10-games match at H7 between gnugo 3.8 and LZ_variable-komi 0.3 with weights #157
LZ wins 9-1 (7 times W+R, 1 time B+R, 2 times W+xx.5)
1x1080, twogtp v1.4.10, --visits = 3201 and no pondering for LZvk, komi 7.5 (so, it's more like H6) , no additional commands used (-r, --max-wr , --min-wr ,--mid-wr etc.)

I should have added the -r 0 command (= never resign !) for the H7 and H8 games, because LZ_vk probably resigned too soon in some of them.

Anyway, very nice wins !

Impressive... Pachi seems to deal very well with high handicap.

Yes, I think so.

Some Sabaki games against LZ0.15 at 1D, 2D, 3D, 4D and 5D (according to the ranking of LZ)

Laptop with GTX965M, and i7-6700HQ

LZ parameters : --visits=3201 -r 10 --noponder
Pachi parameters : -t =10000:30000 --dcnn

Pachi won against
1D (network 55bf5)
2D (network ded4)
3D (network 714a9)
4D (network e1156)

but lost against
5D (network b3b00)

Pachi seems very strong at high handicap : it won against gnugo at a real H9 (komi 0.5)
Maybe, it uses dynamic komi (I've seen something called dynkomi, somewhere)

There's an Android app too, but it's very slow.
