Everyone who likes sacrifices should have a look at this game between Magnus Carlsen and Geir Sune Tallaksen from the Norwegian championship: http://www.rogaland-sjakk.org/nm%202005%20sandnes/partier/klasse_elite/base_runde_5.htm (4th game)
I read that Fritz agrees 100% with Magnus' moves from move 20. Amazing!
The tournament ended with a shared first place for Magnus and his teacher, Simen Agdestein. There will be a play-off later this year.
