I know and they are still used but you are still talking
about raising the pot (not cultivating:) in limited and
preset intervals of doubling.
What I am talking about is being able to say "I see your
beaver" (never while playing against females, of course:)
"and I raise you fifty raccoons", (and without restrictions
on seeing anybody's raccoons), the opponent being able to
raise a herd of aardwarks, otters, etc... :))
