IM David Pruees produced an interesting novelty (4.Bb5+) in round 3 of the US Championship 2008 against IM Dean Ippolito. The strength of the novelty is debetable but it did produced an original position. To make more interesting, Pruess are willing to skip castling around move 7 and 8 . He also set an excellent exchange sacrifiece on move 12, sacrificing both his rook for black queen.
