Win Against A Norwegian!?

Tonight i played a fascinating sacrifiece in one of my online blitz game in the Internet Chess Club (ICC) against a Norwegian nickname dryfish . After Norwegian Wonderboy - Magnus Carlsen (photo right) triumph at the recent Corus 2008 , It's nice to won a game against his fellow counterymen!!!

At first glance, i think the position looks pretty much equal. Perhaps white have a slight advantage due to black isolated d pawn but suddenly i found an interesting sacrifice idea base on the x-ray of my rook at d8 over white queen on d2! 16... Ne4!

17.Bxe4? white panicked. Actually he can still play on with 17.fxe4 dxe4 18.Bf4 Qc8 19.N3d4 exd3 although black still have the upperhand 17...dxe4 18.Qf4 Qxf4 19.Bxf4 Bxb3 0–1
