;B[de]BL[1197]C[
 Perception NR : Well, it thinks that the time is 6+20/25, but close enough I guess.
]
;W[cg]WL[1162]C[
 Perception NR : Good luck!  :-)
 Explorer 14k : thanks
]
;B[gg]BL[1172]
;W[ef]WL[1146]C[
 Perception NR : The time bug isn't in perception, it's in my client which is supposed to tell Perception what the time controls are.
]
;B[gc]BL[1149]C[
 Explorer 14k : what bug?
]
;W[ge]WL[1136]C[
 Perception NR : Perception doesn't know the main time period correctly.  It only knows the byo-yomi period.
]
;B[dc]BL[1129]C[
 Perception NR : But this is close enough, at least it won't think way past it's amount of time.
]
;W[ee]WL[1128]
;B[eg]BL[1110]
;W[df]WL[1111]C[
 Perception NR : Explorer plays very solidly!
 Explorer 14k : komi is 8, isnt that too much?
 Perception NR : That's fine.  Whatever is OK.
]
;B[he]BL[1080]C[
 Explorer 14k : there should be rules, but I cannot remember
 Perception NR : . If the game is close enough for komi to matter I'll be surprised, the way these programs play.  :-)
 Perception NR : I think that the komi is supposed to be 5.5
]
;W[hf]WL[1080]C[
 Perception NR : How about if it's between 5.5 and 8, we do a rematch.
 Explorer 14k : I will try to look it up, I also think it is 5.5
]
;B[hd]BL[1016]C[
 Perception NR : Yay!  Wasn't sure that it would get that one.
]
;W[ed]WL[1041]
;B[gf]BL[1015]
;W[fd]WL[1027]C[
 Explorer 14k : ouch!
 Perception NR : I wouldn't get too worried if I were you...
 Perception NR : Can your program read well?
]
;B[bc]BL[981]C[
 Perception NR : Perception won the first two games by reading out semeai's better
]
;W[dd]WL[998]C[
 Explorer 14k : I'm impressed...
 Perception NR : It's surprisingly good at that sometimes.  Other times surprisingly bad.
]
;B[be]BL[945]C[
 Perception NR : D'oh!
]
;W[cd]WL[985]
;B[ch]BL[921]C[
 Perception NR : Double D'oh!
]
;W[bh]WL[957]C[
 Explorer 14k : maybe you'll kill all
 Perception NR : I doubt it.  It looks like explorer will get at least one eye.
 Perception NR : And Perception doesn't know about eyes so it's bad at killing big groups.
 Explorer 14k : haha
]
;B[fe]BL[881]C[
 Perception NR : ??? WHY???
 Perception NR : At least it's sente.  :-|
]
;W[gd]WL[906]C[
 Explorer 14k : maybe not :)
 Perception NR : It's really weird sometimes, the moves it chooses to make.  I guess you must have the same trouble.
 Explorer 14k : how do you choose moves?
]
;B[dh]BL[823]C[
 Perception NR : I do a full board search (2 ply right now)
 Perception NR : That terminates in alpha-beta tactical searches to find liveness of each group
 Perception NR : Then I do an influence function to divvy up the rest
]
;W[ce]WL[862]
;B[hc]BL[820]C[
 Perception NR : How about you?
 Explorer 14k : lots of things, but it really weak on the 9x9
 Perception NR : Ah.  I'm really weak at 19x19.  Hilariously so.
 Perception NR : But after 5 ridiculous moves it turns just boring instead of funny.
]
;W[ff]WL[808]
;B[bi]BL[796]C[
 Perception NR : Looks like I won't kill all.
 Explorer 14k : most of Explorer's knowledge does not apply on 9x9
 Perception NR : Lots of shape information or something?
]
;W[bf]WL[760]C[
 Perception NR : B4 is a good move
 Explorer 14k : yes, and the territory values on 9x9 are very different. 2nd line is good here
]
;B[ah]BL[746]
;W[bg]WL[725]C[
 Perception NR : Oh.  I play 2nd line too much.  Perception thinks playing under a 3rd line stone is a great way to separate it from the edge.
 Explorer 14k : you can see almost all moves are on line 3 and 4
 Explorer 14k : which is vey bad here...
]
;B[eh]BL[717]C[
 Perception NR : Yes.  If perception plays right it will get all the edges.
 Perception NR : But I'm not sure that it will.
]
;W[bd]WL[705]C[
 Perception NR : Explorer can kill the whole UL if it tries...
 Explorer 14k : yes, e8 or f8
]
;B[fb]BL[696]C[
 Perception NR : Yay!  :-)
]
;W[cc]WL[692]
;B[bb]BL[673]C[
 Perception NR : Oops.
]
;W[cb]WL[677]C[
 Perception NR : Close game.
 Perception NR : Maybe the komi will matter.
]
;B[ba]BL[652]C[
 Explorer 14k : lets set komi 5.5
]
;W[ca]WL[656]C[
 Perception NR : OK.  Good.
 Perception NR : Now if only it gives up on the UL and saves the top...
]
;B[hi]BL[631]C[
 Perception NR : Oh wow.
 Perception NR : What a classic.
]
;W[ec]WL[643]C[
 Explorer 14k : unusual...
]
;B[db]BL[619]C[
 Perception NR : And another idiot move.
]
;W[eb]WL[630]C[
 Perception NR : It was doing so well for a while there.
 Explorer 14k : yes
]
;B[ad]BL[608]
;W[ag]WL[606]
;B[ci]BL[596]C[
 Explorer 14k : good
 Perception NR : Yes.  At least it saw that one.
]
;W[ai]WL[572]C[
 Explorer 14k : bad
]
;B[ea]BL[586]C[
 Perception NR : No, not bad.  Just not the biggest move around.
 Perception NR : Now H1, *that* was bad.
 Explorer 14k : very bad!
 Explorer 14k : f3 is best
]
;W[ah]WL[531]
;B[fa]BL[574]C[
 Perception NR : Yes.  But that's tricky.  Threat to invade.  Perception has a dim view of sente.
 Perception NR : It's heard of it, but doesn't think much of the idea.
]
;W[da]WL[512]
;B[ib]BL[564]C[
 Perception NR : Now it's just firming up it's territory.
 Perception NR : Looks like you'll win...
]
;W[fg]WL[487]
;B[fi]BL[551]C[
 Perception NR : Oh no.
]
;W[fh]WL[432]
;B[ei]BL[536]C[
 Explorer 14k : hmm, looks like we get something
 Perception NR : Looks like I'm in big trouble.  :-(
 Perception NR : It saw G2 and F1 as being equal in value, picked F1 at random.  Why not the other way!  :-(
]
;W[gh]WL[394]
;B[ac]BL[526]C[
 Perception NR : Now it thinks that you are winning by 24 points
 Perception NR : Until g2 it thought you were winning by only 5
]
;W[hh]WL[371]
;B[if]BL[519]C[
 Explorer 14k : maybe more now
]
;W[hg]WL[347]C[
 Perception NR : Yes, I think that you are winning by more than that.
 Explorer 14k : H3 bad, must be J3
 Perception NR : Now let's see how much it thinks you have...
]
;B[dg]BL[365]C[
 Perception NR : It says W+43
]
;W[gi]WL[318]
;B[ih]BL[361]C[
 Explorer 14k : very odd
 Perception NR : J2?
]
;W[ig]WL[300]C[
 Explorer 14k : that too :)
 Perception NR : At least it wasn't a shutout.  :-)
 Perception NR : Or at least, not yet.
 Perception NR : Explorer is MUCH stronger than Poka and GoLife.
]
;B[ie]BL[310]C[
 Perception NR : Yay!
]
;W[fc]WL[289]C[
 Explorer 14k : last problem point
 Perception NR : Yes.  This should be easy for Perception.
 Perception NR : Tactical reading is perfect as long as liberties never exceeds 3.
]
;B[gb]BL[264]
;W[tt]WL[269]C[
 Perception NR : Hopefully perception will pass now.
 Perception NR : It may attack A1 group though.
]
;B[hb]BL[234]C[
 Perception NR : D'oh.
]
;W[tt]WL[259]
;B[dc]BL[219]C[
 Perception NR : Argh.  I'll resign to end this.
]
;W[tt]WL[251]
;B[gg]BL[206]C[
 Explorer 14k : ok
 Perception NR : Hmmm...wait...should end itself in a move or two...
]
;W[tt]WL[238]
;B[tt]BL[196]C[
 Perception NR : Good!
]
;W[tt]WL[238]C[
 Perception NR : It passed finally!
