Does this matter in real life? AIUI, RAVE without special modifications
(like those done in Mogo later) does not have any convergence guarantees
either. I suppose Valkyria uses RAVE, so RAVE acts as its exploration
term, like in Pachi.

By the way, in Pachi I have floating point values in nodes, so I just
count jigo as value of 0.5 (as opposed to 0 or 1). I have no further
special handling (as far as I can remember) and this works nicely as it
is. What Magnus describes sounds most like some implementation artifact
to me, but maybe Pachi just handles something else differently, avoiding
this as well then.

UNIX is user friendly, it's just picky about who its friends are.
