C[zapp [?\]: burtabel, viking does not use bensons it plays random games to the end
]
;W[kj];B[ck];W[ii]
C[zapp [?\]: And if all random games wins it simply plays any move
]
;B[hf]C[burtabel [3d\]: ok i see
];W[hj];B[dk]
C[zapp [?\]: But in a close game losing those stones would be a disaster
]
;W[ej]C[zapp [?\]: And in 99% of the case it will play correctly
]
;B[ek];W[ik]
C[zapp [?\]: I have actually never tested viking against gnugo on 13x13

C[zapp [?\]: Viking thinks it is slightly behind

;W[cf];B[le]C[gunnar [?\]: GNU thinks B+3.

C[burtabel [3d\]: yes after W C8 Black should be leading

C[zapp [?\]: Viking has problems with monkey jumps
burtabel [3d\]: gnugo too

C[gunnar [?\]: GNU thinks it's ahead by five points now.
];B[bg]
C[zapp [?\]: Viking is also more pessimistic
];W[ai];B[fj];W[jc]
;B[eh]C[gunnar [?\]: GNU doesn't seem worried about the left side.
zapp [?\]: Viking clearly wants to kill this large group
]
;W[ic];B[dg]C[burtabel [3d\]: well its dead now
];W[gb]
C[zapp [?\]: Not in computer go...
];B[cg]
C[gunnar [?\]: Somehow the owl reading found out correctly but didn't play to defend it anyway.
burtabel [3d\]: maybe semeai overruled it?
zapp [?\]: This is often what happens when viking beats gnu
]
;W[ie];B[fb]
C[zapp [?\]: It desperately tries something and gnu stumbles on a bug 
]
;W[hd];B[gc]C[Gresil [16k\]: viking5 has superior luck code, eh
]
;W[hb]
C[zapp [?\]: Good comment. Since it is based on playing random games to the end it actually measures luck all the time
]
;B[fl];W[fm]
C[zapp [?\]: It plays the move that seems to possibly be the most lucky one

C[zapp [?\]: A move ordering problem makes it not see the points in the lower left
