You always need to be extremely careful about these kind of
heuristics. Especially in MC programs they can be detrimental very
easily.
But I believe you can come up with a reasonable rule to prevent some
self-atari's. I have one which is something along the following lines:
- puts itself into ata
This case is of course not pruned by Valkyria, simply because the the
pattern here is completely different from what we discussed. :) This
sacrifice prevents an eye to be made.

In this case one needs to check that after the two stones are captured
the capturing single stone can be recaptured bringing us back to where
we started. If it is a "big eye" there is no recapture.

Suicide? Do you mean self-atari? But there must be more to it than that
because you don't have a rule that prevents all self-atari, right?

Valkyria behaves the same as Many Faces in this position. It sees
maximum 1% winrate for Black.
The seki is not really detected by Valkyria, J6 is simply pruned for
both players. For white it is just stupid suicide with too many
stones. For black I think I prune this kind of two stone suici
With X to move, Many Faces immediately gives about a 1% win rate, and after
a few seconds, resigns, showing 23742 playouts with 0.5% win rate. 10 ply

Not sure this helps, but...
I found send-two receive-one, as in your example, to be the most
common non-simple ko cycle in my program. The program was heavy, so
forbidding "send two" added little to the total cost. Specifically,
the rule forbade playing on an isolated empty intersection that

Is it possible to explicitly use a monospace font? I can't read your
board positions.
I haven't heard of any handling of seki in playouts except for Remi's
CrazyStone. I don't think he's ever given specifics on how he did it.
Maybe he'll respond to your e-mail?
