is chess a violent sport

Do you believe that chess is a bit violent?

I think a lot of the players are suffering from head injuries.

Yep, it's pretty brutal.

Hockey is a violent sport.  Chess, not so much.  I'm not even sure if chess could be called a sport, but that's a whole different forum topic. 

It can be sometimes if you are playing in a bar.

Yes.

It's not for the faint-hearted.

(White_Rabbit has obviously never played chess in a bar in Europe.)

Anything involving competition and losing could lead to violence.  I'm sure somewhere there have been brawls over a heated round of Bingo, but in general I'd say chess isn't that violent. 

And I'm guessing that alcohol may have played a bigger part than chess in those violent European bar games, but Netzach is right, I've never played chess in a bar in Europe. 

Your'e damn lucky you're white and not a ferret White_Rabbit otherwise we coudd hve ben choosing the music for the last gambol.

Yep, especially if you start cheating and take someone's pawn while mumbling some strange French phrase like "en passant".
