2...f5 blitz game with the Vienna

I had black and decided to try 2...f5 against my opponent's Vienna.

Nice game! 

I'd might have tried 4...d6, trying to castle Queenside, fianchetto on g7 and launch a pawn storm on the kingside, but your opening choice and gameplan also looks very good. This e4 pawn reminds me of the d4 pawn in the Albin Countergambit, and your mate is very nice.

Thanks!  I decided not to go queenside because I had a feeling that the rooks would need to be on the f and e files, and castling kingside gets that done one move faster since the rook's already on the f file.
