David, thanks but what do you mean by the last comment -

Using (SELECT uid FROM myself) provides the same result without the from/join reference; the usage in the case and the where clause could be rewritten to use opponent.uid so myself.uid only appears once.
I have applied your first 2 comments in
WITH myself AS (
SELECT uid
FROM words_social
WHERE social = in_social
AND sid = in_sid
)
SELECT
CASE WHEN c.uid = myself.uid THEN 1 ELSE 0 END,
c.msg
FROM words_chat c
JOIN myself ON TRUE
JOIN words_games g USING (gid)
JOIN words_users opponent ON (opponent.uid IN (g.player1, g.player2) AND opponent.uid <> myself.uid)
WHERE c.gid = in_gid
-- always show myself my own chat messages
AND c.uid = myself.uid
-- otherwise only show messages by not muted opponents
OR NOT opponent.muted
ORDER BY c.created ASC;
but where to put the (SELECT uid FROM myself), I do not understand?
