like someone else said, peertz, but pirk does sound better.
One funny thing about chess is the widespread mispronunciations
Ruy lopez is another one people have wrong, Its supposed to be said like Reese lopez. Once again, to me, the incorrect "Roy" sounds better
Also Kingscrusher says Jose (raul capablanca)in a funny way (this time it doesnt sound better)
I don't.
I also never attempt to pronounce Viswanathan. I just say Vishy.

Isn't it pronounced 'Hoy lopez' ?? Certainly not 'Reese lopez'. I think she's a Mexican porn star.
Yeah, doesn't exactly slide off the tongue

This is a really dumb thing to wonder about. You know All the in's and outs of the marshall variation, but you wonder how to pronounce.....ok....
Vasja is pronounced, "vas-ya"
In Germany it is commonly pronounced 'Pirk' but maybe it is pronounced 'Perk' in the rest of the world. Wikipedia may be right, but the majority of chessplayers thinks different.
Even better, the chess world has a bastardized version of Alekhine as well.
Just say "crip" backwards.
Can you use IPA-symbols please? "peerts" [piɹts] contains a phonem that is not existent in Slovenian, so I suppose it can't be pronounced in this way. I suppose it should be [piɾts], according to Wikipedia's article.
Having now lost 12 successive games with it, it's pronounced The Pits.

At last! the voice of reason.
pirc= pronounced Piehrtsch
pirc= pronounced Piehrtsch
Most definitely not. His surname was Pirc, Not Pirč.
As a Slovenian, living 11 km from Idrija, and with history of correcting Kingscrusher how to pronounce it (I can't find the damn comment), I'm just the right man for this thread. 
The pronounciation I recommended was "Peerts". Of course it's not perfect, but definitely much better than "Perk".
its Pieehrdsch, 100% sure
How do you pronounce "Vasja"?
Vasya would do I think. With short "y".
On an unrelated note, I think the pronouciation "perk" is so popular, that it is somewhat pointless to try and "correct" it.
its Pieehrdsch, 100% sure
Pirtz would be the German one.
Its pronounced 'pee -- eye -- are -- see'.
