Hello, Elle!
A "stinker", indeed!
One of the Championship puzzles.
20, "Sensor",
Now, this is my stab at the parse!
"Sensor" is a "detective gadget".
"s" for "succeeded" inside the Spanish word "senor".
I think Cid could possibly be senor.
There was an "El Cid" but who that was I have no idea!
26a, is "baize" sounds like "bays/howls"
The spider is a snooker implement and the snooker table is covered in baize cloth.
6d, is "redaction"/censorship, the October Revolution could be Red Action?
18d, "I'm 1 table"/"imitable", there could be a "nest of tables", I think. I think they come in threes?
23d, anagram, "anime" is a kind of film.
It was certainly a tough puzzle today, Elle.
You have done well!
