 GoAhead NR : sounds good, but results are quite bad
 Explorer NR : apparently not. E.g. A14 should be sente pattern, but it does not play it
]
;B[ji]BL[2359]C[
 GoAhead NR : has entered byo-yomi again
 Explorer NR : do you consider rewriting program for faster machines?
 GoAhead NR : that would require lot of time - difficult
 Explorer NR : I am now working on a C++ version of Explorer. About 30% done
 GoAhead NR : good luck with it!
]
;W[ld]WL[2593]C[
 GoAhead NR : B must be careful now
]
;B[kh]BL[2312]C[
 Explorer NR : so I do not work on the Modula code anymore
 GoAhead NR : what is larger: L12 or 3 stones around N19?
 Explorer NR : b thinks this is more urgent than 3 stones, but it is wrong
 Explorer NR : m18 is 8 points
 Explorer NR : this about 4-5
 GoAhead NR : thx
]
;W[lb]WL[2501]C[
 Explorer NR : but you should m18 yourself before m16
]
;B[rs]BL[2266]C[
 Explorer NR : finally!
 GoAhead NR : S1 huge. how many points, Martin?
]
;W[sq]WL[2431]C[
 GoAhead NR : 4 in sente?
 Explorer NR : about 13 for counting purposes, or '4 in sente'
 Explorer NR : sente because you answer. 4 points = o1, t1, t2, t3
]
;B[de]BL[2198]C[
 GoAhead NR : B(d15) bad - invalidates a14
 Explorer NR : agree
]
;W[ce]WL[2326]
;B[af]BL[2159]C[
 Explorer NR : good example of bad technique!
 GoAhead NR : right
]
;W[ae]WL[2248]C[
 GoAhead NR : GoAHead: W+23 - things are getting closer!
 Explorer NR : agree, W+23+komi
 GoAhead NR : GoAhead including komi
 Explorer NR : Ex W+23 on board, so W+28 total
]
;B[ag]BL[2113]C[
 GoAhead NR : J1 would be good sente move
 Explorer NR : but where can I get 30 points? looks hard
 GoAhead NR : probably
 GoAhead NR : (but so many things may happen in computer go)
]
;W[ee]WL[2172]C[
 Explorer NR : if you don't mind I want to play till the end
 GoAhead NR : of course, we do!
 Explorer NR : anything below 60 is close in computer Go!
]
;B[df]BL[2048]C[
 GoAhead NR : will Ex try to invade W's upper left corner?
 Explorer NR : no.
 GoAhead NR : good for GoAhead
]
;W[gi]WL[2095]C[
 GoAhead NR : hmm - strange
 Explorer NR : like d6 before
]
;B[gj]BL[2010]C[
 Explorer NR : aua
 GoAhead NR : weia
 Explorer NR : 4 point loss
 GoAhead NR : E6 was clever against D6 instead
 Explorer NR : clever? well...
]
;W[hi]WL[2000]C[
 Explorer NR : g10, h11 had exactly the same value. bad luck...
]
;B[fi]BL[1972]C[
 Explorer NR : strange, it did not see that h11 is a cut, and a capture
 GoAhead NR : please explain
 Explorer NR : h11 cuts off your stone, and it should also be captured pretty quickly, no?
 GoAhead NR : ok.
 GoAhead NR : sorry, I do not see much today
]
;W[ij]WL[1915]C[
 GoAhead NR : J10 bad again
 Explorer NR : yes, but could become problem for j17 later
]
;B[ii]BL[1881]C[
 GoAhead NR : yes, I just wanted to point this out - but you were faster
 GoAhead NR : (but there's no real danger: W(h12) h14 and nothing happens)
]
;W[hh]WL[1832]C[
 Explorer NR : there may be no real danger with optimal play, but there is a real danger!
 GoAhead NR : (smile)
]
;B[jj]BL[1828]C[
 Explorer NR : see?
 GoAhead NR : yes.
]
;W[hf]WL[1706]C[
 GoAhead NR : Ex is not willing to give away H13 stone?
 Explorer NR : probably
]
;B[gg]BL[1750]C[
 GoAhead NR : oh, oh
 Explorer NR : that's the problem with my local-answer method. L19 block is not local...
 GoAhead NR : W(M19) and K16 stones killed
 Explorer NR : yes
]
;W[gf]WL[1600]C[
 Explorer NR : ex saw it, but local move got priority. too bad
 GoAhead NR : GoAhead saw that M19 takes stones, but G14 also got a huge value - ???
]
;B[is]BL[1675]C[
 GoAhead NR : I hear the toilet flushing ...
 GoAhead NR : OUCH!!! H16/K16 stones are considered dead!
 Explorer NR : same problem here...
]
;W[ff]WL[1507]C[
 GoAhead NR : this move was not calculated according to life&death of B's groups.
 GoAhead NR : (just a sente yose play)
 Explorer NR : f15 would have escaped by Ko
 GoAhead NR : f15 m19
 Explorer NR : ok, resign
