No worries, no offence taken. I only do my unpleasant duty as a moderator.
Game scores are allowed if
1) they are hard to find (thumb rule: not in TWIC and Megabase);
2) are accompanied by verbal explanation (why is ...Rd4 and R8d5 so strong?);
3) are accompanied by concrete analysis (do an attempt to find the best reaction for White).
Combining these three is even better. If you still want to draw attention to an important game without any comment it suffices to give the name of the players, the event and the year.
Main reason is readability.
(Yes, putting them in a file is also allowed)

MNb's posts probably deserves an amendment (with no offense to him intended) that the updates are welcome, but the games should be attached in PGNs to save space and such. I have no problem with it being presented like this, as it's easy to copy and paste them into Chessbase, but for some reason (I just can't remember), Tony doesn't like to see them posted like this.

When I looked at this position the first time was when Pontus Carlsson face it in swedish elite a few years ago and played a direct Rd5 and I thought that Bc4 was an improvment that looked realy good for white.

I also does not see any differeces by losing a temo, a white pawn to h4 does not weaken whites position.

I analysed with Rybka 2 a few years ago coming to the conclusion that the move 18 .. Rd7 was blacks best option, intening to double at d file and play c5(after Bd3, h4 without Bd3 Queen to dfile) but white can get a slighlty better endgame by accurate play.
 
EDIT I asses this as whites most dangerous try agianst the Bjerring variation

The line you gives is one of the critical lines, an other critical line if the rare and underrated 18 Re1.
In recent GM practise black gets a draw without any difficulties after Rd5. One model games is Fedorchuk-Timofeev 2009. It also appears that Bd5!? as in Vocaturo - P Carlsson 2008 is playable with the idea of preventning any exchange sacs at e6 but there might be some serious improvments for white to get a slightly better positon.

Blacks strutural weakness is often compensated by active pieces and potential attacks agianst queenside, (and sometimes even kingside pawns) where Rooks , Queen and Bishop can easely target whites king. Also blacks pieces are in more attacking position than whites. But I agree that Petroff might be a more simple way to get a draw . Several players like Kasimdzhanov actually swithes between Dragon and Petroff. At the subscrition section of this site they conclude that this line has put out 9 0-0-0 mainline as a serious winning try as white is struggeling for any advantage at all.

EDIT

On Rogozenkos disc Dragon 2 Khalifman recommended this system for black (primary recommendatrion and mainline e5 secondary recommendation) and called the line an interesting pawsacrifice where black hopes that hes better development will give him enough counter for the pawn and that it seemed to be true. But he did not discusses the line in high detail.

Also, this line had an article in Chessbase Magazine 114 but there has been lots of developments since that article, and mostly positive for the black side.

While Dearing in Play the Sicilian Dragon main recommendation was e5, he mentioned the line in passing, showing a few variations, and wrote that he would be confident in playing either side in this variation and he assest the position as pretty equal.

Today the match between Dominuez and Smerdon continued in form av tie break rapidplay games.
Domuniuez first returned to Bc4 yugoslav (including allowing Chinsese) where Smerdon came ut with an new interesting plan and white could not get through  anywhere so draw was agress after repeting the same position.In game number two white choosed a solid 0-0 line where black could have eqaliced  at once by d5 as in in Kamsky-Radjabov (i think). Smerdon had the draw in the endgame but white had better moves before.

Also, Shabalov played Dragon and won agianst Baklan in the Carlsen/Radjabov (origianlly invented by Rogers) line Bxd4 agaisnt Experts vs Sicilian line. 
but tat game would be little mroe out of topic than it alreay is. If hope Ward and Jones annototates the Yugoslav attack games between Dominueuz and Smerdon.
