Long (200+ move) forced mate

I remembered this morning reading an article about a GM tournament from a couple years ago where in one of the games there was an endgame which was spectacular. I think it was R+B against N+N, and there was apparently a forced win in something over 200 moves. Of course this would've violated the 50 move rule, but the GM also missed it anyway. For several of the moves, nobody really knows why that particular move mates faster than the rest, but it's in the endgame tablebases. I searched for this game for about two hours earlier today, but couldn't find it. Does anybody else remember the game? Does anyone remember how many moves it was exactly, or who played it? Can anyone find a link to the article? It's driving me crazy, so your help would be appreciated. FYI, I remember seeing the report of chessbase.com

Here we go:

Karjakin, Sergey (2694) - Shirov, Alexei (2739)
World Cup Khanty-Mansiysk RUS (6.3), 11.12.2007

Thank you!

It would have been pretty funny if that was the winning sequence Deeper Blue beating Kasparov.

lol

How the hell could we remember such a random game?  =)   Most of us aren't chess historians and you should probably recognize the fact that we are Joes playing chess to relax.  If anyone remembers that game, I give you credit.

I remember it for the long long long forced mate in the article on chessbase discussing it. I didn't really expect anyone to be able to point me to it, but figured it couldn't hurt. And luckily someone did. I don't know why you have such a problem with me.

Very strange post. It's extremely likely that someone on chess.com found such an extraordinary game interesting enough to remember it.

wow

Just a fun fact:

"During the time periods when the fifty-move rule admitted exceptions, there were a number of revisions. At some point, the rule was changed to one hundred moves for such positions. Later more positions requiring more than fifty moves were found. FIDE included these endgames in the extended rule:

1. queen versus two bishops
2. queen versus two knights
3. two bishops versus a knight
4. two knights versus a pawn
5. rook and bishop versus a rook, and
6. a queen with a pawn on the seventh rank versus a queen.

The one hundred move extension was in force for a few years but it was changed to seventy-five moves in 1988 (Hooper & Whyld 1992)."
