Yes indeed you're welcome. This is fun, thanks to ... YOU!
Area light diameter 15
Faster dark wood
The king is staring at you. Look closely.
Rook halo not as visible with other pieces on the board
Lighter wood now needs adaptive 2 or higher, (see shadow behind king and queen).
Rook also demands higher adaptive level with other pieces present.
Area light diameter seems critical to lighting.

everyone who's anybody loved it.
Chocolate darkwood:
#declare p_darkwood =
pigment
{ wood color_map
{ [.4 rgb <0.45, 0.30, 0.15>*.6]
[.6 rgb <0.60, 0.35, 0.20>*.6]
}
turbulence .5
scale <1, 1, 10>*.5
}
#declare darkwood =
texture {
pigment { p_darkwood }
//finish { boardfinish }
finish { ambient .1 diffuse .6 phong .5 phong_size 50 reflection 0.025 }
scale 0.3
}

Again with the making of total sense. "Alain" such a nice sound, just try it,
"Alain" conjures images of angels ...

More fun with dispersion. The first image has quartz glass dispersion
(according to consts.inc) exaggerated 40 times. The second is exaggerated
40 times with the wavelengths reversed--AFAIK, physically impossible, but
pretty nonetheless.

That's so cool you have access to puterPower. 8+ hrs, that seems like 4 or more
times what I can do here.
Previous image was adaptive level 1.
I hoped.
You must have been using level 50 for a couple of reasons, because you *can* and
because it seems to need it.
Autostop: now there's a mindbender
Something about objects with holes.
One of those, "test to see if it saves time or does what you want it to do"
features.

I always use autostop. A hole in the middle of an object won't cause autostop
to err because autostop doesn't kick in until the first hit. A disjointed
union will not be a problem because it is treated as separate objects--unless
split_union off is set for that object, and i don't set split_union off for
disjointed unions.
Disjointed differences, isosurfaces and polynomials could cause autostop to err.
Now, split_union off is definitely a "test to see if it saves time" feature. My
experience has seen this double the rendering speed or slow it down 10 times,
depending on how it was applied. My tentative recommendation: apply it to
Round_Box_Union(), Round_Cylinder_Union(), and unions of similar complexity,
but don't apply it to anything more complex than those.
