If it were me, I'd run all anchor candidates against the current CGOS to
determine the anchor value to use for that anchor candidate.

I strongly believe current anchors are resource friendly enough for
older pentium 3, 4 or even Celeron processors and not necessary being
changed.
Changing anchors is a big problem, similar to changing the
International prototypes. Also, GNU Go is used as a reference in
almost every computer-go research these days.
I'm against that idea, especially for 19x19.

I'm trying now to get a rough idea about the strength of fuego and it's
suitablity as the anchor player.
Right now the numbers are very rough as I need more samples. I'm currently
looking at:
1. 9x9 fuego at 1000 simulations
2. 19x19 fuego at 3000 simulations.
I'm testing against the current CGOS anchors, so FatMan vs fuego at 9x9 and
gnugo-3.7.10 at 19x19.
At 9x9 fuego appears to be substantially stronger than FatMan, perhaps
100-200 ELO. It also is far faster at 1000 simulation than fatman which
requires many more simulations to reach anchor strength. So there is no
questions about fuego being a capable anchor for small boards. At this
level on 9x9 FatMan is also stronger than gnugo, so fuego is far stronger
than gnugo on 9x9 and is very resource friendly too.
At 19x19 the story is a bit different. gnugo appears to be significantly
stronger, but about twice as slow. There is not enough data to narrow this
down much, but it appears to be over 200 ELO weaker at this level.
Since fuego is using only about half the CPU resources of gnugo, I can
increase the level. I've only played 30 games at 19x19, so this
conclusion is subject to signficant error, but it's enough to conclude that
it's almost certainly weaker at this level but perhaps not when run at the
same CPU intensity as gnugo.
Of course at higher levels yet, fuego would be far stronger than
gnugo-3.7.10 as seen in the 19x19 cgos tables. But I'm hoping not to push
the anchors too hard - hopefully they can be run on someones older spare
computer or set unobtrusively in the background on someones desktop
machine.
