Does anyone know any chess tactics other than these:

Attraction
Back Rank Mate
Blocking
Capturing Defender
Clearance
Desperado
Discovered Attack
Distraction
Double Attack
Exposed King
Fork
Hanging Piece
Interference
Overloading
Pin
Sacrifice
7th rank invasion
Simplification
Skewer
Smother
Trapped Piece
Weak Back Rank
X-Ray Attack
Zugzwang
Zwischenzug
?

Are any not considered tactics but strategies (positional play)?

Are any of these repetitious?

Gaining opposition?

What is that?

getting a better position i think

From wikipedia:

In chess, opposition (or direct opposition) is the situation occurring when two kings face each other on a rank or file, with only one square in between them. In such a situation, the player not having to move is said to "have the opposition" (Flear 2004:12). It is a special type of zugzwang and most often occurs in endgames with only kings and pawns (Flear 2000:36). The side with the move may have to move the king away, potentially allowing the opposing king access to important squares. Taking the opposition is a means to an end (normally forcing the opponent's king to move to a weaker position) and is not always the best thing to do.

There are extensions of direct opposition, such as diagonal opposition and distant opposition, which can be conducive to reaching direct opposition. All three types may be referred to simply as opposition if the type is unambiguous in context.

While we're at it, you could also add "triangulation" and "gaining a tempo".

What are they?

Triangulation:

Triangulation is a tactic used in chess to put one's opponent in zugzwang. That is, it gets to the same position with the other player to move, when it is a disadvantage for that player to move, e.g. he has to give up a blockade and let the other player penetrate his position. Triangulation is also called losing a tempo or losing a move.

Triangulation occurs most commonly in endgames with only kings and pawns when one king can maneuver on three adjacent squares in the shape of a triangle and maintain the basic position while the opposing king only has two such squares.

Tempo:

In chess, tempo refers to a "turn" or single move. When a player achieves a desired result in one fewer moves, he "gains a tempo" and conversely when he takes one more move than necessary he "loses a tempo." Similarly, when one forces his opponent to expend moves (often in defense) that he would not otherwise have expended, one "gains tempo" because the opponent wastes moves.

very good.  thank you.

why does it seem more people are not interested in this list?

It must be common, huh, brought in the chess books...which book lists all of these?

Underpromotion

windmill

Double check (as distinct from double attack -- double check is an important tactic as it can only be answered by a king move)

Stalemate trap

Reloader attack

Double Rook sac

Greek gift sac

entombment (you've got this as "trapped piece")

domination

fortress

Also, I think a great deal of quibbling can be done regarding some terms not being tacitcs. You seem to be looking for what are called tactical themes, rather than very specific tactics... there are lots of named mates and endgame postions that aren't tactical themes exactly, but are named tactics, such as

Damiano's mate

Philidor's legacy

Legall's mate,

Lucena position

etc.

I believe "Deflection" is the more common term, rather than "Distraction" (if that is what was intended)

hm...I guess it would be a good idea to learn what these things are...

Reloader attack, sounds awesome - I want some of that action.

long oppostion when kings are 3 or 5 squares away

Eh, could 'Suffocation mate' be added...it's not a tactic but it's a strategic form of checkmate.

wow, I don't even know half the things mentioned here!

Nice Rorshach Blot!  Looks like a Sacrum...Etymologically related to Sacred and Sacrifice!  Why?

Yeah, that's already been listed as smothered mate and again as "Philidor's legacy" (although Philidor's legacy is a specific way of arriving at a smothered mate). The Double discovered check followed by Queen sac then mate is the Philidor's legacy technique... although it is most commonly seen against a 0-0 castled king trapped in the corner. This oooh-aaah impress-the-bystanders mate turns up surprisingly often and is worth knowing. Josh Waitzkin has said that in his junior chess days he "made a living" with it.

How bout intermezzo? It means "in between move." Here is an example...

THANK YOU SO MUCH JG27Pyth and rookandladder for the examples.
