Hi Robert,

This is a game of the Carlsen-Svidler Match 2006. The test position is in the current version of Jon Dart's Arasan.pd test suite.

I think the sacrifice is only good enough for a draw, but Magnus (playing black) went wrong and lost.

The game and pgn are here: http://www.chessgames.com/perl/chessgame?gid=1427754
