I'm getting tired. All the lookaheads in this case will come right from the
two sided database and have janowski applied to them (I forgot that we aren't
in a contact position for a moment - brain phart). All the evals should come
really fast because of this (even on larger plies). On each lookahead the
static evals from the database are reapplied with janowski up to the given ply.
One other thing I'd like to know. If you take the same position as a money
game in XBG can you also post the results. I'd be curious to see how the values
between a XBG's money eval and Match eval differ.

Not necessarily. Interestingly enough on one ply It says double/take but
that based on the potential 21 rolls and their resultant equities (each that
will also have janowski applied). It also assumes the cube is seen within the
plies that are given.
I have a question for you. On simple 0 ply what are XBG's results? Would
you post them. I'd be curious.

Surely, therefore, at least 1-ply or higher should see the recube and the
then dead cube situation and go to the DB for an exact valid value.
