Chess Terms in Spanish

I would like to know more of the terminology of chess in Spanish.  I think some of the pieces translate pretty readily.  King = Rey, Queen = Reina or maybe Dama, Rook = Torre, Pawn = Peón.  But I am not as sure of Knight = Caballo? or Bishop = Alfil?  

There may even regional differences.  

If you are able to help me with the terminology translation, please let me know.  I have other phrases that I would like to ask about that may not translate literally such as "make a move".

Thank you.

A very good start can be found at http://expochess.tripod.com/spanish.htm

Knight = Caballo(horse) and Bishop = alfíl, that's ok

pdela sabes como se dice "backrank mate" en español? 

maldito socialista!

ahhhhhhhhhhh 

cómo se dice?

Thought knight was "caballero" though I am more than likely confusing languages

literal translation of Knight is "caballero", but in Spanish (at least in Spain) the chess piece is called horse ("caballo")

Makes sense, like I said I may be confusing stuff learned most of my Spanish in Texas so its much less formal than Castilian

Consulting the list of Chess Terminology : English-Spanish at http://chess.expoparkla.com/spanish.htm  ,

knight[n.] el caballo

The queen is Dama not Reina.

pdela, no he encontrado a nadie que sepa como se dice backrank mate, porque "mate trasero" no suena demasiado bien 

I say Dama, hardly ever I have heard Reina

I always heard Reina... but from people that don't usually play chess.

It has become clear that there are some differences between countries.  I have learned that Roque is used for Rook although Torre is also used. It occurs to me that even in English, people will sometimes refer to the Queen and the Lady and on occasion someone with call the Knight a Horse.  Es lo mismo en español.

I have never heard somebody call the rook a roque, what they said is "castling" = "enroque".

Guys, it's caballero for knight. Caballo is horse, a caballero is a knight. As for bishop, that is obispo.

Nobody call "obispo" to the bishop, they call it "alfil".

But in portuguese, they call it "bispo".

It is true that a Bishop translates as Obispo but in both dictionarlies I checked, in the the context of chess, Bishop is Arfil.  Likewise, the dictionaries give Caballo (horse) as the word for Knight in the context of chess.  Roque and sometime Torre is used for Rook and castling is el enroque.
