Yes, Brian. That’s what I do in Erica.

Then is this the condition? If a move X by your color is immediately after a Ko
capture by the opponent and immediately before a Ko capture by your color, then
do not count X in the RAVE update.

Honestly, I have no good method to detect a ko threat now. I guess that’s why I
got only 30 Elo in my experiment. Anyway, all we know for sure is that a ko
threat must exist between two ko captures (the latter one might be resolving a
ko). The principle is that these ko threats must not be updated in the nodes
before opponent’s ko capture.

Subject: [Computer-go] Aja's PhD thesis: Question about RAVE+ Ko Threat
In your heuristic for adjusting RAVE for Ko threats, how is the "ko threat"
identified?
The following conditions seem required:
1) You cannot capture the Ko on this turn because the opponent captured
last turn.
2) You make a move somewhere.
But are these the only conditions? For example,
- no requirement that a Ko exist in the current node (that is, the node in
which RAVE is being updated)
- no requirement that the "ko threat" actually threaten anything
- no requirement that the "ko threat" occurs within the tree (rather than
the playout)
Thanks,
Brian
