This is from the [0,1]game series by Chen/Jerrod on
RGP. r is from part 3.

r=.414

r is the "golden mean of poker".

Use the reciprocal of r. Bet if your hand has a
linear hand strength(LHS) of .586 against your
opponent's range of hands. Range of hands sounds
so awkward. Will use hand space instead of range
of hands.
Square r, cube r and quad r for .171, .071 and
.029. The corresponding LHS are .829, .929 and
.971. You should raise with a LHS of .829.
Reraise with .929 and cap with .971.
This assumes both you and your opp are rational.
Both are trying to win. Also assumes neither
will fold.

In practice this isn't necessarily true. Many
opps fail to adjust to new info. Against these
opps you can and should often rebet your same
values.
